滚压对碳钢微动磨损性能的影响
Effect of burnishing on fretting wear behaviors of carbon steel
摘要
Abstract
In order to improve fretting wear properties of the carbon steel, the burnishing processes with different parameters were introduced to the surface treatment of 1045 steel specimens. The surface roughness, microhardness and the thickness of hardening layer treated by different burnishing processes were evaluated using surface topography device, vickers microhardness tester and scanning electronic microscopy (SEM). In addition, the fretting wear characteristics of samples with different burnishing parameters were investigated using SRV Ⅳ tester. The results show that thick hardening layer is generated on the surface of the steel samples by burnishing process. The surface roughness reduces and the microhardness increases significantly. The friction coefficient and wear loss are decreased obviously after burnishing process. Moreover, the wear mechanisms of untreated specimens are mainly adhesive wear and fatigue wear, whereas the treated specimens are mainly damaged by abrasive wear accompanied with slight fatigue spalling. The burnishing parameters have an obvious effect on steel surface properties and fretting wear characteristics. And the burnished 1045 steel specimens have better wear resistance.关键词
