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. WebA chromizing process conducted in a salt bath at temper-atures ranging from 500 to 550 °C via TRD with specimens subjected to a precursor plasma nitriding at 540–560 °C is referred to as low-temperature chromizing or simply as duplex chromizing. To the authors' knowledge, little has been reported
