摘　　要：采用等离子喷涂法在钛合金基体上制备了纳米氧化锆陶瓷涂层,采用微弧氧化法在锆合金基体上制备了氧化锆陶瓷膜层。通过摩擦磨损试验研究了纳米陶瓷涂层和微弧氧化膜层的摩擦磨损性能。结果表明:在往复滑动磨损条件下和两种载荷水平下,两种涂层均呈现相同的耐磨性规律;在较大载荷下,微弧氧化膜层的磨痕深度较大,即纳米ZrO2陶瓷涂层的耐磨性优于微弧氧化陶瓷膜层。The nano-structure ZrO2 ceramic coatings were prepared on the surface of TC4 by plasma sprayed technique.The ZrO2 ceramic coatings were prepared on the surface of Zr alloy by MAO. The wear characteristics of different coatings were investigated by friction-wear test. The results demonstrate that under the conditions of reciprocating sliding wear and two kinds of load level, two kinds of coating presents the same wear regularity. Under large load, the grinding crack depth of micro-arc oxidation coatings is larger, then, the wear resistance of nano ZrO2 ceramic coating is better than that of micro-arc oxidation ceramic coating.
