Özet

The addition of 10 wt% Mo encouraged a eutectic reaction to form Co₆Mo₆C complex carbide and Co₃Mo intermetallic in addition to Cr₂₃C₆ while causing solid solution hardening of the Co-rich dendritic matrix in the microstructure of the PTA deposited Stellite 12 coating. The addition of molybdenum not only imposed a higher hardness but also enhanced wear resistance. Under oxidation dominated wear conditions (500 and 700 °C), the addition of molybdenum provided a remarkable increase in wear resistance in comparison to the lower temperatures (RT and 300 °C), due to the development of a protective oxide film on the worn surface.
