Abstract

Objective On the basis of the experimental investigation of Fe-ZrO2nanocomposite coating, nanoZrO2particles were added to the bath to prepare the nanocomposite coating of Fe-ZrO2with electroplating methods and laser cladding. Methods Study the effects of nanocontent, cathodic pulse current density, duty cycle, the ultrasonic frequency content of the coating surface Nano, orthogonal optimization of process parameters. Results The results show that nanoparticles concentration 10 g/l, the cathode current density pulse 4A/dm2, the duty cycle 20%, ultrasonic frequency 180W, nanocomposite coating capacity of up to 5.5wt%. Conclusion Fe-ZrO2nanocomposite coating improved abrasion and Corrosion of the binary composite coating.
