Tribological properties, phase compositions and wear mechanisms of laser cladding NiAl coating were investigated from room temperature to 1000 °C under air atmosphere environment. The results showed that a glaze layer composed of NiO, Ni2O3, Al2O3and NiAl2O4phases as well as Ni3Al phase were formed on worn surface under high temperature, which act as a solid lubricant and anti-wear material improving the tribological properties of NiAl coating at elevated temperatures. The wear mechanism is dominated by abrasive wear below 500 °C, and transforms to plastic deformation and adhesive wear at 500 °C up to 700 °C and oxidation wear at 900 °C and above, owing to formation of new oxide phase during tribochemical reaction.
