Abstract

In a principally new way the ceramic-metal composition material based on the components SiC-Al2O3 which contains the metallic constituent of the iron, not introduced in to the initial batch mixture in form of powder, and that is acquired in re-sult of batch mixture components grinding in the steel vessels with steel milling bodies has been acquired. The acquisitions possibility of gas-flame coatings made of this ceramic-metal substance on the steel items for their superficial repair and rein-forcement has been investigated. Optimal modes of these coatings depositions of this material by detonation method have been found. Using the method of electron microscopy and focused-beam microscopy, X-ray spectrometry analysis and X-ray phase analysis the structure of the coatings made of the composition material containing the wearproof component SiC-Al2O3 and metallic bound of iron acquired in a result of batch mixture grinding in the steel vessels on the mild carbon steel has been studied. The tribotechnical properties of the coatings within the friction conditions without lubricants in air together with steel counterbody have been researched and application limits of the acquired coatings have been found. Using the methods of electron microscopy the friction surfaces of the acquired coating have been researched and features and regularities of their wear mechanism have been detected.
