Properties of 13% chromium wire electric arc spraying coatings

The article considers the nature and some mechanical properties of corrosionresistant metallizing steel coatings produced out of 13% chromium wires. The carbon is confirmed to influence on the phase composition, hardness, adhesion strength of the coating to the substrate, elasticity module and bending strength of the coating material. The authors estimated a relative wear resistance of sprayed coatings under abrasive friction. They showed the data on the adhesion strength and elasticity module of the coating depending on the carbon content in the 13% Chr wires. The difference in the adhesion strength of the coatings can be explained by quenching processes during spraying and the variability of the elastic module of the applied material.
