Basic principle of electrochemical metallizing
electrochemical metallizing is a method of electroplating that relies on a pad or brush in contact with the anode to provide electroplating. When electroplating, the pad or brush moves over the plated cathode. Brush plating uses a specially developed series of brush plating solutions, various forms of pen and anode, and a dedicated DC power supply. During operation, the workpiece is connected to the negative pole of the power supply, the plated pen is connected to the positive pole of the power supply, and the anode of the impregnated solution is wiped on the surface of the workpiece, and the metal ions in the solution are discharged and crystallized at various points where the surface of the part contacts the anode. And gradually thicken with time, due to the relative movement speed of the workpiece and the plated pen, it is an intermittent crystallization process for each point on the coating.
