OBTAINING COMPLEX CHROME COATINGS USING COMPOSITE POWDER CHARGE

Abstract

In the work the methods of obtaining protective wear-resistant coatings on steels in the mode of thermal self-ignition are considered. The results of studies of the structure and properties of coatings obtained by different methods of processing (simultaneous and sequential) are shown. With the use of mathematical modeling methods, optimal charge compositions for applying wear-resistant coatings on machine parts using composite powder media have been developed. The analysis of significant parameters affecting the structure and operational properties of coatings obtained by different processing methods is given. The study of wear resistance of the obtained layers on carbon steels is carried out.
