Plasma Electrolytic Oxidation Ceramic Coatings on Zirconium (Zr) and Zr-Alloys: Part-II: Properties and Applications

A plasma electrolytic oxidation (PEO) is an electrochemical and eco-friendly process where the surface features of metal substrate are changed remarkably by reactions accompanied micro-discharges. stiff, adhesive, conformal oxide layer on Zr Zr-alloy substrates can be formed applying PEO process. The review describes recent progress various applications functionality coatings in light increasing industrial, medical, optoelectronic demands for production advanced coatings. Besides, it explains how coating address concerns about employing protective long-lasting with a remarkable biocompatibility broad excitation absorption range photoluminescence. general overview parameters provided, some information related to biological conditions, under which, expected function. focus explain improved tailoring After that, corrosion wear performance described recognizing that lead formation outstanding extreme loading conditions corrosive environments. Finally, future outlook suggested research areas outlined. emerging derived from paramount considered practical properties including bioactivity, protection, photoluminescence
