随复合材料硬度的增加，磨损机理由严重磨粒磨损向轻微磨粒磨损转变。
Wear mechanism transferred from server abrasive to adhesion with the increasing of hardness of the composites.
笔者对磨辊表面进行激光束淬火处理，以提高磨辊的表面硬度，增强磨辊的抗磨粒磨损性能，从而达到延寿的目的。
Author used laser beam to quench the surface of the ore milling roller, so that increase its surface hardness and improve its wear resistance properties, and prolong its service life.
当w（WC）大于50%时，WC的加入使喷熔工艺性能变得极差，喷熔层的硬度和耐低应力磨粒磨损性能降低。
When WC content is more then 50%, spray-fusing technological property becomes worse, hardness of sprayed coating and low-stress abrasive particle wear resistance are weaken.
对于较低硬度的工件表面，采用蜡敷磨粒的磨料液可缩短抛光时间和提高抛光的表面精度。
For the lower hardness of the surface, use slurry abrasive with wax-coated particles can reduce the polishing time and improve the accuracy of the surface polishing.
