Electromagnetic Strip Mills' Driving Rollers Metallisation Advanced Technics

Abstract

The continuous increase of the applications of thermal sprayed coatings together with the demand for layers having always more and more enhanced performances and properties stimulates the research activity toward the development of new coating materials and alloys. To meet this goal, new complex alloys, based on the Fe, Si, B, Mo, Cu, W system, are here considered, through the development of new and innovative powders to be used, as powders directly or as a wire form, for thermal sprayed coatings to improve wear and corrosion resistance, as well as thermal fatigue properties of the electromagnetic strip mills' driving rollers, highlighting the materials performances and attaining economical and environmental advantages.
