Зносо- і корозійна тривкість електродугових покривів, напилених порошковими дротами серії Stein-Mesyfil

Abstract

The paper presents the influence of chemical composition and spray conditions of electric-arc coatings made of cored wires Stein-Mesyfil, in particular 953V, 932V, 954V, 957V on their abrasive-and corrosion-resistance characteristics. It is established that the least porosity and the greatest wear-abrasive resistance possess coatings under burning current of 350 A. Coatings made of of 932V and 957V are the most wear-resistant. No influence of chemical composition and spray conditions on the electrochemical properties of coatings in 3% sodium chloride solution was found.
