Friction and tribocorrosion behavior of Fe-Cr-B alloys manufactured by laser directed energy deposition

The current assessment of tribocorrosion in alloys for mining machinery repair is insufficient. This study explored four Fe-Cr-B alloys with similar compositions but varying hardness. Dry and wet (water) friction tests align with the hardness hierarchy, indicating enhanced wear resistance with higher hardness. However, tribocorrosion tests yield diverse results. Notably, High-hardness alloys (JG-11# and 431) had many boride phases, displaying corrosion pits, leading to early corrosion failure. Low-hardness alloys (JG-3#) had fewer boride phases, indicating friction-dominated failure. Balancing both hardness and corrosion resistance, the alloy (JG-8#) demonstrates excellent tribocorrosion performance while ensuring the absence of micro corrosion pits.

Correlation between TiO2 nanotubes thickness and their tribocorrosion performance in simulated body fluid solution

Titanium dioxide nanotubes (TNTs) have been extensively researched for their enhanced biomedical characteristics, including biocompatibility, cell apposition, and growth morphology. However, there is a significant concern in metallic medical devices owing to micro-movements between implants and bone in aggressive environments due to wear and corrosion synergies, leading to adverse body responses and implant failure. In this study, TNTs on Commercially Pure titanium (C.P. Ti) with three different thickness layers were grown to correlate their corrosion and wear behavior. Initially amorphous after anodization, TNTs underwent annealing at 450 °C for 2 h to transform the distorted, into a crystalline structure. The characterization included X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray (EDX), X-ray Photoelectron Spectroscopy (XPS), and contact profilometry. Potentiodynamic polarization (PD) and tribocorrosion tests were conducted in Simulated Body Fluid Electrolyte (SBF). SEM micrographs showed TNT thickness layers of 314, 691, and 5280 nm, and X-ray Diffraction showed anatase transformation post-annealing. Results confirmed a significant influence of TNT thickness layers on corrosion and tribocorrosion properties, with higher current density obtained from PD for thicker TNTs layers, associated with surface fluorine content. During tribocorrosion, annealed samples demonstrated lower corrosion tendency, potential drop, and coefficient of friction. Morphology of worn surfaces and volumetric wear rate varied with TNT thickness layer and thermal treatment.

Evaluation of tribocorrosion performance of Ti6Al4V alloy in simulated inflammatory and hyperglycemic microenvironments

The poor tribocorrosion resistance of the Ti6Al4V alloy limits its wide applications in orthopedics. In addition, the tribocorrosion performance and mechanism of the Ti6Al4V alloy are not clear in some clinically specific pathological settings, such as peri-implantitis and diabetes. In this work, the tribocorrosion performances of the Ti6Al4V alloy in simulated body fluids (SBF) containing H2O2 and glucose were investigated to analyze the degradation behavior in the simulated inflammatory and hyperglycemic microenvironment. The tribocorrosion tests were carried out on a tribometer equipped with a three-electrode system electrochemical workstation. The material volume loss of the Ti6Al4V alloy in the high glucose environment (6 g/L) is 3.1 times more than that in the glucose-free environment, while H2O2 does not increase the material volume loss. The continuous corrosion product film on the Ti6Al4V surface in the SBF with H2O2 acts as a lubricant in mechanical wear, while the Ca and Mg-containing mineralized film formed in the high glucose environment increases the coefficient of friction (COF) during sliding. These results suggest that diabetic patients may be at a higher risk of the implant failure due to the tribocorrosion. This finding also provides a valuable reference for the placement of titanium-based implants in specific pathological settings in orthopedics.

Tribo-corrosive wear behaviour of squeeze-casted Mg/TiN/hBN composite under different ageing temperature

The combined and individual effects of adding hard TiN ceramic particles and soft hBN solid lubricant particulates on AZ91D magnesium alloy were studied by analysing the tribocorrosion behaviour under various ageing conditions. The proposed materials were fabricated through the Stir-Ultrasonication-Squeeze casting technique and T6 heat treated at various ageing temperatures (170, 200, 230, and 260 °C). The tribocorrosion test results revealed that the ‘AHTT’ hybrid composite had a high corrosion potential (Ecorr) of − 1.38 V, low corrosion current density (Icorr) of 1.82 × 10−6 A cm−2 and low corrosion rate of 0.049 mm/yr. at 200 °C due to grain strengthening, formation of protective tribo-films and H3BO3 precipitates reduce the oxidation reaction during wear and corrosion. At a temperature of 200 °C, the nyquist plot reveals the presence of capacitive loops at both high and medium frequencies, which can be attributed to the formation of a thick tribo film layer that functions as a protective barrier. Furthermore, the stable reprecipitated secondary β-Mg17Al12 acts as a cathode, effectively restricting the formation of Mg+ ions.

