三种腐蚀磨损试验机与两种不锈钢腐蚀磨损性能的研究

腐蚀磨损现象广泛发生在石油，化工，煤矿和电力等工业领域的机械设备中，是造成材料流失和设备失效的主要原因之一，尽管这种磨损现象越来越引起了人们的关注，并且已经对其进行了一些试验研究，然而由于所用的试验设备本身就存在着一定程度的腐蚀磨损，因而很难保持其长期稳定的工作状态，而且目前国内外都还没有定型的专用设备出售．针对这种情况，设计研制了３种可以用于不同研究目的并能长时间稳定工作的腐蚀磨损试验机──稳态

Studies on Three Types of Corrosive Wear Testers and Corrosive Wear Behavior of Stainless Steels

Corrosive wear,which is widely found in mechanical equipment of oil,chemical,mining and electrical industries,is one of the main reasons which induce material loss andequipment failure,Studies on corrosive wear have been earried out recent years,but there are manyproblems in corrosive wear testers and no special testers for experiments of corrosive wear.So threetypes of corrosive wear testers,which had good operating performance and could be used fordifferent purpose study,have been designed and man ufactured in our laboratory.The steady testercan be used not only for evaluating corrosive wear properties of metals in different corrosivemediums but also for studying mechanism of corrosive wear.Transient information of metal surfacebeing scratched in different corrosive mediums can be obtained from the transient tester.The slurryerosion tester can be used for evaluating corrosive wear property of metals in simulative conditions,this is important to mechanism study and material selection. Corrosive wear behavior of AISI 316Land dupiex stainless steel was studied by using these testers.The results indicate that these testerspossess good operating performances and can be used for studying corrosive wear systematically.
