Electroplated nickel provides a uniform, dense, corrosion-resistant nickel alloy protective layer with excellent wear resistance and chemical stability. It can also achieve uniform deposition on objects with complex shapes.
Electroplated nickel provides excellent corrosion resistance, although there is certain trade-off between hardness and corrosion resistance. High-phosphorus electroplated nickel usually offers better corrosion resistance.
The thickness of electroplated nickel is typically controlled by the concentration of nickel salts and the deposition time in the plating solution. Increasing the deposition time and concentration will increase the thickness of the coating.
Compared to other methods like anodizing and electroplating, chem-film treatment focuses more on forming a thin yet effective conversion coating to provide corrosion resistance and superior surface protection.
Chem-film treatment involves a chemical reaction between chemicals and the surface of aluminum alloys to form a conversion coating, enhancing the corrosion resistance and other properties of aluminum alloys.
Yes, chem-film treatment typically retains the conductivity of aluminum alloy while improving corrosion resistance.
The durability of corrosion resistance depends on the specific application environment and the application of the components. In some cases, chem-film treatment can provide long-term corrosion protection.
Chem-film is mainly used in aerospace, automotive, electronics, and other fields to improve the corrosion resistance of aluminum alloys, enhance conductivity, and provide aesthetic improvements.
Brushing is commonly applied to metals such as stainless steel, aluminum, and brass.
– Textured appearance: The texture formed by brushing is usually linear, giving the metal surface a uniform and textured appearance.
– Scratch resistance: brushing can create a subtle texture on the metal surface, helping to conceal or reduce some scratches or flaws, thus increasing the metal’s scratch resistance.
– Reduced reflectivity: Compared to smooth surfaces, the surface treated by brushing reduces reflection and glare, making it less prone to glare. – Texture enhancement: brushing gives the metal surface a unique texture, which helps to improve the appearance quality and perceived value of the product.
– Concealment of surface defects: Due to its textured nature, brushing can effectively hide some minor surface defects or unevenness in metal surfaces.
– Applicable to various metals: Brushing can be applied to various metals, including stainless steel, aluminum, brass, etc., and thus has been widely used in different products and applications.
Brushing creates a linear texture on the metal surface, giving it a uniform and textured appearance while also increasing scratch resistance.
The oxide film formed by black oxide treatment provides a certain degree of corrosion resistance protection. However, its effectiveness depends on the specific conditions of treatment and the type of metal. In extreme corrosive environments, further protective measures may be required.
