Two surface treatment methods Blue and Black Processing Technology

Blue processing technology

Blue processing technology is a method of heating the surface of metal parts under specific conditions to generate a layer of blue oxide on their surface.

Suitable for fasteners made of various materials, especially carbon steel and stainless steel fasteners.

Advantages:
1. Color stability: The color is stable, not easily faded, and has a certain reflective effect.
2. Strong corrosion resistance: It has good corrosion resistance and can effectively extend the service life of fasteners.
3. Hardness improvement: After blueing treatment, the surface hardness of the fastener will be increased, which can improve its wear resistance and reduce the wear of the fastener. 、

Application areas:
In the automotive industry, fasteners treated with blue can improve the corrosion resistance of automotive components, extend their service life, and enhance the safety performance of cars
In the aerospace field, fasteners treated with bluing enhance their hardness and wear resistance, improving the safety and stability of aircraft.

Blackening processing technology

Blackening treatment technology is a method of chemically treating the surface of metal parts to form a black oxide film.

Mainly suitable for fasteners made of various metal materials, including carbon steel, stainless steel, copper, etc

Advantages:
1. Good corrosion resistance: Black oxide film can improve the corrosion resistance of fasteners and extend their service life.
2. High surface smoothness: The surface smoothness is high, with a reflective effect, increasing the aesthetic appeal of fasteners.
3. Not easy to stain: The surface of fasteners treated with blackening has a certain ability to absorb grease, making them less prone to dust and oil stains, reducing corrosion and contamination of fasteners

Blackening processing technology is mainly applied in the following fields:
1. Furniture manufacturing: Fasteners in furniture need to withstand long-term use and environmental influences. Blackening treatment can enhance the corrosion resistance of fasteners and increase the service life of furniture.
2. Construction engineering: Fasteners in construction engineering need to withstand significant pressure and various environmental conditions. Blackening treatment can increase the corrosion resistance of fasteners and ensure the safety of buildings.
