Stainless Steel Common Surfaces
Home > Stainless Steel Common Surfaces >There are a variety of common surface treatments for stainless steel, the main purpose of which is to improve the appearance, corrosion resistance, wear resistance or other properties of stainless steel. The following are some common surface treatment methods for stainless steel.
Mechanical treatment
Through grinding or brushing the surface of stainless steel to form a line pattern, which can be straight, chaotic, corrugated and so on. It has good decorative effect and is commonly used in home appliances, elevators and other surfaces.
The surface shows a uniform matte effect, reducing light reflection and appearing soft. Commonly used in tableware, kitchenware, etc.
Through mechanical polishing (such as grinding wheel, polishing wheel) or chemical polishing, make the surface bright as a mirror. According to the degree of brightness can be divided into ordinary polishing, 6K, 8K (mirror), 10K and so on. Mirror effect is commonly used for decoration, reflectors, etc.
The use of compressed air driven abrasive high-speed jet to the surface of the stainless steel, forming a uniform sand effect, can remove surface oxidation, rust, etc., and increase the surface roughness, conducive to subsequent painting.
Put the stainless steel workpiece and abrasive into the roller or vibratory disk, and grind it by rolling or vibration to remove burrs, chamfering, polishing and so on.
Chemical treatment
Use acidic solution to remove the oxidized skin and welding slag on the surface of stainless steel, so that the surface shows the metal color.
Stainless steel is immersed in passivation solution to form a dense oxide film on its surface to improve corrosion resistance.
The use of electrochemical methods to make the surface of stainless steel dissolved, to achieve the polishing effect, you can get a smoother surface than mechanical polishing, and is not easy to produce stress concentration.
Surface coloring
Through chemical methods to make the surface of stainless steel to form a layer of colored oxide film, you can get a variety of colors, such as titanium, rose gold, champagne gold and so on.
Physical vapor deposition, a layer of metal or compound film on the surface of stainless steel, can obtain a variety of colors and excellent abrasion resistance, corrosion resistance.
Other treatments
Various patterns or designs are embossed on the surface of stainless steel through molds to increase the decorative effect.
A special coating is applied on the surface of stainless steel to reduce fingerprint residue and keep the surface clean.
Summarize: The choice of which surface treatment depends on the specific requirements and application scenarios. For example, if you need high gloss decorative effect, you can choose mirror polishing or PVD coating; if you need to improve corrosion resistance, you can choose passivation or electrolytic polishing; if you need to increase the surface roughness, you can choose sandblasting.
