Types of Metallic Coatings and How to Use Them

Are you fascinated by metallic coatings? 

Metallic coatings come in many different finishes and are in a variety of industries. Whether you are a hobby machinist or a business looking to add some shine and protection to your protection products, metallic coatings can be a good option for you.

If you want to know more about the different types of metallic coatings, keep reading. In this article, we are going over the most popular types of metallic coatings and their uses.

Electroplating

Electroplating is the process of using an electric current to coat a delicate metal such as copper, or precious metals such as silver and gold. Electroplating gives cheap metals an expensive look while also giving them a sacrificial barrier to the metal below its layer.

Electroplating is also used to me things rust-resistant or to make plastic have a metal look. Electroplating is used in a wide range of products such as car parts, art, jewelry, tools, and architecture.

Chrome Plating

Like electroplating, chromium plating also uses an electrical charge for its layers. When adding chrome plating, the manufacturer uses chromium anhydride to the electrical charge.

This process triggers a chemical reaction in which the chromium deposits onto the surface of the object. Chrome plating is popular among car enthusiasts for wheels, cylinders, pistons, and exterior trim.

Galvanizing

The most widely used method for protecting metal against corrosion is galvanizing. This process includes applying a thin coat of zinc to a base metal such as stainless steel or aluminum.

Steel and aluminum are susceptible to corrosion and oxidization. Using this method will protect the metal from this and also add some scratch resistance. Galvanized metal is used in appliances, work tools, car components, and metal art.

Anodizing

Anodization is the process of converting a metal surface into a corrosion-resistant finish using an electrochemical process. This process is done by taking the metal such as aluminum and passing a current through an electrolytic solution.

This creates a build-up of aluminum oxide to thicken up at the surface thus creating an extra barrier of protection for the metal. Anodized metal commonly used for appliances, car components, architectural structures, and jewelry.

Platinum Plating

Platinum is popular for its aesthetic appeal and its durability. Platinum is rated as one of the strongest precious metals in existence. With that said, plating a thin layer of platinum over a less sturdy metal will give it some durability and corrosion resistance. 

Since platinum is a very sturdy type of metal, you won’t need too much of a coating for added protection. All you need is about 0.5 microns of thickness. 

If weight is an issue, using a platinum coating will give you more strength with less weight.

Metallic Coatings That Are Best For You

Selecting the best metallic coatings for your project is vital for protection and corrosion resistance. It’s best to try out different types of coatings on the substrate of your piece to ensure metal compatibility and aesthetic appeal.
