Introduction
Surface treatment is a process by which the surface of a material is altered to improve its performance or aesthetic qualities. The process is employed on metals and nonmetals alike, and can be used to make materials stronger, corrosion resistant, better-looking, longer lasting and more flexible. The methods employed for surface finishing can range from simple mechanical processes like sanding and grinding to complex chemical treatments like electroplating and oxidation processes.
The process of surface treatment is usually divided into two main categories: mechanical and chemical. Mechanical surface treatment usually involves processes such as grinding, blasting or sanding to either smooth the surface or create grooves or surface textures. Chemical treatments involve a variety of surface treatments such as electroplating, galvanizing and anodizing. These processes help to protect the metal from corrosion and to give it a longer life span.
Surface Treatment Procedure
Surface finishing is composed of many different steps, which depend on the type of material being treated and the desired outcome for the surface. In general, however, surface treatment processes typically involve the following steps:
1. Preparation: The first step usually entails cleaning the surface to be treated with a solvent or degreaser, and then removing any impurities or contaminants. This step prepares the surface to be treated and is critical to ensuring the success of the entire procedure.
2. Masking: This step involves sealing off any areas of the surface which are not to be treated. This helps to protect these areas from damage during the treatment process.
3. Deburring: Any sharp edges or rough spots are usually sanded or cut down to create a smooth edge. This step is especially important for materials which have been machined, as the machining process can create rough or unfinished surfaces which need to be smoothed out for a better finish.
4. Application of Treatment: The type of treatment applied will depend on the material and the desired outcome. These treatments can range from simple mechanical processes like sandblasting or grinding, to complex chemical processes like electroplating.
5. Inspection: All surfaces should be inspected for any defects or problems before proceeding to the next step.
6. Finishing: After the desired surface treatment has been applied, the surface must be polished or buffed to create a smooth finish.
Benefits of Surface Treatment
Surface treatment is important for a variety of reasons. It can be used to improve the appearance or performance of a material, protect it from corrosion and make it more durable. It can also be used to create surfaces which are easier to clean or add visual appeal.
Not only can surface treatment be used to improve the performance of a product, but it can also be used to reduce costs by preventing the need for expensive repairs or replacements. By performing routine surface treatments, companies and individuals can prevent corrosion, wear and tear and other damage which can occur over time and effectively extend the lifespan of a product.
Conclusion
Surface treatment is a process which is employed on a variety of materials from metals to plastics to improve the performance and aesthetic qualities of a product. The process is divided into two main categories, mechanical and chemical, and involves a variety of steps from preparation and masking to application and inspection. By performing surface treatment, companies and individuals can not only improve the performance of a product, but also help to reduce costs associated with repairs and replacements.
