A Brief Guide on Metal Plating

1. A Brief Guide on Metal Plating If you're not familiar with metal plating, you may be surprised to learn that it has a wide range of applications—from the common, like decorative finishes and protective coatings, to the specialized, like corrosion-resistant coatings on pipelines. It's important to properly

2. choose a coating material for your application. The wrong material can end up being more harmful than helpful! For example, some materials just don't match well with certain conditions. For example, industrial environments may involve extreme temperatures or harsh chemicals. A material that doesn't resist temperature changes well may overheat in high temperatures and lead to premature failure from thermal stress. Similarly, a material that is not resistant to corrosive chemicals may corrode and fall apart prematurely in an environment where it will come into contact with these chemicals. That's why it's so important to choose the right coating for the right application! Electroplating is a process where the metals are deposited or fused onto another metal by an electric current. This process can be done in two ways: electrodeposition electrodeposition, electric current is used to deposit the desired metal on a conductive surface such as copper, nickel, zinc and others. The plating solutions are made from chemical compounds that yield positively charged ions (cations) such as copper, silver and gold. The metallic ions migrate through the solution to the negatively charged electrode and adhere to it. The second method is electroless plating; here a chemical compound is used to create a negative charge on the target surface. Then it is dipped in a solution containing positively charged metallic ions. When these ions come into contact with the negative surface they cling to it forming an even film of metal. and electroless plating. In

3. Metal plating has been used in industrial applications for hundreds of years. It has been a part of the manufacturing process since the earliest examples of metal processing when the only way to combat corrosion and wear was with an outer layer of another metal. Plating is an integral part of modern manufacturing, where it is used both for functional purposes, such as providing additional protection against corrosion and wear, and aesthetic purposes, such as providing a color or a mirror finish. Metal plating is used primarily for three reasons: corrosion and wear resistance, aesthetics, and functional purposes. Corrosion is one of the main enemies metal products have to face. If left untreated, metal will corrode away rapidly; this happens constantly to most metals in a natural environment due to oxidation and chemical reactions that occur between substances in the air or on the metal surface. To combat this problem, industrially plated metals are usually placed in an environment where they are protected from the air (a vacuum) or submerged in a chemical solution that will inhibit corrosion. These measures can prevent the rapid metal loss, but they do not stop it altogether—the lifespan of unplated metal parts is drastically shortened by corrosion even under ideal circumstances. The metallurgic processes known as plating and electroplating alter the surface of a metal object to give it an enhanced capability in a variety of areas. These processes are used on a wide range of products, from small electronics like cell phone cases and smartwatch bands to large

4. industrial machinery such as gears for cars or airplanes. Plating is also used in jewelry, to offer durability and aesthetic customization options. The surface of a metal is often damaged by contact with other metals or substances, such as certain chemicals. To combat this, plating and electroplating create a layer of another metal on top of the base metal. This layer then takes the point of impact so that the base metal can remain intact and functional. However, this does not always work perfectly—for example, if the base metal is not perfectly smooth or flat, to begin with; the plated layer may crack or peel off in response to stress on the product. Thus, it's important to consider what your product will be used for: if it's getting knocked around a lot, you might want to choose a thicker layer of plating material than if it will just be sitting there looking pretty. The process of plating metal involves three categories of metal plating chemicals: acids, bases and coatings. Acids are used to strip away the surface of the item being plated, while bases are used to clean it afterward, so they're generally not left in contact with the metal long after they've done their jobs. The most common coating is chrome, and it's also the most dangerous; cyanide compounds are used in its production. Cadmium is a toxic heavy metal, and cyanide compounds can release hydrogen cyanide gas when heated, making worker safety especially important for this procedure. Thankfully, there are other types of coatings that don't use cyanide compounds, such as gold and silver. Solvents may be used in surface preparation or cleaning after the plating process is complete. Benzene is one type that can cause cancer if exposed to large amounts over time; perchloroethylene (perc) is
