Method for calculating thickness of oxide film of martensite heat-resistant steel under supercritical high-temperature steam

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 (μm), 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).
