摘要
为改善轴向柱塞泵配流副的摩擦磨损性能,采用光刻-电解工艺,对配流副进行织构化,在配流副摩擦磨损试验机上进行试验研究.结果表明：织构化配流副能够有效减小摩擦因数,平均磨损截面面积和表面粗糙度的变化值都小于无织构配流副,不同于无织构配流副形成了比较严重的黏着磨损,微凹坑直径为100-300μm时磨损相对更小,配流副只产生磨粒磨损,此时平均磨损截面面积为无织构配流副试件的4.54%-7.14%.摩擦因数和平均磨损截面面积间有着良好的相关性.
To improve the friction and wear performance of port plate pair of axial piston pump,textured port plate pair were obtained by lithography and electrolysis technique,and the tests were carried out on the port plate pair＇s friction and wear tester.The results show that the textured port plate pairs can effectively reduce the friction coefficient,and their average wear sectional area and surface roughness are much less than the untextured ones.More severe adhesive wear is formed on the untextured port plate pair and only more serious abrasive wear on the textured ones with diameter of micro-dimples ranging from 100μm to 300μm,whose average wear sectional area was 4.54%-7.14% of untextured ones.There exists a good correlation between friction coefficient and average wear surface sectional area.
