Abstract
A method of inhibiting hot sulfidation corrosion of a metal surface and modifying the characteristics of any deposit thereon comprises the step of applying to such metal surface and any deposit thereon an inhibitor-modifier. The inhibitor-modifier is a mixture of chromium oxide and manganese oxide, the combustion product of a solution containing a soluble chromium compound and a soluble manganese compound, or a combination of the mixture and combustion product. The mixture and the solution contain chromium and manganese in a molar ratio of at least 1:1.
