Abstract

The elemental and phase composition of the surface layer of Hardox 450 steel with a composite TiB₂–Mo coating sprayed by an electro-explosive method are investigated after pulsed irradiation with an intense electron beam of submillisecond duration. Electron-beam treatment conditions leading to formation of a dense surface layer with high luster with a submicrograin structure on the basis of titanium diboride and nickel are ascertained. It is shown that an electron-beam treatment under melting rate leads to formation of a surface layer with homogeneous structure and uniform concentration distribution.