Microstructure, mechanical properties and tribocorrosion characteristics of (Mo1-xCrx)5Si3 alloys

(Mo1-xCrx)5Si3 alloys were prepared by vacuum arc melting technique. The microstructure and mechanical properties of (Mo1-xCrx)5Si3 alloys were characterized using a scanning electron microscope (SEM), X-ray diffraction (XRD) and nano-indentation tests. The tribocorrosion characteristics of the alloys were investigated using a tribocorrosion tester in 3.5 wt% NaCl solution. The results revealed that the thermal expansion anisotropy ((CTE(c)/CTE(a))) of the (Mo1-xCrx)5Si3 alloys decreased from 2.25 to 1.45 with increasing Cr content. The Cr-alloyed (Mo1-xCrx)5Si3 alloys exhibited a high hardness, and their fracture toughness, ratios of H3/E2 and H/E were improved. (Mo1-xCrx)5Si3 alloys showed a strong wear-corrosion combined effect, and an opposite trend between friction coefficient and OCP values was observed during the tribocorrosion tests. The tribocorrosion resistances of (Mo1-xCrx)5Si3 alloys were better than that of 0Cr18Ni9 stainless steel due to the formation of Cr2O3-MoO3-SiOx protective films. The (Mo0.8Cr0.2)5Si3 alloy exhibited the best tribocorrosion characteristics with a low friction coefficient and wear rate. For the 0Cr18Ni9 and Mo5Si3 alloy, pure wear (Vw) was dominant, nevertheless, corrosion-induced wear (Vcw) was the main tribocorrosion mechanism of (Mo0.8Cr0.2)5Si3 alloy.

Enhanced corrosion and tribocorrosion behavior of plasma electrolytic oxidized coatings on 5052 aluminum alloy with addition of pullulan to silicate electrolyte

Plasma electrolytic oxidation (PEO) ceramic coatings were fabricated on a 5052 aluminum (Al) alloy using a silicate-based electrolyte with the pullulan addition, and the effects of different pullulan concentrations on the corrosion and tribocorrosion resistance of the coatings were investigated. The morphology, chemical composition, phase structure, and mechanical properties of the coatings were observed via scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, and scratching. The corrosion and tribocorrosion properties were evaluated via electrochemical tests and tribocorrosion tests in a 3.5 wt% NaCl solution, respectively. As a result of the pullulan addition, the phase structure of the coatings was slightly affected, but their microstructure and mechanical properties were significantly altered. The PEO coating displayed the smallest pore size and densest structure at a concentration of pullulan addition of 1.0 g/L. The corrosion current density of PEO coating was 2.41 × 10−8 A/cm2, which was two orders of magnitude lower than that of the Al alloy substrate. In addition, under tribocorrosion conditions, the wear rate of PEO coating was only 4.6 × 10−6 mm3N−1m−1, which was 91.8 % lower than that of the substrate, indicating excellent corrosion and tribocorrosion resistance. This study provides guidelines for the development of a sustainable and eco-friendly corrosion inhibitor for PEO coatings on Al alloys.

Effects of carbides on abrasion-corrosion performance of carbide reinforced composites in saline silica slurries

The abrasion-corrosion resistance of bonding matrix materials for impregnated diamond bits reinforced individually with WC, TiC, Cr3C2, and B4C particles was investigated in an alkalic saline silica slurry. Potentiodynamic polarization and electrochemical impedance spectroscopy were used to investigate their corrosion behaviors. The worn surfaces’ morphology and the compositions of corrosion products were characterized. The results show that the weight loss of WC or TiC reinforced composite during tribocorrosion test was much lower than that of Cr3C2 or B4C-based composite; compared with WC-based composite, TiC- and Cr3C2-based composites had better corrosion resistance, consequently decreasing their synergistic effect of abrasion and corrosion. Therefore, TiC could be a potential substitute for WC as reinforcing phase in the bonding matrix for impregnated diamond bits.

