Beschreibung
Zusammenfassung:	manufacture of titanium alloy structure; sheet stamping and die forging; heat treatment of titanium alloys. SUBSTANCE: proposed method includes cleaning blanks, machining degreasing in acetone or in cleaning fluids dehydration in commercial alcohol, heating blanks in heat-treating furnace at temperature of 250 to 280 C for 1.5 to 2.0 hours for forming dense oxide film on surface followed by applying the protective coat and drying it. EFFECT: improved technological and protective properties of coats; reduced content of gas admixtures in surface layer of finished articles. 2 tbl
