利用专门设计制造的腐蚀磨损试验机，对在不同极化电位下双相不锈钢于硫酸介质中的腐蚀磨损行为和摩擦性能进行了试验研究，并且借助于扫描电子显微镜等对试样的磨损表面作了观察与分析．结果表明：采用适当的阴极保护可以有效地降低双相不锈钢的腐蚀磨损率；在钝化电位下的腐蚀磨损率比在自然电位和阴极保护电位下的都高；外加极化电位在阴极保护电位区或与动态腐蚀电位相当时，摩擦系数比自然电位下的低；钝化区的摩擦系数比自然电位下的高，可见此时钝化膜的减摩性能差；在钝化电位下当载荷高于１１．７Ｎ时，双相不锈钢的表面钝化膜遭受严重破坏
The corrosion and wear behavior and friction performance of duplex stainless steel in sulfuric acid medium under different polarization potentials were studied by means of specially designed corrosion wear tester. The wear surface of the specimen was analyzed by means of scanning electron microscope Observed and analyzed. The results show that: Corrosion wear rate of duplex stainless steel can be effectively reduced by appropriate cathodic protection; corrosion wear rate of passivated potential is higher than that of natural potential and cathodic protection potential; The coefficient of friction is lower than that under the natural potential; the coefficient of friction in the passivation zone is higher than that at the natural potential, showing that the anti-friction performance of the passivation film is poor at this time; when the load is under the passivation potential Above 11.7 N, the surface passivation film of duplex stainless steel suffers serious damage
