Early oxidation behavior of Si-coated titanium
Source abstract
Abstract
Abstract Oxidation of pure Ti coated with a thin Si layer was investigated to clarify the role of titanium silicide phases in improving oxidation resistance of titanium alloys. The system initially reacted to form a two-layer structure with Ti5Si3 and SiO2. Oxidation proceeded by upward diffusion of Ti to form TiO2 wedge-like crystals on the surface and inward oxidation of Ti5Si3 into a mixed nanocrystalline TiO2 and SiO2 internal scale that was locally layered. The Ti5Si3 phase inhibited oxygen inward diffusion, thereby limiting oxygen ingress into Ti and retarding inward Ti oxidation until the silicide layer was completely oxidized.
