Enhancing Wear Resistance of Cryo Treated Cu-Be2 Alloy

Enhancing Wear Resistance of Cryo Treated Cu-Be2 Alloy In this investigation, the influence of cryogenic treatment on the tribological properties of Cu-Be2 alloy was investigated. Deep cryogenic treatment and shallow cryogenic treatment were applied to Cu-Be2 alloy. As-received (AR), shallow cryogenic treated (SCT) and deep cryogenic treated (DCT) Cu-Be2 alloy were used as pin material. AISI 4140 alloy steel hardened to 513 HV was used as disc. Wear test was carried out using pin-on-disc wear test set-up and the wear tracks were examined using Scanning Electron Microscope. Wear rate and coefficient of friction of the cryogenic treated sample were lower than that of the as-received sample.

Abstract

In this investigation, the influence of cryogenic treatment on the tribological properties of Cu-Be2 alloy was investigated. Deep cryogenic treatment and shallow cryogenic treatment were applied to Cu-Be2 alloy. As-received (AR), shallow cryogenic treated (SCT) and deep cryogenic treated (DCT) Cu-Be2 alloy were used as pin material. AISI 4140 alloy steel hardened to 513 HV was used as disc. Wear test was carried out using pin-on-disc wear test set-up and the wear tracks were examined using Scanning Electron Microscope. Wear rate and coefficient of friction of the cryogenic treated sample were lower than that of the as-received sample. Adhesive wear, plastic deformation and delamination of asperities were found to be the principal mechanism in the wear characteristics on the as-received as well as the cryogenic treated samples.
