一、前言磨粒以一定的速度和角度撞击材料表面,使材料失去,这种磨损方式称为粒子撞击磨损。在某些工况条件下如风扇磨、泥浆泵、粉料气动输送管道的拐弯处、沙漠地带的飞机和直升飞机等都会迂到这类磨损。国外把这种磨损称作“侵蚀(erosion)”,早在四十年代就开始了这方面的研究,其中1.Finnie、Sheldon、Bitter、Tilly、Hutchings、Winter、Jahanmir、Ruff等人先后研究了各种因素对粒子撞击磨损的影响,包括有粒子的形 First, the introduction of abrasive particles to a certain speed and angle impact on the surface of the material, the material loss, this wear is called particle impact wear. In some operating conditions, such as fan grinders, mud pumps, pneumatic pneumatic conveying pipe corners, desert areas of the aircraft and helicopters, etc. will be worn to such wear. Abroad referred to this kind of abrasion as “erosion”, which began research in this field as far back as the 1940s, in which 1.Finnie, Sheldon, Bitter, Tilly, Hutchings, Winter, Jahanmir, Ruff and others successively studied Various factors on the impact of particle impact wear, including the shape of the particles
