传统的电镀镀液无论如何复杂,都只能是单一的液相,而铁基复合电镀(以下简称复合镀铁)的镀液却有液相和固相两相同时存在,这种采用电化学的方法使固体微粒与金属离子共沉积,所获得的镀层被称为复合镀层。在复合镀层中,由于固体微粒均匀弥散分布在镀层中,因此,复合镀层综合了镀层中基质金属和固体微粒性能的特点,从而大大地改善了镀层的性能。日前已研制有Fe-Al_2O_3和Fe-SiC两种复合镀铁镀液。其配制方法是在处理好的单盐氯比亚铁电解液中,加入经过活化处理的Al_2O_3或SiC微
In any case, the conventional plating solution is only a single liquid phase. However, the plating solution of iron-based composite plating (hereinafter referred to as composite plating iron) exists in the same two phases of liquid phase and solid phase. Method of solid particles and metal ions co-deposition, the obtained coating is called the composite coating. In the composite coating, since the solid particles are evenly dispersed in the coating, the composite coating greatly improves the properties of the coating by combining the characteristics of the matrix metal and the solid particles in the coating. Has developed a Fe-Al_2O_3 and Fe-SiC two kinds of composite plating bath. The preparation method comprises the following steps of: adding activated Al 2 O 3 or SiC micro
