An overview of the oxidation performance of silicide diffusion coatings for vanadium-based alloys for generation IV reactors
Source abstract
Abstract
Abstract This study focuses on the development of new protective coatings for the vanadium-based alloy V-4Cr-4Ti. Halide-activated pack-cementation (HAPC) technique was used to develop V x Si y multilayered diffusive silicide coatings. The outer layers (coatings) were formed of VSi 2 doped with 27 at.% Cr or TiSi 2 . These compounds exhibited a very low oxidation rate at 650 °C, both in air and at a low oxygen pressure (He, 5 ppm O 2 ). The coatings formed mainly of MSi 2 were found to be insensitive to pesting and largely unreactive to liquid sodium ( 2 ) during a 360 h compatibility test at 550 °C.
