Abstract

Al₂O₃-ZrO₂ composite coating was prepared on zirconium by micro-arc oxidation in an aqueous NaAlO₂-containing electrolyte. The coating is composed of α-Al₂O₃, tetragonal ZrO₂ (t-ZrO₂) and monoclinic ZrO₂ (m-ZrO₂), and firmly adherent to the substrate. The maximum hardness of the coating reaches 1630 Hv_{0.2 N}, and the friction coefficient of the coating against steel is as low as 0.115 at 200-1000 N loads under oil-lubricated condition. The structure and the formation mechanism of the Al₂O₃-ZrO₂ composite coating have been investigated.
