Abstract
The paper presents the investigation of a series of silver-incorporated diamond-like carbon (Ag-DLC) coatings with increasing Ag content on Ti50Zr and deposited using high voltage anodic plasma (HVAP). The coatings surface properties were analyzed with scanning electron microscope (SEM), atomic force microscope (AFM), and contact angle determinations. Electrochemical tests were performed in Afnor artificial saliva and evaluated by potentiodynamic polarization and electrochemical impedance spectroscopy. Based on these properties, comparisons of coatings performance were linked with the amount of deposited Ag. Increasing the Ag content led to the increase of the corrosion resistance and to the decrease of the forces exhibited on the surface. The hydrophobic character of the coating with the highest Ag amount could prevent thrombosis, thus suggesting its possible use for medical implants.
Highlights
Due to its biocompatibility and corrosion resistance, titanium (Ti) is known as the gold reference for implants in dentistry [1]
As a part of the novelty of the present manuscript, we propose to study the change of Ag-diamond-like carbon (DLC) film properties with increasing Ag amount, on the TiZr substrate, which is in extended use in dentistry, with the aim of identifying their suitability for implants in oral cavity applications after enhancing their properties
scanning electron microscope (SEM) images of all coated samples (Figure 1b–e) show that the high voltage anodic plasma (HVAP) coating process covered the surface of the substrate with a DLC film
Summary
Due to its biocompatibility and corrosion resistance, titanium (Ti) is known as the gold reference for implants in dentistry [1]. Alloying is a way to enlarge Zr fields of application, improving the material’s properties such as resistance to corrosion, mechanical behavior, and antibacterial activity. TiZr alloys are being investigated for implant applications due to the exceptional biocompatibility of both Ti and Zr combined with their better mechanical properties compared to pure Zr. The present manuscript’s aim is to enhance properties of this alloy using an Ag-DLC coating known from previous works as antibacterial and protective in bioliquids and to test the electrochemical stability and hydrophilic character of coated surface [6,7]
