  • METHOD FOR CALCULATING THICKNESS OF OXIDE FILM OF MARTENSITE HEAT-RESISTANT STEEL UNDER SUPERCRITICAL HIGH-TEMPERATURE STEAM
    Publication number: 20210202050
    Abstract: A method for calculating a thickness of an oxide film of a martensite heat-resistant steel under supercritical high-temperature steam is disclosed, which includes following steps: the martensite heat-resistant steel is a 9% Cr martensite heat-resistant steel; and a formula for calculating the thickness of the oxide film is X = A ? ? exp ? ( - Q R ? T ) ? t n , which X is the thickness of the oxide film (?m), A is a constant coefficient, Q is an activation energy (J·mol?1), R is a gas constant, T is temperature (° C.), and t is time (h).
