【Abstract】 The reactions that may occur during aluminization were determined through the thermo-dynamical analysis. According to the principles of thermo-dynamics and diffusion, the aluminum transport from the powder to the surface of the steel was studied and a method that evaluates the kinetic parameter of HK40 steel was developed. The result shows that the method of predicting the kinetics of pack aluminization of HK40 steel was in agreement with experimental data.更多还原
