中文摘要:
      在硅酸钠和氢氧化钠电解液中利用微弧氧化技术在LY12铝合金表面生成陶瓷膜层。对膜层进行了SEM和TEM观察。对微弧氧化过程中电参数的变化规律进行了探讨,并分析了电参数对微弧氧化的影响。结果表明:在本实验条件下,用微弧氧化工艺在铝合金表面可制得致密的、厚度迭200 pcm的氧化膜,膜层与铝基体的结合层形成了纳米晶相。电参数对陶瓷层的厚度、硬度、粗糙度都有较大的影响。对微弧氧化膜层的钢球和陶瓷球磨损的对比可知,与钢球的磨损主要是粘着磨损,对陶瓷球的磨损主要是磨料磨损。
英文摘要:
      Ceramic coating was obtained by micro-arc oxidation on LY12 aluminum alloy in sodium silicate and sodium hydroxide electrolyte, and examined by SEM and TEM. The regulations of current and voltage were studied. Results show that a compact ceramic coating with thickness of 200p4m is obtained by micro-arc oxidation on Al surface, nano-crystalloid emerges in the joint that lies between the coating and Al. The results show that both the voltage and the current play very important roles in the thickness, hardness and surface roughness of the ceramic coating. Comparing the ceramic coating attrition tested by steel ball and ceramic ball, the attrition with the steel ball is adhesion attrition, and the attrition with ceramic ball is abrasive attrition.
