本工艺提供了金属和固体无机颗粒在阴极零件上电共沉积方法。颗粒平均尺寸小于300μm,在镀液中的浓度为10～150克/升。无机颗粒悬浮在含氟碳表面活性剂的槽液中。表面活性剂含量至少使槽液中颗粒的重量比与表面活性剂对颗粒的重量比相同。颗粒在0.005NKNO_3溶液申的ζ电位至少为+40mv,适合的阳离子氟碳化合物表面活性剂组成应具有以下分子结构: 2[C_8F_(17)SO_2——(CH_2)_8—N (CH_3)_3]SO_4~(2-)
The process provides a method for electrically co-depositing metal and solid inorganic particles on a cathode component. The average size of the particles is less than 300 μm and the concentration in the bath is 10 to 150 g / l. The inorganic particles are suspended in the bath of fluorocarbon surfactant. The surfactant content is such that at least the weight ratio of the particles in the bath to the weight ratio of the surfactant to the particles is the same. The zeta potential of the particles in 0.005NKNO_3 solution is at least +40 mV. A suitable cationic fluorocarbon surfactant should have the following molecular structure: 2 [C_8F_ (17) SO_2 - (CH_2) _8-N (CH_3) _3] SO_4 ~ (2-)
