Different stainless steel surface treatment processes can make the same material to highlight different visual effects and feature features. From the perspective of the design, you need to understand the surface treatment process of the following seven stainless steel below.

1.PVD process

PVD (Physical Vapor Deposition) - Physical Vapor Deposition: Refers to the process of transferring material transfer using a physical process, transferring atom or molecules from the source to the surface of the substrate. Its role is possible to spray certain particles with special properties (strength, wear resistance, heat dissipation, corrosion resistance, etc.) to a parent with lower performance, so that the mother has better properties. Basic method of PVD: Vacuum evaporation, sputtering, ion plating (hollow cathode ion plating, thermohenic ion plating, arc ion plating, active reactive ion plating, radio frequency ion plating, DC discharge ion plating).


2. Sandblasting process


The blasting is dynamic to form a high-speed injection bundle to form a high-speed injection beam to spray the spray (copper mine, quartz sand, diamond sand, iron sand, sea sand) high-speed to the surface of the workpiece, and changes the outer table or shape of the surface of the workpiece.


Sandblasts have strong applications in engineering and surface crafts, such as increasing adhesive viscosity, decontamination, and optimizing surface burrs, surface matte treatment.

The sandblasting process is harmful and efficient than manual grinding. The stainless steel treatment of this method is characterized by the low-key and durable characteristics of the product. Let's take a few examples to look at the effect of sandblasting process:

3. Chemical process

Chemical treatment is a collective expression of a stainless steel surface to form a stable compound method using chemical or electrochemical treatment. Electroplating as usually said is electrochemical treatment.

The acid solution, anode dissolution (electrolytic) or the like is used alone or in mixed, using a phosphate treatment, chromate treatment, hair black, and anodizing the metal surface to generate a layer of protective film, all of which belong to this method. This method can achieve complex pattern effects, build retro or modern design needs.

4. Mirror Process

Stainless steel mirror treatment, simply, polishing the stainless steel surface, and polishing is divided into physical polishing and chemical polishing. It is also possible to partially polish the stainless steel surface, and the polished grade is divided into ordinary polishing, ordinary 6K, fine grinding 8K, super fine grinding 10K effect. The mirror gives people a high-end simple, fashionable future.


5. Coloring Process


Stainless steel coloring not only gives various colors of stainless steel products, but also increases the color variety of the product, but also improves product wear resistance and corrosion resistance. There are many kinds of surface coloration, and the system is divided into: 1, chemically oxidation method; 2, electrochemically oxidation method; 3, ion deposition oxide coloring method; 4, high temperature oxidation method; 5, gas phase cracking color law.

6. Brushedraft

A technique that is commonly used in brushed stainless steel products can be made according to decoration needs, made into straight grain, chaos, threads, ripples and rods. Stainless steel surface brushes gives people super good feel, delicate gloss, wear-resistant surface, and personal texture. There is widely used in electronic equipment, kitchen appliances, and machinery.


7. Spraying process stainless steel spraying is different from the coloration mentioned above, and some paints may undermine the stainless steel surface oxide layer depending on the material. However, spraying can achieve different colors of stainless steel products with a simple process, or use different paint to change stainless steel feel. The stainless steel cup like our daily use will use sprayed processes.
