Abstrakt: In this study Ti-Nb coatings formed on the surfaces of cp-titanium plates by electron beam cladding were investigated. It was found that the coatings were characterized by a dendrite structure and a quenched structure was observed in the interdendritic space. The energy dispersive X-ray analysis revealed some differences between the elemental composition of different areas corresponding to dendritic crystals and the space between them. The corrosion resistance of the Ti-Nb alloy obtained on the titanium surface in the concentrated nitric acid was almost 8 times higher than the cp-titanium corrosion resistance.
