Enhancing high-temperature oxidation resistance of tantalum-tungsten alloy with composite coating
Source abstract
Abstract
The poor oxidation resistance of tantalum-tungsten alloy at high temperatures limits its development as an ideal candidate for thermal components in aerospace. In this study, a composite coating including an internal TaSi 2-WSi 2 layer and an external ZrB 2-MoSi 2-ZrSi 2 layer was prepared on the surface of Ta10W alloy by combining slurry sintering and halide activated pack cementation (HAPC). The composite coating has a dense structure, and the coating samples remains intact after oxidation at 1500°C for 6 hours, while the unprotected substrate oxidizes to powder within 3 minutes. The coated samples also withstood more than 300 shock heating cycles from room temperature to 1500°C. Its notable resistance to high-temperature oxidation was ascribed to the development of a compact and uniform SiO 2 oxide layer containing oxide crystals comprising ZrSiO 4, ZrO 2, and Ta 2O 5 during the oxidation process, which effectively mitigated the diffusion of oxygen into the interior of the coating.
