Use of the method of electric arc spraying of coatings for the restoration of machine parts and structures

The possibilities of using protective electric arc coatings on machine parts and structures to improve their operational characteristics, reduce metal consumption, and renewal of worn parts are analyzed. The influence of parameters of electrode materials and different alloying systems on the characteristics of the obtained coatings is shown. The effectiveness of the composite coatings formed from two dissimilar wires – powder-coated and solid-drawn – are confirmed. Modern tendencies in the development of the electric arc method are studied.
