Investigation of plasma-powder hardfacing of Hadfield steel with impact treatment

Abstract

The combination of forging with plasma-powder hardfacing is a further development of the method applied in the reconditioning of railway junctions. The process, equipment and the effect of impact energy on the properties of layers are investigated. The technology is promising for the hardening (reconditioning) of long components and eliminates the need for preliminary bending and subsequent heat treatment.
