Voltage-Dependent Evolution of Microstructure and Tribo-Mechanical Behaviour of Coatings Formed on CP-Ti from a Wollastonite–Hydroxyapatite Electrolyte by Micro-Arc Oxidation
Commercially pure titanium is widely used for load-bearing implants but its low surface hardness and high friction coefficient limit durability. In this work, calcium- and silicon-bearing coatings were deposited on CP-Ti (VT1-0/ASTM Grade 2) by micro-arc oxidation (MAO) in an aqueous electrolyte of 30 wt.% H3PO4, 60 g/...
