Study on High Temperature Wear-Resistant Properties of the as-cast CoCrW Alloys

Full Text(PDF, 1369KB)

Author: Feng Li, Jiajia Li, Zhenhua Dan

Abstract: The microstructure and the wear-resistant properties of the as-cast CoCrW alloys at different temperatures were investigated by combining XRD, SEM, EDS and high temperature friction and wear tests. The results showed that the microstructure of the as-cast CoCrW alloys was composed of M23C6, M6C and γ-Co phases. The block-shaped carbides with different sizes were distributed into γ-Co matrix. The friction coefficients and wear loss of the alloys gradually decreased with the increase in temperature and the wear resistance of the alloys was the best at 600℃. When temperature was above 800℃, the wear resistance of the alloy became worse due to oxidation. Further analysis indicated that the mechanism that controls the wear-resistant property of the CoCrW alloys at different temperatures was the interaction of abrasive wear, spalling and oxidation wear.

Keywords: CoCrW Alloys; Microstructure; High Temperature Wear-resistant Property
