防锈铝板进行电镀时,因为受到铝的特殊性能的影响,需要有特殊的前处理,而这些前处理因不同防锈铝板和不同制件状况而需要有所调整,不能简单沿用通用工艺.因而,对于从事防锈铝板上电镀的工作者,有时需要做防锈铝板电镀前处理的实验.
Due to the influence of the special properties of aluminum, special pretreatment is needed for the electroplating of antirust aluminum plate. These pretreatment needs to be adjusted for different antirust aluminum plate and different parts, so the general process can not be simply used. Therefore, for the workers engaged in the electroplating of antirust aluminum plate, it is sometimes necessary to do the experiment of pretreatment of antirust aluminum plate
进行防锈铝板电镀前的处理方案的实验,也是系统化的比照实验,需要对样件进行不同选定前处理工艺的处理,然后进行相同的电镀加工,再检测其结合力.这种比照实验的要点是要保证除了差别工艺点外,其他流程都是同一条件的,否则就没有了可比性而无法做出评价.
The experiment of pre-treatment scheme for antirust aluminum plate electroplating is also a systematic comparative experiment. The sample needs to be treated with different pre-treatment processes, and then the same electroplating process is carried out, and then its adhesion is tested. The key point of this comparative experiment is to ensure that other processes are under the same conditions except for different process points, otherwise there will be no comparability and no evaluation


前处理工艺的选型和改进的办法的设计.铝圆片电镀前处理包括除油、酸蚀、化学镀或置换镀、预镀等四个重要工序.其中较为关键是化学镀或置换镀,因而,常常要做的实验都集中在这道工序上.
The pre-treatment 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 one. Therefore, the experiments are often focused on this process
当然不同的铝材和不同的加工办法对前处理有不同的要求,比方压铸铝件与轧制铝件的前处理就有很大区别,而即使是同一种加工方法,不同的铝材也有不同的前处理工艺,比方铝的含铜量的多少就直接影响其镀层的结合力.
Of course, different aluminum materials and different processing methods have different requirements for pretreatment. For example, the pretreatment of die casting aluminum parts and rolled aluminum parts is very different. Even if it is the same processing method, different aluminum materials also have different pretreatment processes. For example, the copper content of aluminum directly affects the adhesion of the coating