Wear and corrosion properties of CP-titanium coated with Chitin–Ceramic nanocomposites

Commercial pure titanium (Cp-Ti) is widely used in many industrial and biomedical fields. However, depending on the conditions of use of Cp-Ti, it exhibits low wear and corrosion resistance, thus reducing its service life. Therefore, in this study, the cuticle of the Japanese jewel beetle (Chrysochroa rajah) was morphologically examined and duplex coatings were produced by dip coating technique on Cp-Ti to provide protection against wear and corrosion by imitating the layered structure of the Chrysochroa rajah cuticle. Duplex coated surfaces were obtained by dip coating technique with chitin as the first layer and TiO2, SiC and h-BN layers as the second layer, respectively. Electrochemical corrosion properties were investigated under Simulated Body Fluid (SBF) solution. In electrochemical corrosion tests, open circuit potential (OCP), electrochemical polarization and electrochemical impedance spectroscopy (EIS) analysis were performed. Wear tests were performed in dry and SBF solution, and tribocorrosion tests were performed in SBF solution. The chitin + h-BN duplex coated surface has the highest corrosion potential (Ecorr) of -14 mV and the lowest corrosion current density (icorr) of 1.060 × 10−9 A cm−2. In addition, chitin + h-BN duplex coated surface has the highest corrosion resistance among duplex coated surfaces with corrosion rate of 4.601 × 10−4 mpy. In the wear test results, the lowest wear rate was 0.12 ± 0.011 × 10−3 mm3/Nm in dry environment and 0.28 ± 0.017 × 10−3 mm3/Nm in SBF solution on chitin + TiO2 duplex coated surface. In addition, the highest surface hardness was obtained as 4 ± 0.28 GPa on the chitin + TiO2 duplex coated surface. As a result of the tribocorrosion tests performed in SBF solution, the highest resistance was obtained on the chitin + TiO2 duplex coated surface. The chitin layer exhibited low corrosion, wear and tribocorrosion performance. Due to the effect of different electrical charge transfer and different hardness of organic and ceramic powders used in coatings, the coated surfaces improved the electrochemical, abrasion and tribocorrosion properties of Cp-Ti.

COMPARISON OF CORROSION, TRIBOCORROSION AND ANTIBACTERIAL PROPERTIES OF SILVER COATINGS ON Ti15Mo BY MAGNETRON SPUTTERING

The aim of this in-vitro study was to evaluate the influence of Ag[Formula: see text]-ion-coated conditions on the corrosion, tribocorrosion and antibacterial properties of Ti15Mo alloy. The mean wear volume losses of all test specimens after tribocorrosion test procedures were determined using a noncontact 3D profilometer. The specimens’ hardness, roughness values and microstructures were measured using the microhardness tester, surface profilometer, scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. The mean wear volume loss of 30-min Ag[Formula: see text]-ion-coated Ti15Mo alloy was lower than the other specimens. In this study, correlations between the hardness, surface roughness and wear volume loss were found to be significant. The PVD coating process enhanced the antibacterial activity of Ti15Mo alloy owing mainly to the formation of silver film on the substrates.

Current and friction transients during tribocorrosion of a biomedical titanium alloy sliding against zirconia

The tribocorrosion mechanisms of a Ti–Nb–Zr–Ta (TNZT) alloy rubbing against a zirconia ball in a Phosphate Buffered Solution (PBS) were analyzed by considering the mechanical and chemical interactions that lead to the material degradation. To understand the governing mechanisms, tribocorrosion tests were carried out in a ball on flat contact and reciprocating tribometer applying two normal loads (6.7 and 11.2 N) and two different anodic potentials (400 and 1500 mV). Worn surfaces were characterized by SEM and FIB cross sections as well as surface analysis. During the tribocorrosion tests, transients consisting in simultaneous abrupt current increase and a decrease in the COF were found at different instants of the tests. Subsurface cracking as well as third body build up were observed. These different phenomena and their temporal sequence could be described by initial sliding tribocorrosion, including metal particle removal and surface oxidation, followed by the build-up of a protective third body. After a certain number of sliding cycles subsurface cracking due to strain accumulation beyond a critical level lead to the detachment of a large particles that reactivated the initial tribocorrosion process. This mechanistic view could be substantiated by a model based on a quantitative analysis of the results.

