Anti-weld coating for the production of hollow parts by diffusion welding and superplastic forming

Abstract

The work is devoted to the development of an effective and import-independent composition of an anti-welding coating for further use in serial technological production in the manufacture of hollow parts from titanium alloy VT6 by diffusion welding and superplastic forming. It is shown that the obtained composition of the anti-diffusion coating is inert to the titanium alloy at the temperatures of the diffusion welding process. The protective coating can be used for diffusion welding of titanium blades of a gas turbine engine, ensuring the connection of only certain areas to impart the necessary strength and rigidity, while maintaining a light hollow structure.
