Fire-polished coating-steel interface structure

An important aspect of producing coatings with gradientlayer structure is the interface between the sputtered layer and the base metal. Fire polishing of selffluxing alloys is a necessary stage of treatment of sputtered layers, which ensures high adhesion of the coating to the base material. In this context, it is perti� nent to study specific features of the interaction between the coating and base materials and to deter� mine the optimal parameters of heat treatment with the consideration of the effect of the transition zone on the physicomechanical and performance proper� ties of sputtered layers.
