试验了通过NaCl-KCl-NaF-SiO₂熔盐在电流密度50 mA/cm²、电沉积脉冲电流正反向比9:1和750⁸50℃60min电沉积下阴极（/mm）20×20×0.5的1.6Si无取向冷轧硅钢片断面层硅的分布,并通过计算得出Si的扩散系数。结果表明,电沉积温度由750℃提高至850℃时,试样中Si含量增加,扩散的深度由18μm提高到40μm;电沉积温度与Si在钢中的扩散系数近似符合Arrhenius指数关系。 The distribution of silicon at cross section of cathode（/mm） 20 × 20 × 0.5 sheet of 1.6Si non-oriented cold rolled silicon steel after electro-deposit treatment by NaCl-KCl-NaF-SiO₂ molten salt with current intensity 50 mA/cm²,electro-deposit pulse current positive-negative ratio 9:1 at 750 850 ℃ for 60 min has been tested and the diffusion coefficient of Si is obtained by calculation.Results show that with increasing electro-deposit temperature from 750 ℃ to 85... 

通过制备磷酸二氢铝硅钢涂层,研究了氧化锌对无铬涂层耐盐雾性能、电化学性能和附着性的影响。结果表明,硅钢表面涂层含有4.0%的氧化锌时,涂层具有最高的耐腐蚀性能和电化学性能,而且其致密表面最为平整,没有裂纹出现。 The effects of ZnO on the salt spray resistance property, electrochemical performance and adhesiveness of silicon steel insulating coating were studied. The results show that the best corrosion resistance and electrochemical properties can be obtained when the coating contains 4.0% oxide zinc, and the dense surface is smooth without cracks.
