(Summary description)　Ceramic cylinder is a type of cylinder. It is usually used in the engine of motorcycles or yachts. The electroplating process is usually used. The principle of electrolysis is used to coat the conductor with a layer of metal to meet the needs. What are the functions? The specific content is as follows:
　　
　　Copper plating: used for primer to improve the adhesion and corrosion resistance of the electroplated layer. (Copper is easy to oxidize. After oxidation, the patina is no longer conductive, so copper-plated products must be protected by copper)
　　
　　2. Nickel plating: used as a primer or for appearance to improve corrosion resistance and wear resistance. (Among them, the wear resistance of chemical nickel exceeds that of chrome plating in modern technology). (Note that many electronic products, such as DIN head and N head, no longer use nickel as a primer, mainly because nickel is magnetic, which will affect the passive intermodulation in the electrical performance)
　　
　　 3. Gold plating: improve conductive contact impedance and enhance signal transmission. (Gold is the most stable and the most expensive.)
　　
　　4. Palladium nickel plating: Improve conductive contact resistance, enhance signal transmission, and have higher wear resistance than gold.
　　
　　5. Tin-lead plating: to improve soldering ability, and soon to be replaced by other substitutes (because of lead, most of them are now plated with bright tin and matte tin).
　　
　　 6. Silver plating: improve conductive contact impedance and enhance signal transmission. (Silver has the best performance, easy to oxidize, and also conducts electricity after oxidation)
