Several general indicators are used to evaluate any electroplating process, which are usually divided into indicators related to the performance of and indicators related to the performance of the coating. The plating solution index is the main , including the current efficiency of the plating solution (related to the deposition rate), the dispersion ability, the deep plating ability, the crystallization state of the plating layer, the stability and operability of the plating solution (including the control of process conditions, Whether there are special requirements for equipment), the degree of impact on the environment, economic benefits ( electroplating processing costs), etc.
The coating performance index is the index of the coating performance and quality guaranteed by the electroplating process. It is an important indicator for visually evaluating the level of the electroplating process, such as the decorative performance, brightness , corrosion resistance, coating brittleness, and coating porosity of the coating. Functional coatings should be added with functional performance indicators, such as electrical conductivity, reflected light coefficient, weldability, wear resistance, etc.
These two types of indicators belong to high-level professional processes. Sometimes the process with good does not necessarily have good coating indicators; while some processes with good coating indicators have poor plating solution indicators. People usually judge and choose the electroplating process based on the coating index, which means that in order to obtain a good coating, sometimes it is necessary to use a plating type with poor performance of the plating solution. For example decorative plating is a typical example. Many oxide platings are also plating types that have good coating performance but have a great impact on the environment.
