The regularities of structure formation of multilayered functional gradient composites are studied. The composites are fabricated by means of the authors' new technology which is based on ion plasma sputtering of a plate-like target combined of W, Ta, Hf, Ti, Cr, Zr, C in highly pure inert ambient. The elemental distribution in width, phase composition and structural and morphological characteristics of the coatings were studied using X-ray diffraction, EDX and electron microscopy methods. The total functional capabilities of the layers in the produced multicomponent gradient composite and the presence of carbides of a metal mixture in its content indicate the prospects of its possible application as a structural material for nuclear power engineering.
