Study on the Abrasive Wear of Chromeplate Piston Ring and Cylinder Jacket Made by Different Materials

Abstract

The abrasion of piston rings/tribomate pairs of cylinder jacket has great damage to engine, which can shorten the life of piston rings and cylinder bore, decrease the power of engine, enlarge the amount of oil, and release more pollution. Take a research of abrasive wear of piston ring and cylinder jacket made by different materials, will create a positive influence on extending the life of engine. This paper takes the SRV friction and wear tester, conducts the research on the abrasive ability of the three tribomate pairs (Cr plated piston ring and P-B, Cu-Cr-Ni-Mo and bainite cylinder bores) under the condition that there lies a certain amount of quartz sand in the lubricant and find that the hardness, intensity and tenacity of tribomate materials can have influence on its capability of resisting abrasion.
