It was found the wear volumes of cera -mits and east irons were reduced in water Lubrication. Wear volumes of grey easts were greater than that of ductile iron when matched with Al2O3, and the wear volumes of steel were the greatest. The wear volumes of Al2O3 against east iron was greatly smaller in air than against steel.

结果表明：蒸馏水润滑下Al2O3及铸铁的磨损体积均小于在干磨擦条件下；在同一润滑条件下，钢的磨损体积大于铸铁磨损体积，球墨铸铁磨损体积最小；陶瓷Al2O3磨损体积在干摩擦时与铸铁配副时比与钢配副时要小得多。
