铁与硅粉及硅铁粉复合电镀工艺的研究

通过复合电镀铁与硅粉及铁与硅铁粉的方法在普通硅钢板表面增硅。研究了复合电镀工艺及粉末颗粒对复合层增硅量的影响。结果表明，随电流密度的增加，镀速加快，但复合镀层中的硅含量逐渐降低。同时，细化复合颗粒及增加镀液中的颗粒含量对提高复合镀层中的硅含量有显著效果。

Study on Composite Electroplating Technology of Iron with Powder of Silicon or Ferrosilicon

Increasing silicon content on the surface of common silicon steel sheet could be realized through the use of composite electroplating method of iron with silicon powder or with ferrosilicon powder. Effect of the composite electroplating technology and powder grain size on the amount of increasing silicon content at steel sheet surface was investigated. The results show that with the increase in current density the depositing speed of the composite coating is increased faster while the silicon content in the composite coatings is decreased gradually. The smaller grain size and higher concentration of powers in the plating bath have remarkable effect on the increase of silicon content in the composite coatings.
