The structure of layers based on self-fluxing nickel alloy, niobium, and amorphous boron deposited by non-vacuum electron beam cladding and then subjected to a heat treatment (with fusion of the surface layer) is investigated. The cladding is conducted by two methods, i.e., (1 ) heating in a furnace chamber to 1000°C, quenching and low tempering and (2 ) heating by a high-energy electron beam (the beam current is varied from 2 to 35 mA). It is shown that the heat treatment produces substantial structural changes and redistribution of the chemical elements. The microhardness of the clad layer decreases somewhat at the surface after the fusion in the furnace chamber and remains unchanged after the electron beam treatment.
