用两种典型的磨料(长石和石英沙),试验了不同含水量对塑料和钢的磨损的影响。指出了在磨料磨损过程中含水量是个敏感因素,分析了水在磨料磨损中的三个主要作用:(1)对砂粒的粘结作用;(2)摩擦氧化作用;(3)水膜的润滑作用。论述了磨料磨损过程中磨损机理的转变。此外,还试验了不同颗粒度和滑动速度对磨损的影响,最后提出了这些试验结果在实际应用中的可能性。 Two typical abrasives (feldspar and quartz sand) were used to test the effect of different water contents on the wear of plastic and steel. It is pointed out that water content is a sensitive factor in abrasive wear process. Three major functions of water in abrasive wear are analyzed: (1) bonding to sand; (2) frictional oxidation; (3) lubrication of water film effect. Discusses the change of wear mechanism in abrasive wear process. In addition, the effects of different particle sizes and sliding velocities on the wear were also tested. Finally, the feasibility of these test results in practical applications was proposed.
