【摘要】：為了改善金屬表面的摩擦學(xué)特性,開(kāi)發(fā)了研磨拋光微孔表面織構(gòu)技術(shù),研究了載荷、研磨顆粒粒徑對(duì)表面織構(gòu)參數(shù)(微孔表面密度、面積密度、孔徑以及表面粗糙度等)的影響。結(jié)果表明:當(dāng)載荷從0.007 3~0.023 2 MPa變化時(shí),在相同的研磨時(shí)間周期內(nèi),單位面積微孔數(shù)量增多,微孔孔徑增大,表面粗糙度也隨之增加,微孔面積密度從5.51%增加至10.07%;當(dāng)粒徑從0.5~50μm變化時(shí),單位面積微孔數(shù)量迅速減少,微孔孔徑明顯增大,表面粗糙度增加,而微孔面積密度則隨著粒徑的增加而下降,當(dāng)磨粒粒徑大于20μm時(shí),研磨顆粒會(huì)對(duì)工件表面產(chǎn)生亞損傷。
[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.
