The surface treatment process of stainless steel forgings has the following methods: mechanical polishing: through mechanical grinding and polishing, the surface of stainless steel forgings is bright and smooth. Pickling treatment: The stainless steel forgings are treated in an acidic solution, which can remove the oxide and pollutants on the surface of the forgings, making the surface cleaner. Sandblasting treatment: The use of high pressure air to spray silica sand or other particles to the surface of stainless steel forgings, so as to achieve the effect of removing pollutants. At the same time, sandblasting can also increase the surface roughness of stainless steel forgings and provide better coating adhesion. Electroplating treatment: By electrolytic deposition of metal or alloy on the surface of stainless steel forgings to form a protective layer, improve its corrosion resistance. Common electroplating methods include chromium plating, nickel plating, etc. Chemical coloring: Use chemical methods to change the color of the surface of stainless steel forgings to increase the decorative effect. For example, oxidation dyeing, anode coloring and so on. Coating treatment: A special coating or paint is applied to the surface of the stainless steel forgings to protect the forgings. Common coating treatment methods include baking paint, spraying and so on. Ion nitriding treatment: The ion nitriding process is used to form a nitriding layer on the surface of stainless steel forgings to improve its hardness and wear resistance. The choice of surface treatment method depends on the specific requirements and application fields of stainless steel forgings, and it is necessary to consider factors such as physical properties, chemical properties and appearance effects. At the same time, when performing surface treatment, it is also necessary to pay attention to the corresponding environmental requirements and operating norms.
