Problems solved by technology

[0022] After the radiator is plated by the above electroless nickel-phosphorus alloy plating process, or after electroplating, the aluminum radiator or aluminum-copper composite radiator is plated with nickel-phosphorus alloy as a whole, including the welding surface and non-welding surface of the radiator. The non-welding surface of the radiator does not need to be plated, and the cost of the nickel-phosphorus alloy is relatively high, resulting in a high cost of the radiator

Embodiment Construction

[0042] In order to further disclose the present invention, the following in conjunction with the attached figure 2 And specific embodiment is described, and it comprises the following steps:

[0043] The 1st step, carry out pretreatment to radiator, it is to carry out degreasing, water washing, weak corrosion (using lye to carry out weak corrosion to it), water washing, light emitting (pickling), water washing to radiator successively; Pretreatment of the present invention The process of each step in the process is the same as the current pre-treatment process commonly used;

[0044] The 2nd step, chemical oxidation, put radiator into the hot water that contains oxidizing agent, described oxidizing agent is organic amines, and oxidizing agent is triethanolamine or hexamethylenetetramine (urotropine) etc.; Radiator after oxidation The surface of the radiator is covered with a layer of colorless porous oxide film; wherein, the temperature of the hot water is 80-95°C, and the o...

Abstract

The invention relates to an electroplating and chemical plating process technique field of aluminum and aluminum copper composite radiator, in particular to a chemical etching partial electroplating and chemical plating process of aluminum and aluminum copper composite radiator. The invention proceeds with the chemical oxidation, enclosing and partial electroplating and chemical etching before thedip-zinc process of the radiator is proceeded. That is, the connection portion of the aluminum and aluminum copper composite radiator and host machine is electroplated the nickel phosphide alloy withweldability. The invention is called the partial electroplation because the portion of aluminum or aluminum copper composite radiator is electroplated. The technique is used for the partial electroplation of aluminum or aluminum copper composite radiator, which is provided with the simple technology, saves the nickel resource, and reduces the production cost.

Description

Technical field: [0001] The invention relates to the technical field of electroplating and chemical plating processes for aluminum or aluminum-copper composite radiators, in particular to a partial electroplating and chemical plating process for chemical etching of aluminum or aluminum-copper composite radiators. Background technique: [0002] The aluminum radiator is a radiator formed by stacking many aluminum sheets through machining, while the aluminum-copper composite radiator is a radiator formed by tightly interspersing copper heat pipes in the aluminum radiator. Due to the poor weldability of aluminum, in order to connect the above-mentioned aluminum radiator or aluminum-copper composite radiator to the host that needs heat dissipation, it is necessary to coat the part where the aluminum radiator or aluminum-copper composite radiator is connected to the host. Weldable nickel-phosphorus alloy to weld the two together. [0003] The surface of aluminum is easy to form a...
