In electroplating, a more-expensive metal is plated deposited in a thin layer onto the surface of a cheaper metal by electrolysis. Before plastic auto bumpers became popular, chromium metal was electroplated onto steel bumpers. The following diagram shows the electroplating of silver onto a teapot.
How does this amazing process work? Let& 39;s take a closer look Photo: Electroplating in action—an exhibit at Think Tank the science museum in Birmingham, England . These two forks are the electrodes and the blue solution copper sulfate is being used to copper-plate one of them.
In one form of electroplating, the metal to be plated is lo ed at the anode of the circuit, with the item to be plated lo ed at the hode. Both the anode and hode are immersed in a solution that contains a dissolved metal salt—such as an ion of the metal being plated—and other ions that act to permit the flow of electricity through ...
The Electroplating Process In 8 Steps. The electroplating process is a complex procedure and while there are several different techniques, this info-graphic may make the process a little easier to understand: The Plating Process. 1.
The Electroplating process is quite similar to the Electroforming process: both are a form of additive manufacturing, and both work through an electro-deposition process. In Electroplating, both an anode and a hode the metal part to be coated are immersed in an electrolytic bath that is composed of a solution of salts, including the metal ...
The diagram of the industrialized process for treatment and reuse of electroplating waste water 21 . The IBMS-CP system presented relatively stable performance during a 17-month operation 21 . Membrane cleaning was conducted every 3 months and can recover the separation performance of membrane efficiently.
Electroplating is a popular metal finishing and improving process used in a wide range of industries for various appli ions. Despite the popularity of electroplating, however, very few outside of the industry are familiar with the process, what it is and how it works.
Zinc electroplating is one of the most popular methods that is used all around for the purpose of electroplating. It is a very cost-effective process, and is mostly used to provide a protective coating to metallic substances such as nuts, bolts, fasteners, automotive parts, and many other hardware items.
