A motorcycle is usually composed of thousands of large and small parts, electroplating parts is an important part. Motorcycle electroplating parts according to the plating base material can be divided into metal electroplating parts and plastic electroplating parts, such as handlebars, fenders, rims, exhaust pipes, which belong to metal plating base parts; And the scooter shell, instrument, trademark, model logo is a plastic plated base. If the motorcycle plating is intact, the vehicle will look brilliant. On the contrary, if the plating has rust, scratches, dents, the vehicle is ugly, and further affect the rider riding image. Like some luxury large displacement imported motorcycles, such as trademarks, exhaust pipe rust, the car will be troublesome (because these parts are very difficult to buy).

（1）. Classification and characteristics of electroplating

The classification and characteristics of electroplating are mainly: electroplating can be divided into protective, decorative and functional three categories according to the use function.

1, protective coating: as the name suggests, this coating is used to prevent the corrosion of products and parts, in the motorcycle production process commonly used galvanized layer to protect the main parts of steel.

2, protection - decorative coating: This coating is the most widely used in the motorcycle production process, the processing process is more complex than the protective coating, at least two layers of plating, and some more. Such as motorcycle fender, rim, horn handlebars, exhaust pipe, etc.; In addition to good appearance, this coating can also play a role in preventing corrosion of the main parts.

3. Functional coating: This coating is usually applied to the friction surface of shaft parts, engine cylinders and piston rings. Generally, chromium plating is adopted to increase the wear resistance of the main parts.

4, other coating: the production of tires, in order to increase the adhesion between steel wire and rubber in hot pressing, the general method is to plate copper zinc alloy on the steel wire. Due to different uses, plating metal is also different, commonly used metals are zinc, copper, silver, lead, chromium, nickel, black chromium, black nickel and so on.

（1）. Protective measures for electroplating motorcycle parts

Electroplating Most corrosive solutions are stable in organic acids and can retain luster for a long time. However, the following situations may cause the electroplating to be corroded, and it is necessary to pay attention to and take measures to protect it.

1, should prevent contact with salt, hydrochloric acid, bittern and other substances. Because the coating is easily soluble in the above substances, so avoid contact with 84 disinfectant, bleaching powder, toilet cleaning and other substances.

2. Motorcycle should not be stored in a place with gas, briquette stove and soot. This is because carbon monoxide (CO) will cause the coating to produce gray-black mesh cracks and rust.

3. Pay attention to the method of wiping. Usually in a week only to motorcycle parts electroplating wipe a neutral oil, such as sewing machine oil. Pay attention to each time the oil should be wiped with a soft cloth to clean the dirt; After driving in rainy days, clean the dirt with clean water; Then wipe with a soft cloth, and finally dip in motor oil. When rubbing oil, do not touch the paint and tire, in order to prevent paint loss and tire aging. If there is water mist inside the meter and other coating, it should be dried with a hair dryer and then wiped.

4, for the galvanized surface on the strip, because the surface generated a dark gray basic zinc carbonate film, can effectively prevent the internal metal from corrosion, so when wiping the time does not have to pay attention to this layer of dark gray galvanized surface clean, polished, you can wipe some neutral oil to protect.

5, for plastic electroplating parts of the wipe, can only use a soft cloth dipped in water (warm water) wipe, can not dip in oil wipe, because it will destroy the plating of plastic electroplating parts.

6, for the exhaust pipe, fender, rim such plating parts, can not use wire brush dirt, because the wire brush brush will scratch the coating surface. Use clean water to loosen the dirt and dirt and then wipe it with the above method. If the bubble is not loose, the wood rod should be gently removed.
