In article the cathodic cleaning processes of aluminum alloyAW 5754 and cleaned substrate surface coating by plasmawith Ni-Cr-Fe-Si powder were researched. Aluminium substrateroughness after cathodic treatment at different cathodic treatmentparameters was established during the experiments. During theinvestigation a comparison of the calculated medium power1.6 to 9 kW plasma torch voltage-current characteristics withthe experimental results was made. The optimized parametersof aluminium cathode substrate cleaning process were selected;porosity and morphology of plasma sprayed nickel-based coatingwere determined.
