Investigation of the steel parts’ hardsurfacing overlays properties

The article describes the studies’ results of steels with applied boron-based hardsurfacing overlays. overlay was done in four different ways. materials obtained differed chemical composition, properties and wear resistance. A detailed technical process surfacing charge which makes it possible to obtain necessary material, is given. Studies hardness, macro- microstructure, X-ray phase composition have been carried out. descriptions overlays’ characteristic phases are made their overlays has determined by emission spectroscopy method. analysis samples also out percentage additional modifier introduced into determined. Based on studies out, conclusions about optimal method metal hardening drawn.
