“…This fact indirectly indicates an increase of tantalum in dendrite branches, which are not subjected to intensive etching. The presence of segregation was also observed in [16] where electron beam cladding of tantalum and zirconium powders was described.…”

In this paper structural investigations and mechanical tests of Ti-Ta-Zr coatings obtained on surfaces of cptitanium workpieces were carried out. It was found that the coatings had a dendrite structure; investigations at high-power magnifications revealed a platelet structure. An increase of tantalum concentration led to refinement of structural components. The microhardness level of all coatings, excepting a specimen with the maximum tantalum content, was 370 HV. The microhardness of this coating reached 400 HV. The ultimate tensile strength of cladded layers varied from 697 to 947 MPa. Adhesion tests showed that bimetallic composites were characterized by high bond strength of cladded layers to the substrate, which exceeded cp-titanium strength characteristics.

“…This method allows obtaining one-and two-layer coatings with a thickness of up to 2 and 4 mm, respectively [15][16][17][18][19][20][21]. Nonvacuum electron beam cladding is realized using ELV-6 industrial accelerators developed in the Budker Nuclear Physics Institute SB RAS.…”
