摘要

Friction and wear is one of the most difficult problems that must be tackled properly in the research and development of tap water or sea water hydraulic power transmission and control technology, owing to the strong corrosion and insufficient lubricity of pure water in contrast with mineral oil. Materials that demonstrate excellent anti-wear property can not applied to water hydraulic components since those materials, which in general are carbon steel, aluminum or copper alloys, cannot resist the corrosion by water, especially seawater. Therefore, much attention must be paid to the selection of appropriate materials that can meet the special requirements of the components such as slipper, swashplate, and cylinder bore or lining, flow distribution plate, etc. Since there are quite few experimental results available that can be consulted, some fundamental test should be carried out before some certain materials are adopted in design. Simple comparison of the physical and mechanical properties of some engineering plastics shows that polyetheretherketone, abbreviated as PEEK, possesses superior comprehensive properties such as high stiffness and hardness, low water absorption ratio, prominent anti-wear capability and chemical stability. There is no denying that PEEK is one of the most important candidate materials for frictional components. In this paper, on the test rig that simulates the interaction between slipper and swashplate, piston and cylinder, the tribological features of PEEK as slipper and cylinder bore lining materials were tested. Some detailed experimental results are presented, and further explanation is given with the aid of microstructure analysis of the worn surfaces. The swashplate material includes 2Cr13 which was heat treated, stainless steel whose surface is modified by plasma sprayed ZrO_2·MgO and laser melted alloy respectively. It is found that the wear of PEEK is the least when its counterpart is laser-melted alloy, and the wear is most when its counterpart is plasma sprayed ZrO_2·MgO.
