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.

研究了基于自熔镍合金、铌和无定形硼的层的结构，这些层通过非真空电子束熔覆沉积，然后进行热处理（表面层熔化）。熔覆采用两种方法进行，即（1）在炉膛中加热至1000℃，淬火和低温回火和（2）通过高能电子束加热（束流从2到35mA不等） ）。结果表明，热处理产生了显着的结构变化和化学元素的重新分布。熔覆层的显微硬度在炉膛内熔合后在表面略有降低，在电子束处理后保持不变。
