Abstract The cylinder/valve plate friction pairs were proven to be subjected to wear and failure in axial piston pumps. The synergy method of surface micro-texturing and wet micro-blasting was put forward to enhance the tribological performance of H62 brass/38CrMoAl conjunctions. Tribological tests configured with disk-on-disk motions were performed to obtain the friction coefficient of flat, micro-textured, wet micro-blasted flat and wet micro-blasting micro-textured samples. The friction coefficient of wet micro-blasted flat samples was lower than that of merely flat specimens. The friction coefficient of wet micro-blasted flat and wet micro-blasting micro-textured samples was reduced with the increment of blasting time. The wear mechanisms of wet micro-blasted flat and wet micro-blasting micro-textured samples were distinct from that of flat and micro-textured samples.

采用各种制造方法的 H62 黄铜的工艺-表面形貌-摩擦学性能关系

摘要 轴向柱塞泵的气缸/阀板摩擦副已被证明会受到磨损和失效。为了提高H62黄铜/38CrMoAl结合物的摩擦学性能，提出了表面微织构和湿式微喷丸协同处理的方法。进行了配置有盘对盘运动的摩擦学测试，以获得平面、微纹理、湿微喷平面和湿微喷微纹理样品的摩擦系数。湿微喷平面试样的摩擦系数低于纯平面试样的摩擦系数。湿式微喷平面和湿式微喷微纹理样品的摩擦系数随着喷砂时间的增加而降低。
