FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, particularly, to production of articles by layer-by-layer additive build-up. It can be used for production of parts of turbomachines. Separate elements of turbo machine part are made by method of layer-by-layer additive growth, having shell enveloping empty volume corresponding to solid part of part. Separate elements of turbo machine part are assembled with formation of semi-finished part with internal empty space. Cavity of the semi-finished part is filled with volumetric fluid material, volumetric fluid material is compacted and cured in the cavity.
EFFECT: possibility of making parts from different materials, which enable to achieve optimum combination of properties of end product, for example, chemical and/or mechanical resistance, as well as protection of surfaces from corrosion in oil and gas environment.
