Zinc Plating
Zinc Plating is a process used to coat metal surfaces, typically steel or iron, with a layer of zinc. This is done to protect the underlying metal from corrosion and to enhance its appearance. The plated surface acts as a sacrificial coating, meaning it will corrode before the underlying metal does, thereby extending the life of the coated object Some of the industries where zinc plating is applied include:
Automotive Fasteners
Mining Pressings
Rail Machined Components
Hydrogen De-Embrittement
Hydrogen de-embrittlement is an important step in the electroplating process. Embrittlement is what happens when various metals become brittle and fracture following exposure to hydrogen. Hydrogen embrittlement is often the result of the unintentional introduction of hydrogen into susceptible metals during metal finishing operations and consequently increases the risk of cracking in the material. The hydrogen de-embrittlement process should be carried out as soon as possible after electroplating.
Zinc-Nickel Plating
Zinc-Nickel Plating is a corrosion-resistant coating process that combines zinc and nickel to enhance the protective qualities of metal surfaces. This method is particularly valued in industries where parts are exposed to harsh environments as the nickel component enhances the overall corrosion resistance, especially in saline and acidic conditions.
Zinc Flake
Zinc Flake coating is a protective finishing process that applies a coating composed of zinc and aluminium. This method is particularly useful in environments where components are exposed to harsh conditions, such as automotive and industrial applications. Zinc flake coatings are more environmentally friendly than traditional plating methods and also eliminate the need for hydrogen de-embrittlement.
Zinc Phosphating
Zinc Phosphating is an ideal intermediate step in the metal finishing process that improves the adherence of other coatings. Heavy phosphate coatings are also used to provide corrosion protection for fasteners and other small components.
Electroless Nickel Plating
Electroless Nickel Plating is a chemical process that deposits a layer of nickel onto a substrate without the use of electrical current. This method relies on an autocatalytic reaction, where nickel ions in a solution are reduced to metallic nickel and deposited onto the surface of the part. Advantages include a uniform finish across the substrate, excellent corrosion resistance, good wear resistance and is extremely efficient at plating complex geometries and internal surfaces.
Aluminium Anodising
The anodising process produces a thick oxide layer on the surface of aluminium which is used to improve corrosion and wear resistance and can be done in a variety of colours.
Tin Plating
Tin Plating is a process that involves applying a thin layer of tin onto a metal surface. This technique is commonly used to enhance the properties of the substrate, providing various benefits in different applications, including corrosion resistance, electrical conductivity, manufacturing of electronic components and the food industry.
