Abstract

Transition metal oxide MoO₂ was in situ introduced into a γ/NiMo alloy by laser melting deposition (LMD) process. High-temperature phase stability of the MoO₂ was studied by aging at 1100 °C for 200 h and effect of the MoO₂ on high-temperature wear resistance of the alloy was also investigated under sliding wear test conditions. Results showed that the MoO₂ had a uniform distribution, high hardness and excellent high-temperature phase stability. The MoO₂ reinforcing phase played a key role in improving wear resistance of the alloy so that soft abrasion became dominant wear mechanism of the alloy under high-temperature sliding wear test conditions.
