Equipment and method for metal electrolytic coating of electroplated conductive material objects on electric heating tubes

Equipment and method for metal electrolytic coating of conductive material objects, wherein the object has at least two surface parts that are expected to be coated with layers of different thicknesses. The device includes an anode. Design equipment to receive objects in such a way that they form a cathode and, upon receiving the object, form a space for receiving liquid absorbing materials and electrolytes for coating the object. The main body of the anode includes at least two surface parts with different conductivity, which are arranged opposite to the surface part of the received object.

The electroplating method of aluminum alloy relates to an electroplating method characterized by a process method. Provide a simple, efficient, low pollution, low cost, wide operating range, and stable coating performance electroplating method for aluminum alloy. Chemical degreasing, water washing, and air drying of aluminum alloy substrate; Oxidize, wash, and blow dry the aluminum alloy substrate after chemical degreasing, washing, and blowing; Activate, wash, and blow dry the aluminum alloy substrate after oxidation, washing, and blowing; Remove the film from the activated, washed, and dried aluminum alloy substrate and wash it with water; Neutralize and wash the aluminum alloy substrate after membrane removal and water washing for the first time; Neutralize and wash the aluminum alloy substrate for the first time by depositing zinc, washing, and removing zinc; After the first zinc precipitation, water washing, and zinc removal, the aluminum alloy substrate is subjected to a second zinc precipitation, water washing, and zinc removal; Neutralize and wash the aluminum alloy substrate after the second zinc precipitation, water washing, and zinc removal process; The target product is obtained by plating the aluminum alloy substrate after the second neutralization and washing with watt nickel.
