Microstructure and Property Study on Wear Resistant Composite Coating Produced by Ultrasonic-Assisted Argon-Arc Clad Injection

Abstract:

Ni60 self-fluxed alloy powder was coated on the surface of Q235 steel plate by the ultrasonic-assisted argon-arc clad injection technology, then TiC, TiN and Co powder were sprayed by the modificated injection device, and at the same time the powder was vibrated by the ultrasonic-assisted vibration device self-designed. The results shows that through the innovative technology, the wettability and dispersity of the reinforced phase are ameliorated, so as the elements diffusion and binding strength of the cladding layer with the matrix. The microhardness of the composite coating is 1.1 times than that of the coating without ultrasonic assisted, and 4.8 times than Q235 as the matrix. The wear resistance of the composite coating is 11 times than Q235, and 1.6 times than that of the coating without ultrasonic assisted.
