<正> 腐蚀磨损是指摩擦过程中材料与介质发生化学或电化学反应并产生材料流失的磨损现象。在侵蚀性介质中工作的摩擦副如各类泵及阀门的密封面等部件往往因腐蚀及磨损的双重作用而过早失效,因此这类问题很受人们重视。 Uhlig对腐蚀与微动损伤的相互作用进行过讨论。等对某些高合金钢的府蚀磨损性能作过较系统的评价,并建立了实验设备。欲了解材料的腐蚀磨损性能,除了要弄清楚它在介质中的化学及电化学行为外,还要了解受机械力作用时材料表面或表面膜的变形及流失过程。更主要的是两者间的关系。因此,Kim及Bhattacharyya研究了不锈钢在NaCl介质中磨损及摩擦参数对电化学行为的影响。为了研究腐蚀磨损的瞬态过程而建立物
The corrosive wear behaviour of pure Ni, Ti-6Al-4V, Al alloy, medium carbon-steel and 304 stainless steel was examined by means of pin-plate wear device and potentiostat in 1 N H_2SO_4 and 1％ NaCl solution. The effect of load and slide speed on polarized curves and scratch traces were measured. It was found that the formation of a passive film on the alloy surface such as stainless steel could retard or promote the corrosive wear, while wear rate was enhanced on fresh surface of carbon steel in corrosive medium.
