High temperature common diffusion coatings

WebHigh-temperature corrosion is a chemical attack from gases, solid or molten salts, or molten metals, typically at temperatures above 400°C (750°F). High-temperature oxidation is one of high-temperature corrosion process involving the reaction between the metallic alloys or coating sand the atmospheric oxygen at elevated temperatures. WebBecause of the high temperature of the thermal diffusion process, the coating will not chip, peel or spall off the substrate, is extremely durable and will provide excellent protection from both ...
