Influence of Cold-Sprayed Al/Ti Deposition on High-temperature Oxidation and Mechanical Properties Deterioration of Ti-Al-Nb Intermetallic Substrates
Original language description
In the study, four powder blends of Al (oval, 14?77 um) doped with various Ti (angular, 11?50 um) content were prepared as feedstock material for cold spray deposition: Al, Al5Ti, Al15Ti, Al30Ti. Protective layers of the blends designated for deliberateoxidation were then deposited onto Ti-46Al-8Nb intermetallic substrates at 300'C, while preserving their initial chemical composition and retaining their original Al:Ti ratio. No oxidation of the materials during deposition was detected. A two-stage heat-treatment in an inert argon atmosphere (480'C/2hrs + 520'C/3hrs) was then carried out in order to induce desirable diffusion-driven processes to aid the anti-oxidizing performance indicators for the subsequent high temperature testing. Following the treatment, the specimens were subjected to 950'C air exposure for 100, 250 and 500hrs, respectively. It was found that the oxidation of the specimens was substantially reduced for the low-Ti content coatings (an increase in oxide content of
