Study on the Effect of the Sealers on the Steel Surface Layer Modified by Electrical Discharge Machining

Abstract:

The paper describes the influence of the composition of the sealer used to form a composite coating on the surface of a steel sample by electrical discharge machining along the sealing layer on the structure and properties of the coating. The object of this study is samples made of steel 45. All samples are treated by electrical discharge machining with the use of ПР-В3К (Stellite) hard alloy-based anode and modifying sealers, based on CrCNi, TiCNi, and non-stoichiometric W and Mo compounds. Besides, the paper presents the physical and mechanical properties of the obtained coatings, examined during a set of tribological tests. The conducted experiment demonstrated that the wear resistance of coated samples is higher, compared to coatless ones. The strong point of our study lies in functionality to employ sealers, based on the SHS-reagents and non-stoichiometric W and Mo compounds with ESA processing in friction units.
