Heat Resistance of Vacuum Arc Deposited TiAl Coatings on VTI-4 Alloy

The paper studies intermetallic coatings based on the Ti–Al system obtained by plasma-assisted vacuum-arc deposition. The coatings are deposited by three different techniques to gain the different elemental and phase compositions. The study of the oxidation kinetics shows that the coating with the g...

Description
Summary:The paper studies intermetallic coatings based on the Ti–Al system obtained by plasma-assisted vacuum-arc deposition. The coatings are deposited by three different techniques to gain the different elemental and phase compositions. The study of the oxidation kinetics shows that the coating with the gradient aluminum distribution possesses the best oxidation resistance. It is found that after 500 hours of oxidation, its structure and weight remain unchanged.
