Structural features of deposited layers produced by the combined laser-microplasma method using powders of the Ni-Cr-B-Si system alloys were investigated. Technological advantages and drawbacks of a combination of laser cladding and microplasma spraying were determined. It was shown that the developed combined laser-microplasma method allows improving the quality of the deposited layers by preserving the key advantages characteristic of the laser powder cladding process.
