摘要
对近１０年来国内外在磨粒侵蚀研究的进展作了综合介绍与评述，重点论述了液体介质的速度、介质中颗粒的浓度、颗粒尺寸以及其它因素对高分子材料和金属材料的磨粒侵蚀率的影响，在此基础上，讨论了磨损率的准理论方程。介绍了高子分材料、金属材料、复合材料和陶瓷以及水力旋流器锥套磨粒侵蚀的磨损机理，并提出了今后磨粒侵蚀研究中的几个值得重视的研究方向。
The abrasive erosion is one of the usual wear modes, which occurs in a number of hydromachines and oilfield equipment handling granlar materials. In order to promote the development of study on abrasive erosion, a survey on research of abrasive erosion during the past decade is presented.The influence of the flow velocity, particle size, particle concentration and other factors on the abrasive erosion rate for the polymeric materials and metallic materials are analyzed. Based upon these studies, the quasi-theoretical wear, rate equations, are given. The w.ear mechanisms for polymers,metals, composites, ceremics and the cone of hydrocyclone are investigated. Moreover, some suggestions about the further study on abrasive erosion are proposed.
