Surface Treatment: Exposing Metals to New Possibilities
Surface treatment is a process which changes the physical, chemical, or mechanical aspects of the surface of a product. By altering the surface of a material, it can be exposed to new possibilities and applications. In metalworking, surface treatment is used to enhance the properties and performance of metals, usually for the purpose of corrosion protection or improved wear resistance. In this essay, the explanations of the various surface treatments and their advantages will be discussed.
Corrosion protection is the main reason for surface treatment. By adding a protective layer to the metal, corrosion can be prevented. For example, galvanization is a process used to protect steel or iron from corrosion. In this process, zinc is applied to the metal in order to form a protective layer around it. This layer can last for up to several decades, and prevents the formation of rust. There are also various chemical processes which can help prevent corrosion, such as phosphate coating, anodizing, and chromating.
In addition to corrosion protection, surface treatment can also be used to enhance the appearance of the metal. For example, electroplating is a technique that is used to add a layer of metal onto the surface of another, in order to give it a desired finish. The metal can be coated with chrome, copper, gold, or any other type of metal. This process is often used for decorative purposes, as it gives the metal an aesthetically pleasing finish.
The performance of metals can also be improved through surface treatment. For example, grinding is a process which is used to remove the surface material from the metal in order to create a smoother and more even surface. This can improve the strength of the metal and make it easier to work with. Other processes, such as shot peening, can also be used to create a more durable surface by making it harder and more resistant to scratches and other types of wear and tear.
In conclusion, surface treatment is an important process used in metalworking. By altering the surface of the metal, it can be made more resistant to corrosion, given a better aesthetic finish, or made more durable. These advantages make surface treatment an essential part of creating products of the highest quality.
