Six Treatment Processes for Stainless Steel Surface

发布时间：2024-03-19

1. Mirror treatment
The mirror treatment of stainless steel, in simple terms, refers to the polishing of the surface of stainless steel. The polishing methods are divided into physical polishing and chemical polishing. Local polishing can also be performed on the surface of stainless steel, with polishing levels divided into ordinary polishing, ordinary 6K, fine grinding 8K, and ultra strong fine grinding 10K. The mirror gives people a feeling of simplicity and a fashionable future.
2. Sandblasting treatment
This is a common surface treatment process for stainless steel processing, which mainly uses the power obtained by compressing air. The high-speed spray beam sprays the material onto the surface of the workpiece to be treated, causing a shape change on the outer surface of the workpiece.
Sandblasting is mainly used in engineering and surface technology, such as improving the viscosity of adhesive parts, optimizing machining surface burrs, cleaning, and surface matte treatment, all of which have a significant effect. This process has a much better effect than manual polishing. The surface structure after sandblasting treatment is uniform, which can create the low-key and durable characteristics of the product, and the production and processing efficiency is high. Manual polishing can create rough surfaces, but the speed is too slow, while chemical solvent cleaning can clean surfaces that are too smooth and not conducive to coating adhesion.
3. Chemical treatment
This process mainly uses a combination of chemistry and electrochemistry to treat a layer of stable compounds generated on the surface of stainless steel. For example, the common electroplating in our daily life is a type of chemical treatment.
Chemical treatment mainly relies on individual or mixed acidic solutions, cationic solutions, etc. for rust removal. Afterwards, a protective film is generated on the metal surface through methods such as chromate treatment, phosphate treatment, anodizing, and blackening. This process is mainly used to create complex pattern effects, create retro or modern design requirements.
4. Surface coloring
The surface coloring process of stainless steel can bring different colors to stainless steel, making the metal more rich and colorful. Coloring not only enriches the appearance of stainless steel, but also effectively improves the wear and corrosion resistance of the product.
The commonly used surface coloring methods include chemical coloring, electrochemical oxidation coloring, ion deposition oxide coloring, high-temperature oxidation coloring, and gas-phase cracking coloring, among others.
5. Surface drawing treatment
Metal wire drawing is a common decorative method in daily life. It can be manufactured into several types such as straight lines, threads, ripples, random lines, and spiral lines. This surface treatment has the characteristics of good hand feel, delicate luster, and strong wear resistance. It is widely used in electronic devices, household appliances, mechanical equipment, and other fields.
6. Spray coating
There is a significant difference between stainless steel spraying and coloring treatment. Due to differences in materials, some spraying may damage the oxide layer on the surface of stainless steel. However, some spraying techniques can be used to achieve different colors of stainless steel products, and different spraying methods can also be used to change the feel of stainless steel.
