Metal coating protection, metal coating on the surface of the equipment are the most common with electroplating, spray coating, brush plating and so on. Electroplating not only makes the surface of the equipment beautiful, but also can make the equipment rust, corrosion, it is widely used in the production practice. However, a large area of plating, by plating equipment restrictions, the general factory does not attach such a workshop, therefore, this method is not introduced here. Mainly on the metal surface of the metal spray protection. Metal spray step is to use compressed air to melt the metal atomized particles, sprayed on the surface of the workpiece to form a metal coating. Metal surface Before spraying, it is necessary to pre-rust the surface and make the surface rough. Spraying process and equipment are relatively simple, and basically without the equipment, parts of the size and shape of the restrictions, according to the need to get a good metal or alloy coa...
A coating is a covering applied to the surface of an object, often referred to as a substrate. The purpose of applying the coating may be decorative, functional, or both. The coating itself may be a full coating, completely covering the substrate, or it may cover only the portion of the substrate. An example of all of these types of coatings is the product label on many beverage bottles - one side with a full-function coating (adhesive) and the other with one or more appropriate patterns (printed) to form words and images. Paint and paint are mainly used to protect the substrate and decorative dual-use paint, although some artists paint only for decoration, and large industrial pipe paint may only be used to prevent corrosion. Functional Metal Coating can be used to alter the surface properties of the substrate, such as adhesion, wetting, corrosion resistance or abrasion resistance. In other cases, such as the manufacture of semiconductor devices in which the substrate is a w...
