从腐蚀磨损速率、钝化膜承载能力以及点蚀与腐蚀磨损的关系等方面，研究Ｃｌ~－对不锈钢在Ｈ_２ＳＯ_４溶液中轻载下的腐蚀磨损行为的影响．在自然电位下，Ｃｌ~－对腐蚀磨损存在一临界载荷，低于此载荷腐蚀磨损速率略有降低；高于此载荷，腐蚀磨损率增加．轻载下磨痕内的点蚀坑较多而深，高载下点蚀坑少且浅．在钝化区，Ｃｌ~－下降低钝化膜的承载能力，使腐蚀磨损率增加．
The effects of Cl~- on the corrosive wear behaviour of stainless steel in H_2SO_4 solution were studied via the corrosive wear rate, the load bearing capacity of passive film and the relationship between pitting and corrosive wear. There is a critical load at natural potential, below which the corrosive wear rate is slightly lowered by Cl~-, but when the load is higher the corrosive wear rate increases with the increase in Cl~-. There are more pits at low load than at high load in the wear tracks and the pits is deeper at low load than at high load. The load bearing capacity is lowered by Cl~- at passive region and then the corrosive wear rate increased.Correspondent: HUANG Yanliang,(Institute of Metal Research, Chinese Academy of Sciences,Shenyang 110015)
