Nikkelbeläggningar

Nikkelbeläggningar, also known as nickel plating, is a surface finishing process that applies a thin layer of nickel onto a metal substrate. This is typically achieved through electrodeposition, where the object to be plated is immersed in an electrolytic solution containing nickel ions and serves as the cathode in an electric circuit. An anode, often made of nickel, is also present. When an electric current is applied, nickel ions from the solution are attracted to the cathode and deposit onto its surface, forming a uniform coating.

The primary purpose of nickel plating is to enhance the properties of the underlying material. Nickel coatings offer excellent corrosion resistance, making them ideal for protecting components exposed to harsh environments. They also provide good wear resistance, increasing the durability of the plated parts. Furthermore, nickel plating can improve the aesthetic appeal of an object, offering a bright, lustrous finish. It can also serve as an underlayer for other plating processes, such as chromium plating, to improve adhesion and prevent diffusion.

Nickel plating is widely used across various industries, including automotive, aerospace, electronics, and decorative applications. In automotive manufacturing, it protects components like exhaust systems and fasteners from corrosion. In electronics, it is used on connectors and printed circuit boards for conductivity and protection. Decorative nickel plating is common on faucets, hardware, and jewelry, providing a durable and attractive finish. The specific type of nickel plating, such as bright nickel, semi-bright nickel, or electroless nickel, is chosen based on the desired properties and application.
