Abstract
Titanium (Ti) and its alloys are mostly utilized for orthopedic and dental applications on account of its excellent corrosion resistance, good formability, excellent fatigue strength and lower modulus of elasticity. As Ti is bioinert, it’s not satisfactory for long-term clinical applications and can't attach to living bone straightforwardly at the beginning phase after implantation into a human body. With an end goal to improve implant-cell connection, many surface alterations techniques have been examined in the recent past to quicken osseointegration process and upgrade surface topography with the tissue of host. Plasma electrolytic oxidation (PEO) process likewise called micro-arc oxidation (MAO) can be utilized successfully for surface alteration of Ti and its alloys. PEO is an electrochemical surface modification technique to create defensive oxide coatings on light metal, for example, titanium, aluminum and magnesium. PEO is a basic, single-step surface modification strategy used to create coatings on Ti and its alloys for orthopedic and dental applications. Desired coating properties can be obtained by changing process parameters of PEO process, for example, electrolyte composition, frequency, processing time, duty cycle and applied voltage. Electrolyte concentrations is a significant factor to impact growth mechanism of coating. It has been observed that, porosity decreases as the PEO current density increases due to the higher rate of ionic current and sealing effect on the micro size pores. It was seen that for better wear resistance, temperature during coating should be kept at lower values. It was likewise seen that the safest coating to erosion was acquired in the oxidized titanium alloy specimen deposited at 500 Hz with 30% duty cycle by PEO. This review article is focusing on surface modification of Ti and its alloy by plasma electrolytic oxidation process and process parameters effects on substrate characteristics.
