细磨料 meaning in Chinese

finer abrasive

The results show that the composites were more wear resistant than the matrix , contributing to the " volume effect " and " size effect " , the wear resistance increases with the particle content and size . the composite shows better wear resistance than high chromium cast iron material especially in low load and fine abrasive test condition . the results also indicate that the composite strengthened by ageing treatment was more wear resistant than as - cast composite
磨损试验结果表明，铸造碳化钨颗粒增强cu - ni - mn合金基复合材料具有比较高的抗磨料磨损能力，而且其耐磨性随着铸造碳化钨颗粒体积分数及尺寸的增大而提高，表现出了强烈的“体积效应”及“尺寸效应” ，尤其是在低载荷、细磨料磨损条件下，复合材料表现出更好的而寸磨性，即使与高铬铸铁( cr28 )相比也有很大程度的提高。
