Abstract
- The technology of application of multicomponent diffusion coatings from the medium of low-melting liquid-metal solutions on hard alloys of the WC-6% Co type is described. The thickness of the coating varies depending on temperature and exposure time, and ranges from 5 to 10 microns. The results of elemental and metallographic analyzes are presented. It was found that during the formation of coatings, active diffusion of iron to the surface of hard alloys occurs with the formation of the FeNi intermetallic compound. The functional coating of the TiC-NiCu system on WC-6% Co hard alloys obtained by diffusion saturation in the medium of low-melting liquid metal melts is a solid solution of variable concentration with inclusions of TiC and WC. The phase composition on the surface of the hard alloy after diffusion saturation is: FeNi 44%, Cu 41%, TiC 12.5%, WC 2.3%, Co 0.2%. [ABSTRACT FROM AUTHOR]
