摘要: 本文介绍用自制的销环式腐蚀磨损机研究18-8不锈钢在1NH_2SO_4介质中不同电位区的腐蚀磨损行为。结果表明载荷与腐蚀磨损间仍然存在线性关系。阴极极化区内腐蚀受到抑制,单纯磨损作用造成的材料流失量不大;过钝化区内腐蚀与磨损协同作用而加速材料流失:钝化区内由于磨损导致钝化膜破裂,且载荷越大、电位越正材料流失越严重,故一般的阳极保护法不适用于腐蚀与磨损并存的情况。

Abstract：The corrosive wear performance of 304 stainless steel in sulfuric acid was determined in 1N H_2SO_4 at different polarization potentials by means of a pin-disc device. The linear relationship, with different slopes between corrosive wear and loads was confirmed. It is suggested that the removal of material in cathodic polarization region only results from mechanical wear, therefore linear relationship exists with a small sloper the synergy of corrosion and wear accelerates the removal of material in over-passive region, in which high linear slope appears; in passive region the breakdown of passive film results from shear stress, the higher of load and the more positive of potential, the more removal of material will be. So anodic protection is not suitable for corrosive wear of alloys.
