Due to the special properties of aluminum, special pretreatment is needed when the antirust aluminum plate is electroplated. However, the pretreatment needs to be adjusted due to different antirust aluminum plates and different parts conditions, so the general process can not be used simply. Therefore, for the workers engaged in electroplating on antirust aluminum plate, sometimes it is necessary to do the pre-treatment experiment of antirust aluminum plate

It is also a systematic comparison experiment to carry out the treatment scheme experiment of antirust aluminum plate before electroplating. Different pretreatment processes are selected for the sample, and then the same electroplating process is carried out. The key point of this comparison experiment is to ensure that except for the difference process points, other processes are under the same conditions, otherwise there is no comparability and evaluation can not be made
The pretreatment of aluminum wafer electroplating includes four important processes: degreasing, acid etching, electroless plating or displacement plating, and pre plating. Among them, electroless plating or displacement plating is the most important process. Therefore, the experiments often need to be done are concentrated on this process. Of course, different aluminum materials and different processing methods have different requirements for pretreatment, For example, the pre-treatment of die-casting aluminum parts and rolling aluminum parts is very different. Even if the same processing method is used, different aluminum materials also have different pretreatment processes. For example, the copper content of aluminum directly affects the adhesion of the coating
