| Abstract |
| The wet sliding wear tests were performed on A356/20vol.% SiCp composites against semi-metallic pad materials. The samples were tested by pin-on-disc wear test equipment. The wet wear properties of A356/20vol.% SiCp against semi-metallic pad have exhibited good results with low wear rate up to 700N applied load and 4.0m/s sliding velocity and low friction coefficient in the range of 0.17~0.23. In addition, the wear properties under wet sliding conditions have been compared with those under dry sliding conditions. Wear behavior has been examined through the observations and analysis of the worn surface, worn subsurface and wear debris. It is revealed that thin lubricant films are formed on the worn surface to reduce the wear rate in the low applied load and/or sliding velocity conditions. In addition, platelike worn debris has been formed on the worn surface with increasing the applied load and/or sliding velocity due to the plastic flow and increase of temperature on top of the worn surface. |
