Several general indicators are used to evaluate any electroplating art, which are usually divided into indicators related to the performance of the plating solution and indicators related to the performance of the coating. Plating solution index is the main indicator of electroplating art, including the current effect of the plating solution, which is related to the deposition rate, dispersion ability, and exploration and plating ability. The crystallization state of the coating, the stability and operability of the plating solution include the control of process conditions, and there are special requirements for equipment), the degree of impact on the environment, and the economic benefits of electroplating processing costs.
The performance index of the coating is the index of the performance and quality of the coating guaranteed by the electroplating process. It is an important indicator for visually evaluating the level of electroplating, such as the decorative performance of the coating, the degree of brightness, the corrosion resistance, the brittleness of the coating, the porosity of the coating, etc. Functional coatings should be added with functional performance indicators. Such as conductance lift, reflected light coefficient. Weldability, wear resistance, etc.
These two types of indicators belong to high-level professional processes. Sometimes the process with good performance indicators of the plating solution does not necessarily have good coating indicators; and some processes with good coating indicators. The bath index is not good. People usually judge and select the electroplating process based on the coating index, that is to say, to obtain a good coating sometimes have to use a plating with poor performance of the plating solution, such as decorative chrome plating is a typical example. Many cyanide platings are also plating species with good coating performance but great impact on the environment.
