腐蚀磨损中几种测量纯机械磨损分量方法的比较

MCOMDARATIVE MEASURMENTS OF WEAR LOSS COMPONENT INDUCED BY MECHANICAL ACTION IN CORROSIVE WEAR PROCESS

研究了腐蚀磨损交互作用量中纯机械磨损分量的测量方法，采用暂态腐蚀磨损试验机，并将试样分别置于单纯的蒸馏水中，或置于蒸馏水后同时加以阴极保护或添加缓蚀剂的三种条件下进行测量，并用空气中的磨损量作对比。３种方法得到的纯机械磨损量和摩擦系数接近，可作为腐蚀磨损交互作用中各分量的计算，但在蒸馏水中因纯铁和１０４５钢有腐蚀仍不宜使用。

The methods for measuring the component induced only by mechemical action amoung the while weight loss in a corrosive wear process.The methods used include three measurements in disstilled water without and with cathodic protection or adding inhibitor. The weight loss obtamed by the above methods were carefully compared with that in air. The results show that the mechanical wear loss components and friction coefficients obtained by the three methods are close to each other and can be used to calculate the various wear conponents in the study of the mutual effects of corrosion and wear, but the measurements in distilled water for pure iorn and 1045 steel are not recommanded due to their corrosion.
