摘要
表面光洁度对部件的大部分功能性能有重要影响,如疲劳强度、耐磨性和耐腐蚀性。这就产生了研磨、珩磨和抛光等工艺。抛光是一种精细的精加工操作,涉及表面层的冷加工和塑性变形,以提高零件的表面完整性和功能实用性。研究了进给量、速度、力、球径和润滑剂等抛光参数对HSLA双相钢试样表面粗糙度和耐蚀性的影响。结果表明,抛光参数对表面粗糙度和耐蚀性有显著影响。关键词:硬度;抛光;的阶乘设计;临界温度东非科学杂志Vol. 2 (2) 2008: pp. 164-169
Investigations on the Effect of Ball Burnishing Parameters on Surface Roughness and Corrosion Resistance of Hsla Dual - Phase Steels
Surface finish has a vital influence on most functional properties of a component, such as fatigue strength, wear resistance and corrosion resistance. This has led to processes such as lapping, honing, and burnishing. Burnishing is a fine finishing operation involving the cold working and plastic deformation of surface layers to enhance the surface integrity and the functional utility of a component. This study has been carried out to establish the effect of burnishing parameters, i.e. feed rate, speed, force, ball diameter and lubricant on surface roughness and corrosion resistance of HSLA dual phase steel specimens. The result indicates that burnishing parameters have a significant effect on surface roughness and corrosion resistance.
