High temperature oxidation in boiler environment of chromized steel

The demand for increasing efficiency has led to the development and construction of higher operating temperature power plant. This condition may lead to more severe thickness losses in boiler tubes due to excessive corrosion process. Hence, the research to improve the corrosion resistance of the cur...

In this research, the effect of chromizing process on the oxidation behaviour of T91 steel was investigated under steam condition.
