STUDY OF THE STRUCTURE AND PROPERTIES OF THE COATINGS OBTAINED BY THE METHOD OF ELECTRON BEAM SURFACING OF POWDER MIXTURES (NB + C, TI + NB + C)

В работе были исследованы поверхностно-упрочненные слои, полученные методом вневакуумной электронно-лучевой наплавки смесей порошков Nb + C, Ti + Nb + C на основу из титанового сплава ВТ5-1. Результаты исследования показали, что максимальной микротвердостью обладают покрытия, полученные при наплавке смеси порошков Nb + C.Surface hardened layers formed by non-vacuum electron beam cladding of powders Nb + C, Ti + Nb + C on the basis of titanium alloy VT5-1 were studied. Results showed that coatings obtained during surfacing mixture Nb + C powders have the maximal microhardness value
