Blind hole M3 carbon steel blue and white zinc plated pressure weld stud.
Welding studs refers to the method of welding metal studs or other similar metal parts (bolts, nails, etc.) to the workpiece (usually plate) is called stud welding, and the stud used for welding here is called welding Studs.
The purpose of electrogalvanizing is to prevent steel objects from being corroded, improve the corrosion resistance and service life of steel, and at the same time increase the decorative appearance of the product. Steel will be weathered, water or soil corrosion over time. The steel that is corroded every year in China accounts for almost one-tenth of the total amount of steel. Therefore, in order to protect the service life of steel or its parts, electro-galvanizing is generally used to process steel.
Since zinc is not easy to change in dry air, and can produce a basic zinc carbonate film in a humid environment, this film can protect the internal parts from corrosion damage, even if the zinc layer is damaged by some factor. In some cases, zinc and steel combine over time to form a microbattery, with the steel matrix protected as a cathode.
Blue and white zinc plating - chemical or electrochemical methods are used to produce a colored film or interference film on the metal surface. The film is very thin, and sometimes the interference film itself has almost no color, and when the metal and the surface of the film reflect light At the same time, the light waves are canceling each other out to form various colors. When the thickness of the film gradually decreases, the color tone changes, generally from yellow, red, blue to green, until the color of the film itself is displayed. If the thickness of the film is not When uniform, it will produce iridescent or mottled variegation.
