| 摘 要： | 研究了氧化铝（F99.7)对氧化锆增韧氧化铝（ZTA）摩擦副在盐酸，氢氧化钠介质中的摩擦学特性，用扫描电子显微镜（SEM）观察了磨损表面形貌，结果表明，该摩擦副在盐酸中的摩擦因数比在据氧化钠中的小；但线磨损总量则相反，在盐酸中的线磨损总量要比在氢氧化钠中的大，磨损产生的原因可能是由于基体材料和介质之间发生摩擦化学反应而引起的。

| Abstract: | Tribological properties of alumina-zirconia toughed alumina (ZTA) rubbing pairs were investigated in the solution of hydrochloric acid (HCI) and sodium hydroxide (NaOH) . The worn surfaces were examined by using scanning electron microscopy (SEM) . The experimental results showed that the friction coefficient was lower in HCI than that in NaOH, but the amount of linear wear was higher in HCI. The mechanism of wear was perhaps that some chemical reactions took place between ceramic substrates and interfacial media. |
