Wear and corrosion resistance of electric-ARC coatings sprayed from powder wires of the Stein-Mesyfil series

Abstract

We investigate the influence of the chemical composition and modes of spraying of electric-arc coatings from powder wires of the Stein-Mesyfil series, in particular, 953V, 932V, 954V, and 957V, on their abrasive wear resistance and corrosion characteristics. It is established that all coatings obtained at a current of arc burning of 350 А, have the smallest porosity and largest resistance to abrasive wear resistance, and coatings obtained from 932V and 957V wires are most wear resistant. An influence of the chemical composition and spraying modes on the electrochemical properties of the coatings in a 3% solution of sodium chloride is not found.
