There is investigated the wear resistance of mottled irons with stabilized carbide phase, obtained by alloying iron with copper, chromium and sulfur. It is shown that during heat treatment the outer shell of the carbide phase inclusions, destabilized with copper, dissolves, leaving a core stabilized with chromium. Carbon from the carbide phase dissolution coats the surface of manganese sulphide inclusions, forming additional wear-resistant structural component of mottled iron. The resulting structures can be attributed to compositional structures, which morphology and phase composition can be controlled by alloying and heat treatment.

The structural and phase transformations in tungsten-containing functional coatings of carbon steels manufactured during high-energy processes of implanting micro-powders of tungsten carbide through the method of complex pulse electro-machining are investigated. It is shown that in the course of a thermo-force impact in the area of deformation passes an intensive steel austenitizing with tungsten carbide powder dissolution with the further formation of composite gradient structures as a result of the decomposition of super-cooled austenite oversaturated by tungsten both through a diffusion mechanism, and a mechanism of spinodal stratification.
