Electroplating quality standard
Corrosion is the destruction or deterioration of a material or its properties caused by the action of the environment. Most of the corrosion occurs in the atmospheric environment, the atmosphere contains oxygen, humidity, temperature changes and pollutants and other corrosion components and corrosion factors. Salt spray corrosion is one of the most common and destructive atmospheric corrosion.

Factors affecting the quality of electroplated coatings
The anode also has an effect on the quality of the coating during electroplating. Anodic oxidation generally undergoes three steps: activation zone (metal dissolution zone \passivation zone (surface generation passivation film) and over-passivation zone (surface generation of high-valent metal ions or oxygen evolution).

Matters needing attention in barrel plating process
Although the cathode current density of barrel plating is large, due to the difference of current density, most of the current consumption is on the workpiece with high current density, but the average current density is very small. As a result, the cathode current efficiency is low. If the operation is slightly negligent, the coating thickness is difficult to guarantee.

Master the four-point control hardware plating quality
Electroplating is a common way of surface treatment of fastener products such as hardware screws. Under normal circumstances, the quality of electroplating is mainly measured by its corrosion resistance, followed by appearance. Erosion resistance is to imitate the working environment of the product, set as the experimental premise, and perform erosion experiments on it. The quality of the plating of hardware screw products is controlled from the following 4 aspects:

The difference between hot galvanizing and electroplating
China is a big steel country, and its annual steel output ranks high in the world. Especially in the northern part of the heavy industry developed, steel plants, metallurgical plants abound, occupy most of the steel industry.