Tribo-corrosion interaction of the parallel steel wires in the suspension bridges

AbstractThe effect of contact load and relative displacement on tribo-corrosion interaction of parallel steel wires of main cable in the suspension bridge was investigated in this study. A self-made tribo-corrosion test bench was employed to conduct tribo-corrosion tests of parallel steel wires in 3.5% (wt%) NaCl solution and deionized water under different contact loads and different relative displacements. The friction coefficient and wear coefficient of wires were presented. Electrochemical corrosion behavior (Tafel polarization curves, Nyquist diagram, and equivalent circuit diagram) was characterized by electrochemical analyzer. Wear morphology was observed by scanning electron microscope. Wear volume loss and corrosion-wear interaction were quantitatively demonstrated by high-precision weighing balance. The results show that the electrochemical corrosion ability of the steel wires increases with the increase of the contact load or relative displacement. The increased contact load or relative displacement increases the volume loss of corrosion-wear and pure wear, but decreases the wear coefficient. The wear mechanisms in 3.5% NaCl solution are adhesive wear, abrasive wear, and corrosive wear as compared to adhesive wear and abrasive wear in deionized water under different contact loads. The wear mechanisms of parallel steel wires are slightly different under different relative displacements. But the main wear mechanisms are similar to that under different contact loads. The interaction effects of corrosion and wear produced by the contact load and relative displacement are all the synergistic effects.

Investigation of the Influence of High-Pressure Torsion and Solution Treatment on Corrosion and Tribocorrosion Behavior of CoCrMo Alloys for Biomedical Applications

In this study, the influence of the high-pressure torsion (HPT) processing parameters and solution treatment (ST) on the corrosion and tribocorrosion behavior of CoCrMo (CCM) alloys was investigated for possible usage in biomedical applications. The corrosion behavior of the CCM alloys was investigated by using potentiodynamic scanning (PDS) and electrochemical impedance spectroscopy (EIS) tests. Tribocorrosion tests were carried out in a reciprocating ball-on-plate tribometer at 1 Hz, 1 N load, and 3 mm stroke length for 2 h. All electrochemical measurements were performed using a potentiostat in standard phosphate-buffered saline (PBS) solution at body temperature (37 ± 2 °C). The samples were characterized by using a scanning electron microscope (SEM), transmission electron microscope (TEM), optical microscope (OM), and X-ray diffraction (XRD). The deepness and width of wear tracks were examined by using a profilometer. The results showed that HPT and ST processes did not affect significantly the corrosion resistance of samples. However, the ST-treated samples had a higher material loss during sliding in standard phosphate-buffered saline (PBS) at body temperature as compared to HPT-treated samples.

Effect of laser surface texturing and boriding on the tribocorrosion resistance of an ASTM F-1537 cobalt alloy

Different kinds of materials are broadly employed to manufacture bioimplants. Metals are commonly used for the fabrication of lower body components such as knee prostheses and hip replacements because of their good mechanical properties. Among the available metallic biomaterials, cobalt alloys are commonly used. However, the hostile environment of the human body promotes the corrosion of the metallic bioimplant, and the wear due to the sliding contact could also increase the corrosion. There is, therefore, a constant attempt to study the surface of metallic biomaterials to enhance their functionality. In the present work, two kinds of surface modification techniques were employed on ASTM F-1537 cobalt alloy samples: laser surface texturing and boriding. Tribocorrosion tests were carried out using a linear reciprocating tribometer coupled with a standard three-electrode electrochemical cell. Tafel polarization plots were used to calculate the material loss due to corrosion. Also, non-contact profilometry was employed to estimate the tribocorrosion volume loss. In addition, the worn tracks were analyzed by scanning electron microscopy and energy-dispersive X-ray spectroscopy. The textured + borided samples increased 1.5 times the tribocorrosion resistance compared to the untreated samples. The differences in the tribocorrosion performance among the modified surfaces were discussed in this paper.

