| Abstract: | Al Zn hot dipped cladding was prepared on carbon steel (Q235) sheet by passivation method. The growth kinetics of the intermetallic layer formed in 55?% Al Zn hot dipping bath was analyzed. A model of the growth kinetics and its calculation method were presented. Based on the experimental results, the growth relations of the intermetallic layer at different temperature and the activation energies of diffusion were obtained by curve fitting method, and the effect of silicon on the forming of intermetallic layer in the bath was also discussed. |
