Sliding Wear Behavior of Cryogenic Treated Copper Beryllium Alloy

Abstract:

In this study, the effect of Shallow Cryogenic Treatment (SCT) on the wear behavior of copper beryllium alloy was investigated. The material is subjected to shallow cryogenic treatment to – 80 °C and wear study was conducted on a pin on disc apparatus. The Shallow Cryogenic treated and untreated copper beryllium alloy pins were used against hardened AISI 4140 steel disc. The micro-structural examination was carried out using optical microscope. The hardness was measured using Rockwell hardness tester. The wear track was studied using optical microscope. Microstructure study indicated that the grains of shallow cryogenic treated samples are finer than that of untreated sample. Hardness of the cryogenic treated sample is higher than that of the untreated sample. The wear resistance of cryogenic treated copper beryllium alloy has improved compared with untreated sample.
