Surface Treatment Terminology
Surface treatment or finishing is an important step in the production of many items, from automotive and aerospace components to everyday kitchen items. The purpose of the finishing process is to protect the item from damage or wear and can also provide aesthetic pleasure. Surface treatments can also be a way to show off a certain feature of the item or add it to a unique design.
Surface treatments are often referred to as finishing because they help improve the quality of the finished product. Depending on the type of treatment chosen, it can enhance the items durability, corrosion resistance, and even help define the items look and feel. Every surface treatment has its own set of features and characteristics that make it ideal for the project at hand.
Chemical conversion treatment is a general term that is used to describe a variety of surface treatments that involve the application of a chemical solution or coating to the surface. The purpose of chemical conversion treatment is to protect the surface of the item from corrosion, wear, and chemical damage. The most common type of chemical conversions are anodizing and phosphate coatings.
Anodizing involves the application of an electrolyte to the surface of the item. This electrolyte reacts with the metal to create an oxide layer. This oxide layer is extremely hard and tough, making it suitable for protecting against corrosion and wear. Anodized parts are often used in applications where the part needs to hold its shape and withstand extreme wear and tear.
Phosphate coatings are a type of chemical conversion treatment that involves the application of a compound of phosphorous and acid. Phosphate coatings form a protective film over the surface of the item, which helps to increase its resistance to corrosion and wear. Phosphate coatings are often used on automotive parts, as they can improve their overall performance and reliability.
Powder coating is a process in which a dry powder is applied to the surface of the item. The powder is then cured and baked, resulting in a hard, durable finish. Powder coating is often used in the automotive and aerospace industries to protect parts from corrosion and wear. It can also be used to add color, texture, or logos to the item.
Heat treatment is the process of heating an item to a high temperature in order to improve its strength and durability. Heat treating is often used to harden steel and other metals, making them more resistant to corrosion and wear. Heat-treated items can often be used in more extreme applications and are often used to make items suitable for higher operating temperatures.
Plating is the process of applying a thin layer of metal to the surface of an item. Plating is used to protect the item from corrosion, wear, and chemical damage. It is also often used to enhance the items aesthetics, as it can add color and texture to the item. The most common types of platings are chrome plating, gold plating, and nickel plating.
Surface treatment is an important step in the manufacturing process and is used to protect the item and enhance its look and feel. Depending on the type of surface treatment selected, it can increase the items durability, corrosion resistance, and improve its performance and reliability. For many projects, the choice of the appropriate surface treatment is essential for the items long-term performance and satisfaction.
