Plating Basics

Plating is a common process used to improve the properties of metal surfaces and to protect substrates from corrosion and wear. It involves the deposition of metal particles or metal-containing compounds on the substrate. Plating can be used to create a decorative finish, modify the electrical, optical, thermal, and mechanical characteristics of a surface, and reduce friction. It can also be used to implant custom materials into the surface.

Plating is a multistep process. The first step is to prepare the surface of the substrate, which may include cleaning, etching, and grinding. The second step is to apply the metal or metal-containing components to the surface. This is usually done through electroplating, which involves passing an electrical current through a bath containing the metal or metal-containing components. This results in the deposition of the metal or metal-containing components on the surface of the substrate.

Once the metal or metal-containing components are deposited on the surface of the substrate, there are several things that may happen to them. The metal or metal-containing components may become embedded in the substrate, forming a bond between them and the substrate. Alternatively, they may become bonded to the substrate through diffusion, a process by which atoms move from one material to another.

Once the plating process is complete, the substrate may need to be heat treated to strengthen the bond between the substrate and the metal or metal-containing components. Heat treatments may involve baking, annealing, or hardening.

Plating is widely used in many industries, including electronics, automotive, medical, and aerospace. Electronics applications involve plating circuits and chips, while automotive applications involve plating car parts, such as wheels and brake drums. Medical applications involve implantable devices, and aerospace applications involve plating aircraft parts.

Plating is a versatile process that can be used to improve the appearance, performance, and durability of a wide range of components. In order for plating to be successful, however, it is important to follow all of the steps carefully, as improper preparation or treatment can lead to inefficient plating or even damage to the substrate. A thorough understanding of the process is essential to producing satisfactory results.

Electroplating is a process of metal plating that uses an electric current to reduce dissolved metal ions onto a solid surface. It is a process of applying a thin layer of metal to an object to give it a shiny and metallic look.

Electroplating is commonly used in jewelry, coins, car and motorcycle parts and commercial products. Electroplating can also be used to coat a part or device in a very thin but incredibly durable layer of metal to provide an extra level of protection.

The process begins by preparing the surface to be plated by either polishing the object, or etching it with a chemical. Then the object is cleaned, to remove any dirt, debris or oils which can interfere with the plating process, and that’s done by immersing it in a mild acid.

The next step is to attach a negative terminal to the object and to the cathode of an electrolyte cell, with the positive terminal connected to the anode. An electrolyte, usually a salt-based solution, is then added to the cell, and the current is activated. This causes the dissolved metal ions to plate onto the surface of the object.

The last step is to rinse the object in clean water to remove any excess plating solution, and then evaluate it for quality.

In conclusion, electroplating is a great way to make metals last longer and to give them a beautiful, glossy finish. It is a simple process that can enhance the appearance and performance of many objects, from jewelry and coins to car parts and commercial products.
