Abstract
Results of experimental and numerical investigations of the process of creating coatings from the titanium-aluminum intermetallic compound by using an additive method are presented. It is demonstrated that the process of intermetallic compound formation is limited by the rate of titanium dissolution and diffusion in the aluminum melt. The proposed method can be applied for hardening titanium plate surfaces during their exploitation at high temperatures and pressures.
