  • 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 100 μm to 300 μm, 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.
