The distribution of silicon at cross section of cathode (/mm) 20 X 20 X 0. 5 sheet of 1. 6Si non-oriented cold rolled silicon steel after electro-deposit treatment by NaCl-KCl-NaF-SiO

molten salt with current intensity 50 mA/ cm

electro-deposit pulse current positive-negative ratio 9:1 at 750 ~ 850 ℃ for 60min has been tested and the diffusion coefficient of Si is obtained by calculation. Results show that with increasing electro-deposit temperature from 750 ℃ to 850 ℃
the Si content in sample increases and the diffusion depth increases from 18 μm to 40 μm ; the relation between electrodeposit temperature and diffusion coefficient of Si in steel is similar to Arrhenius exponential relationship.
