In order to enhance the tribological properties of Al-alloy moving parts, a Ni-Ti₃AlC₂ composite coating was applied onto the surface of ADC12 Al-alloy using high-pressure cold spraying technology. During the cold spraying process, spraying pressure and temperature are identified as two critical process parameters. In this study, while keeping the spraying pressure constant, the impact of spraying temperature on the microstructure, mechanical properties, and tribological behavior of the Ni-Ti₃AlC₂ composite coating/ADC12 Al-alloy was assessed. The findings indicate that with an increase in spraying temperature from 500 ^oC to 700 ^oC, there is a rise in plastic deformation degree of particles within the Ni-Ti₃AlC₂ composite coating leading to significantly improved bonding state between particles. This results in a 30% increase in coating bonding strength, a 60% decrease in porosity, a 14% increase in hardness, and a 41.7% reduction in coating wear rate. It is evident that appropriately elevating the spraying temperature may effectively enhance the density, mechanical properties and wear resistance of the coating. For spraying at 700 ^oC specifically, Ni-Ti₃AlC₂-700 ^oC exhibits the densest microstructure with no discernible pores or cracks which signifies superior mechanical properties as well as friction and wear characteristics. This can be attributed to the higher spraying temperature enhanced the striking velocity of composite particles, thereby improving deformability of Ni particles, thus the adhesion between Ni particles and Ti₃AlC₂ ceramic particles, as well as the adhesion between the coating and substrate may be significant enhanced. As a subsequence, the mechanical properties and frictional behavior of the coating can be substantially improved.
