The advantages and disadvantages of Electroplating?
The advantages and disadvantages of Electroplating?
The electroplating is to use the product dipped into the electrolyte, conduct electricity, and form a thin layer of electroplating on the surface of the product by electrolysis (generally 5~10μm).
Advantages:
1. The surface flatness of the coating is extremely high, which can form a mirror surface
2. Different coatings can be used to change the performance of the product, such as enhancing the conductivity and the hardness.
3. Strong adhesion, it is almost impossible to fall off in daily use.
4. High level
Disadvantages:
1. It is almost none have the concealer ability, which has extremely high requirement on the surface of the workblank .
2. High quality materials, such as zinc alloy, steel, plastic, etc. (aluminum and aluminum alloy plating performance is poor).
3. The abrasion resistance is poor, the general metal coating abrasion resistance is poor, but there also have the exceptions (titanium plating , chrome plating and other metals can obviously enhance abrasion resistance).
4. The corrosion resistance is generally poor, the general electroplating layer can be tested for 24~48 hours by salt spray, and the powder can be tested by salt spray over 1000 hours.
5. Pollution, not environmental protection. So there are few local electroplating factories in foshan.
6. High cost
