Ultrasound-Pulse Electrodeposition Preparation of Fe-Nano ZrO2 Functional Gradient Coating

Objective On the basis of the experimental investigation of Fe-ZrO2 nanocomposite coating, nanoZrO2 particles were added to the bath to prepare the nanocomposite coating of Fe-ZrO2 with 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-ZrO2 nanocomposite coating improved abrasion and Corrosion of the binary composite coating.
