but also prevents the main parts from rusting. 3. Functional coating: This coating is usually applied to the friction surface of shaft parts, engine cylinders and piston rings. Chrome plating is generally used to increase the wear resistance of the main parts. 4. Other coatings: In the production of tires, in order to increase the adhesion between the steel wire and the rubber during hot pressing, the general method is to plate a copper-zinc alloy on the steel wire.
Due to different uses, the metal plated is also different. Commonly used metals include zinc, copper, silver, lead, chromium, nickel, black chromium, and black nickel. 2. Protective measures for electroplated parts Most of the electroplated layers are corrosive solutions, which are stable in organic acids and can maintain gloss for a long time. However, the following conditions will cause corrosion of the electroplated layer, which requires attention and measures to be taken to protect it. 1. Avoid contact with salt, hydrochloric acid, bittern and other substances.
Because the coating is easily soluble in the above substances, it is necessary to avoid contact with 84 disinfectant, bleaching powder, toilet cleaner and other substances. 2. Do not store the motorcycle in a place where there is gas, briquettes, or coal smoke. This is because carbon monoxide (CO) will cause the coating to produce gray-black mesh cracks and rust. 3.
Pay attention to the Electric Bikes Manufacturers of wiping. Usually, you only need to rub a neutral machine oil, such as sewing machine oil, on the motorcycle electroplating layer once a week. Note that every time you wipe the oil, you should wipe off the dirt with a soft cloth; after driving in rain, wipe off the dirt with clean water; then wipe with a soft cloth, and finally wipe with engine oil. Do not touch the paint and tires when rubbing the oil to prevent the paint from losing gloss and tire aging. If there is water mist inside the instrument and other coatings, it should be dried with a hair dryer before wiping. 4.