Tribocorrosion behavior of graphene-based solid lubricants biofunctionalized with hyaluronic acid on CoCr surfaces

In this work graphene-based solid lubricants biofunctionalized with hyaluronic acid were deposited on CoCr surfaces to decrease wear-corrosion phenomena. Graphene oxide was electrochemically reduced on CoCr in an aqueous suspension of graphene oxide 4 g/L by cyclic voltammetry. Biofunctionalization in phosphate buffer solution with HA 3 g/L (PBS-HA) for 24 h was performed. A pin-on-disk tribometer with an integrated cell was used for tribocorrosion tests. Wear-corrosion tests were performed against AISI316 steel balls applying normal load 1 N, 120 rpm for 500 m, in PBS and PBS-HA. Coefficients of friction in PBS were higher than in PBS-HA. ErGO and HA-ErGO increased wear rate in AISI316 balls, i.e., ErGO hardens the CoCr surface. Biofunctionalization reduces abrasive properties of ErGO deposits.

Amorphous/quasi-amorphous CoCrMo-C coatings for improved electrochemical properties and tribocorrosion resistance of biomedical alloys

Coatings based on CoCrMo cobalt alloy have been designed to increase corrosion resistance of AISI 316L austenitic steel in body fluids. The CoCrMo-C coatings, with different carbon content (from 0 to 65 at.%), were synthesised by reactive magnetron sputtering of the medical CoCrMo (ISO 5832-12) alloy in the argon-acetylene atmosphere. Evolution of their structure, crystalline phase and chemical composition with increasing carbon fraction were investigated by X-ray diffractometry and X-ray photoelectron spectroscopy. Evaluation of corrosion resistance of CoCrMo-C films on 316L steel substrates was performed in Hanks' Balanced Salt Solution (HBSS) by means of electrochemical impedance spectroscopy and potentiodynamic polarisation tests. The studies have revealed high chemical inertness of all coatings. Passive/blocking layers formed on their surfaces exhibit a capacitive character, while their resistivity is nearly two orders of magnitude higher compared to the corresponding values obtained for the CoCrMo and 316L alloys tested under similar conditions. The CoCrMo-C coatings provide pitting corrosion protection for 316L austenitic steel. This is expected to extend the residence time of stainless steel in the tissue environment. The 316L/CoCrMo-C systems were also subjected to tribocorrosion tests in HBSS at three electrochemical potentials, i.e. at open circuit, cathodic, and anodic potential. A model was developed to relate the electrical values recorded during tribocorrosion experiments with the phenomena that characterize the coating wear process. It was found that the friction coefficient systematically decreased from 0.7 to 0.1 with increasing the carbon content under all potentials applied. The wear rate observed for majority of the coatings was lower than that for CoCrMo and 316L alloys. For the samples with the highest carbon content, the wear rate under oxidative conditions became even lower than for the cathodic potential.

Assessment of improved tribocorrosion in novel in-situ Ti and β Ti–40Nb alloy matrix composites produced with NbC addition during arc-melting for biomedical applications

Nontoxic and nonallergenic β-type Ti–Nb alloys are considered attractive metallic materials for long-term bone implant applications. However, metallic implants present poor wear resistance, and the degradation process can be intensified with the friction occurring in corrosive body fluids, such as joint prostheses. The present study aimed to improve the tribological behavior of Ti–Nb alloys by adding hard reinforcement. The applied strategy is based on in-situ conditions, in which the reinforcing phase can be synthesized during the fabrication of the composite. Thus, a strong interfacial bond can be achieved due to the high chemical compatibility between the matrix and the reinforcement. Therefore, two different in-situ composites were developed by adding NbC powder to Ti and β Ti–40Nb alloy during the arc-melting process. As-cast samples of Ti and β Ti–40Nb alloy without NbC were used as the control groups. Structural characterization was performed, along with corrosion and tribocorrosion tests in a phosphate-buffered solution at body temperature. Results demonstrated that in-situ reactions occurred during the arc-melting process and promoted the precipitation of TiC as the reinforcing phase surrounded by α Ti phase (when NbC was added to Ti), and by β Ti–Nb phase (when NbC was added to Ti–40Nb). Finally, both produced composites showed improved tribocorrosion behaviors with wear volumes less than half of that recorded by the unreinforced Ti and β Ti–40Nb alloy. Thus, this study presents promising alternatives for wear-resistant biomedical applications.

