Effect of magnetic-electric-ultrasonic fields on microstructure and properties of Ni60A laser cladding coating
Ni60 coating is prepared utilizing laser cladding on 45 steel assisted by magnetic-ultrasonic-electric field. The effect of multi-physical fields on the cracking tendency, microstructure, phase composition, mechanical properties and corrosive resistance of coating is investigated. As results indicate, the macro-morphology of coating is affected by the multi-physical field and the microstructure is refined, which uniformizes the element distribution and prominently optimizes the tribological and anti-corrosive performance of coating, the number of cracks in the coating under multi-physical field reduce by 76.92%, compared with that without physical field, the average microhardness increases by 37.89%, the average friction coefficient decreases by 61.96%, the average wear loss decreases by 61.05%, the corrosive rate decreases by 93.01%.
