摘要

A nanoplate-like α-Al ₂ O ₃ out-layered Al ₂ O ₃ -ZrO ₂ coating was fabricated on Zr substrate by micro-arc oxidation (MAO). The structure, formation mechanism, anti-wear property and aging behavior of the coating were explored. The obtained results show that the coating is composed of Al ₂ O ₃ and ZrO ₂ ; the amount and crystallinity of Al ₂ O ₃ increase gradually from inner layer to the coating surface; monoclinic ZrO ₂ (m-ZrO ₂ ) and tetragonal ZrO ₂ (t-ZrO ₂ ) are both present in the coating, and the ratio of t-ZrO ₂ /m-ZrO ₂ increases with closing to the coating surface by a "constraint" mechanism of Al ₂ O ₃ ; the coating surface mainly consists of nanoplate-like α-Al ₂ O ₃ , and a small amount of nanocrystallized m- and t-ZrO ₂ . The superimposition of α-Al ₂ O ₃ growth unit on {0 0 0 1} face should be prohibited by PO ₄ ^3- during the MAO process, resulting in the formation of nanoplate-like α-Al ₂ O ₃ on the coating surface. Compared with pure Zr, the coating shows noticeable improvement in wear-resistance. For aging behavior, although more t-ZrO ₂ in the coating is transformed to m-ZrO ₂ with increasing aging time, wear loss increases slightly. It indicates that the nanoplate-like α-Al ₂ O ₃ out-layered Al ₂ O ₃ -ZrO ₂ is a potential coating for articular head replacement.
