Using the Cr–C–B systems for alloying metal by in out-of-vacuum electron beam surfacing

Abstract

Electron beam surfacing in an electron accelerator using powder mixtures of chromium carbides with boron carbide in different weight ratios and with different radiation parameters was used to produce wear- and corrosion-resisting coatings. It is shown that there are compositions of the surfacing mixtures and conditions of electron beam effect ensuring maximum values of wear and corrosion resistance.
