Abstract

Presents the results of comparative tests of corrosion resistance of ion-plasma layered coatings of the (Ti–TiN) + VSDP-13 system obtained after vacuum annealing and after saturation in metal plasma to protect the deformable intermetallic titanium ortho-alloy VIT6. Metallographic studies and studies of the phase composition were carried out after accelerated cyclic corrosion tests at a temperature of 700 °C on the basis of 10 cycles. An increase in the corrosion resistance of the alloy-coating composition was found when vacuum annealing was applied at a temperature of 700 °C for 5 hours relative to saturation in metal plasma.
