Stainless steel surface treatment is to improve the appearance and performance of the stainless steel surface. Common stainless steel surface treatment processes include the following:
1. Mechanical polishing: Mechanical polishing is to make the surface of stainless steel smooth and flat by grinding and polishing process, using abrasives and polishing materials of different particle sizes, removing the oxides and loose parts on the surface, and obtaining a high-brightness surface.
2. Pickling: Pickling is to treat the surface of stainless steel with acidic solution (such as nitric acid, hydrochloric acid, sulfuric acid, etc.) to remove the oxide scale, welding slag and carbon stains on the surface. Pickling can restore stainless steel to its original uniform brightness and improve the corrosion resistance of stainless steel.
3. Electrochemical polishing: Electrochemical polishing is to use electrochemical principles to perform electrolytic treatment in a specific electrolyte to remove the roughness and oxides on the surface of stainless steel and obtain a high-brightness surface.
4. Sandblasting: Sandblasting is to spray abrasives (such as quartz sand, corundum, etc.) onto the surface of stainless steel through high-speed airflow to generate impact and friction, remove dirt, oxide scale and burrs on the surface, and obtain a surface with uniform roughness.
5. Electroplating: Electroplating is to form a layer of metal plating on the surface of stainless steel to provide additional corrosion resistance and aesthetics. Common chemical plating includes chrome plating, copper plating, nickel plating, etc.
6. Coating: Coating is a layer of paint or film applied on the surface of stainless steel, which can increase the color and decorative effect of stainless steel while providing additional corrosion resistance and wear resistance.
The above are common stainless steel surface treatment processes. The selection of appropriate surface treatment processes depends on the purpose and requirements of stainless steel materials. Each process has its advantages and disadvantages, and needs to be selected according to actual needs to achieve the best surface effect and performance.
