用工业纯铁,不同热处理的65Mn钢以及高铬白口铁试样在销盘式磨粒磨损试验机上进行磨损试验。用动态应变仪-磁带记录器-数据处理计算机仪器组配记录、测定了磨料磨损过程中,磨粒和试样磨损表面间的磨损作用力,研究了磨料粒度、载荷、试样材料及硬度对磨损作用力、磨损量的影响;分析了随磨料粒度的变化,磨损机制变化的规律,进一步探讨了磨损机理。 Using industrial pure iron, different heat-treated 65Mn steel and high-chromium white iron samples were tested for wear on pin-on abrasive wear testers. The dynamic strain gauge-tape recorder-data processing computer was used to record the wear forces between the abrasive grains and the worn surface of the specimen. The effect of abrasive grain size, load, sample material and hardness Wear force and wear amount. The regularity of the change with the abrasive grain size and wear mechanism was analyzed, and the wear mechanism was further discussed.
