Description

What is the blue surface treatment of the metal surface? What is the blue treatment on the metal surface? The blue treatment on the metal surface is a process of metal heat treatment. The blue color is to heat the steel in the air or directly immerse it in the concentrated oxidizing solution, so that A material protection technique that produces a very thin oxide film on the surface, also known as blackening.

The blue color of steel parts can be carried out in molten salt of sodium nitrite and sodium nitrate, or in hot air at high temperature and superheated steam above 500 °C, more commonly in concentrated caustic soda with sodium nitrite. heating. The composition of the solution when blue is emitted, the reaction temperature and time of the Aluminum Wheel Polishing Machine depend on the composition of the steel substrate. The blue film is made of magnetic iron oxide and has a thickness of 0.5 to 1.5 microns. The color is related to the material composition and process conditions, such as grayish black, dark black, and bright blue.

The separate blue film has poor corrosion resistance, but after oil coating or varnishing, the Aluminum Wheel Polishing Machine has improved corrosion resistance and friction resistance. When blue is emitted, the size and finish of the workpiece have little effect on the quality. Therefore, it is often used in precision instruments, optical instruments, tools, hardness blocks, etc. Can be replaced by electroplating, etc., often used for metal rust and corrosion protection.
