Fastener surface treatment is the process of forming a covering layer on the surface of the workpiece through a certain method, and its purpose is to endow the surface of the product with beautiful anti-corrosion effects.
Surface treatment is the process of forming a covering layer on the surface of the workpiece through a certain method. The purpose is to endow the product with a beautiful surface and anti-corrosion effect. The surface treatment methods are all attributed to the following methods:
1. Electroplating: Immerse the parts to be electroplated in the aqueous solution containing the metal compound to be deposited, and pass the current through the plating solution to precipitate the electroplated metal and deposit it on the parts. Generally, electroplating includes galvanized, copper, nickel, chromium, copper-nickel alloy, etc., and sometimes boiled black (blue), phosphating, etc. are also included.
2. Hot-dip galvanizing: It is completed by immersing carbon steel parts in a plating tank of molten zinc at a temperature of about 510 °C. The result is that the iron-zinc alloy on the surface of the steel gradually becomes passive zinc on the outer surface of the product. Hot-dip aluminum plating is a similar process.
3. Mechanical plating: Impact the surface of the product through the particles of the plated metal, and cold weld the coating to the surface of the product.
Generally, the screws are mostly electroplated, but hexagonal wood screws used in electric power, highways, and other outdoors are hot-dip galvanized; the cost of electroplating is generally 0.6-0.8 yuan per kilogram, and hot-dip galvanization is generally 1.5-2 yuan/kg, the cost is higher.
