Development of a flux-cored wire for surfacing mining equipment operating in the conditions of shock-abrasive wear

Abstract

The effect of introducing various elements into the charge of a powder surfacing wire was studied. The dependences of the deposited layer hardness and its wear resistance on the mass fraction of the elements that make up the powder wires were determined by the method of multifactor correlation analysis. A new composition of the flux-cored wire used for surfacing mining equipment operating in the conditions of abrasive wear was developed.
