摘要:

The interaction between oxidation and frictional load can greatly deteriorate the performance of ceramic -metal composites. In this work, we used WC-Co cermet as a representative of ceramic-metal composites to study its wear failure behavior and protection effectiveness. It is found that a transition of wear mech-anism from mechanical wear to oxidative wear occurs with increasing temperature. The addition of zir-conia can significantly improve the anti-oxidation performance and load-bearing capacity of the cermet under the frictional load. This is mainly attributed to the modulation of the tribo-oxide layer constitu-tions and changes in surface morphology. The zirconia component facilitates the formation of a dense protective oxide layer and reduces the content of brittle oxides on the worn surface. Based on the under-standing of the temperature-and oxidation-induced compositional and microstructural evolutions at the sliding contact surface and subsurface, a promising approach is proposed for developing ceramic-metal composites with high wear resistance and anti-oxidation capability.(c) 2023 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science & Technology.
