应用一种恒力式滚压工具,依据Box-Behnken中心组合设计原理,以车削进给量、滚压力和滚压次数为自变量,以在SRV IV实验机上实现的100℃下的无润滑条件和润滑条件下的微动磨损体积为响应值,对6061铝合金进行滚压后的微动实验,推导出了非平面微动磨损体积的计算公式,并对微动实验中的摩擦系数、试样初始表面粗糙度和磨斑表面形貌进行了分析.结果表明：在无润滑条件下,滚压不能明显提高微动磨损性能;而在润滑条件下,滚压试样的平均微动磨损体积比未滚压试样的减少21.5%;在最优滚压参数（切削进给量为0.10mm/r,滚压力为60N,滚压1次）下,可以得到最小的微动磨损体积,仅为未滚压试样平均微动磨损体积的46.2%.

Based on the Box-Behnken combination design,a force-constant burnishing tool was used to burnish AL 6061 specimens,followed with fretting experiments on a SRV IV test machine.During the burnishing,the cutting feed,the burnishing force and the number of passes were selected as the independent variables,and the fretting wear volumes of AL 6061 under lubricated and dry conditions at 100 ℃ after the burnishing were used as the responses.A formula calculating the fretting wear volume of non-planar specimen was deduced,and the fretting friction coefficient,the initial surface roughness and the surface morphology of wear scars were analyzed.The results indicate that,under dry conditions,the burnishing has no obvious influence on the fretting wear behaviors of AL 6061,and that,under lubricated conditions,the average fretting wear volume of the burnished surface decreases by 21.5%,as compared with that of the un-burnished surface.Moreover,it is found that,in the optimal burnishing conditions,that is,burnishing at a cutting feed of 0.10 mm/r and a burnishing force of 60 N with one pass,the fretting wear volume reaches the minimum,which is only 46.2% of the average fretting wear volume of the un-burnished surface.
