测定了ＡＩＳＩ３０４不锈钢在不同Ｃｌ－浓度的１ｍｏｌ／ＬＨ２ＳＯ４溶液中的静态腐蚀率及腐蚀磨损率．同时利用单摆冲击划痕实验机测定了不同条件下材料表面划痕的长度随冲击能耗的变化及其比能耗值，证明了随Ｃｌ－浓度的增加，材料表面的比能耗下降，即腐蚀及腐蚀磨损作用加剧原因系材料表面变脆．
The static corrosion rate and corrosion rate of AISI 304 stainless steel in 1 mol / LH 2 SO 4 solution with different Cl- concentrations were measured. At the same time, the pendulum impact scratch test machine was used to determine the change of impact energy and the specific energy consumption of scratches on the surface under different conditions. It was proved that the specific energy of the material surface decreased with the increase of Cl- concentration, Namely corrosion and corrosion wear play a role in the material surface becomes brittle.
