Abstract
AbstractThe paper shows studies boride coatings, which were created using treatment with currents. Chemical reactions characterized the boriding procedure at various temperatures are presented. To establish practically realizable reactions of surface chemical (topochemical) boriding and the accompanying high-temperature processes, a model mixture was prepared containing P-0.66 flux and boron carbide. A method of the experimental study of coatings applied on specimens by HFC-heating was developed. A study of the composition and properties of the products formed during the SHS process in the basic mixture on the surface of S355 steel parts during HFC-heating has been made, and it has been shown that aluminum oxide, aluminum nitride (by-product), and amorphous boron are formed under these conditions, and composite porous inhomogeneous coatings up to 250 μm thick, based on aluminum oxide, SHS products in the basic mixture and traces of high-speed HFC-boriding products are formed on the workpiece surface. The formed coatings are composite materials based on alumina, SHS products in the base mixture and the product of fast HFC-boriding of the surface of a steel part being formed during SHS-boriding, having the porous heterogeneous structure, insufficient thickness and low hardness.KeywordsSHS processesHFC-heatingHardening coatingsCoating powders
