【摘要】：为了改善金属表面的摩擦学特性,开发了研磨抛光微孔表面织构技术,研究了载荷、研磨颗粒粒径对表面织构参数(微孔表面密度、面积密度、孔径以及表面粗糙度等)的影响。结果表明:当载荷从0.007 3~0.023 2 MPa变化时,在相同的研磨时间周期内,单位面积微孔数量增多,微孔孔径增大,表面粗糙度也随之增加,微孔面积密度从5.51%增加至10.07%;当粒径从0.5~50μm变化时,单位面积微孔数量迅速减少,微孔孔径明显增大,表面粗糙度增加,而微孔面积密度则随着粒径的增加而下降,当磨粒粒径大于20μm时,研磨颗粒会对工件表面产生亚损伤。
[Abstract]:In order to improve the tribological properties of metal surface, a technique of grinding and polishing microporous surface texture was developed. The effects of load, abrasive particle size on surface texture parameters (micropore surface density, area density) were studied. Effect of pore size and surface roughness etc. The results show that when the load varies from 0.007 to 0.023 MPa, the number of micropores per unit area increases and the surface roughness increases at the same grinding time period. The area density of micropore increased from 5.51% to 10.07. When the particle size changed from 0.5 渭 m to 50 渭 m, the number of micropores per unit area decreased rapidly, the pore diameter increased obviously and the surface roughness increased, while the area density of micropore decreased with the increase of particle size. When the particle size is more than 20 渭 m, the abrasive particle will cause subdamage to the workpiece surface.