Tribocorrosion Performance of WC-12Co HVOF-Sprayed Coatings Reinforced with Carbon Nanotubes

WC-12Co HVOF-sprayed coatings (~400 µm in thickness) reinforced with multiwalled carbon nanotubes (MWCNTs), were deposited on a steel substrate. The aim of this work is to provide and analyze data from HVOF WC-12Co sprayed coatings, concerning the influence of the addition of MWCNTs on their tribocorrosion performance, in a 3.5% NaCl electrolyte. Electrochemical data (current density and corrosion potential from potentiodynamic polarization curves) and wear data (coefficients of friction, coating volume losses and wear constants) are reported for the coatings, with and without the addition of MWCNTs (labeled WCCNT and WCAS-RECEIVED, respectively), considering the synergistic effects of wear and corrosion coupling. Scanning electron microscopy (SEM) and profilometry are used to explain both the wear and corrosion mechanisms that account for each coating’s performance in this environment. During the tribocorrosion tests, similar wear constants, of the order of approximately 10−12 m3/Nm, were found for all samples, with an increase of ~20% due to the MWCNTs presence. However, for the coatings reinforced with MWCNTs, a remarkable increase in icorr, representing almost 3 times the icorr of the WCAS-RECEIVED coating, was determined. The above results illustrate the complex mechanisms that occur when these coatings are tested under tribocorrosion conditions, which give rise to concurrent interacting phenomena, involving both electrochemical and mechanical responses.

Effects of Cr contents on tribological and corrosion behavior of HVOF sprayed Ni-based alloy coating

High-velocity oxygen fuel (HVOF) spray process was employed to fabricate nickel-based alloy coatings composed of different chromium contents (NC-A, 7.15 wt%; NC-B, 16.98 wt%). Based on the results of the tribocorrosion test, a mechanical plowing effect can be observed on the coatings at low applied potential (< +100 mVSCE), and the wear behavior of coatings was aggravated by intensified corrosion effect when a higher potential (>+300 mVSCE) was applied. Through the quantitative analyses, we have concluded that the total weight loss (Wtotal) of the coatings increased significantly as a function of the growing potential loading, and the synergic effects between corrosion and wear played a vital role in the overall weight loss.

Ti-15Zr and Ti-15Zr-5Mo Biomaterials Alloys: An Analysis of Corrosion and Tribocorrosion Behavior in Phosphate-Buffered Saline Solution.

It is crucial for clinical needs to develop novel titanium alloys feasible for long-term use as orthopedic and dental prostheses to prevent adverse implications and further expensive procedures. The primary purpose of this research was to investigate the corrosion and tribocorrosion behavior in the phosphate buffered saline (PBS) of two recently developed titanium alloys, Ti-15Zr and Ti-15Zr-5Mo (wt.%) and compare them with the commercially pure titanium grade 4 (CP-Ti G4). Density, XRF, XRD, OM, SEM, and Vickers microhardness analyses were conducted to give details about the phase composition and the mechanical properties. Additionally, electrochemical impedance spectroscopy was used to supplement the corrosion studies, while confocal microscopy and SEM imaging of the wear track were used to evaluate the tribocorrosion mechanisms. As a result, the Ti-15Zr (α + α' phase) and Ti-15Zr-5Mo (α″ + β phase) samples exhibited advantageous properties compared to CP-Ti G4 in the electrochemical and tribocorrosion tests. Moreover, a better recovery capacity of the passive oxide layer was observed in the studied alloys. These results open new horizons for biomedical applications of Ti-Zr-Mo alloys, such as dental and orthopedical prostheses.

A Tribological Investigation of the Titanium Oxide and Calcium Phosphate Coating Electrochemical Deposited on Titanium

Titanium (Ti) and its alloys are widely used in biomedical applications due to their excellent mechanical properties and biocompatibility. However, they are a concern due to the possibility of cytotoxic effects coming from the degradation products. This degradation occurs by the combined action of corrosion and mechanical wear of these materials, which are released in the biological environment by the biomaterial implanted. The present article aims to investigate a new route to improve electrochemical and tribological performance with surface modification. Regarding the deposition of a protective layer on the surface, it consists of titanium oxide (TiO2) and calcium phosphate (CaP). Both coatings were performed by chronoamperometric methods with titanium oxidation at 1 V and calcium phosphate reduction at −1.5 V. The corrosion and tribocorrosion tests demonstrated the effective combination of TiO2 and CaP layer to protect the Ti substrate. Furthermore, this coating combination reduced corrosion degradation and mechanical wear in PBS, simulating a physiological environment. Additionally, it was observed that this combination of coating decreased the dissipated energy, and consequently, the wear decreased during sliding tests. All these findings indicate the protective behavior of the TiO2 and CaP layer during the tribocorrosion tests.
