Aluminum is the non-ferrous metal that is used in the greatest number of different applications, and it is anticipated that this number will continue to increase over the next few years. The use of aluminum in the manufacturing of other products made of aluminum is not only extremely common, but also comes close to reaching an absolute maximum. According to the data that is currently available, there are likely more than 700,000 different varieties. For instance, the requirements for the transportation and aerospace industries are very dissimilar to those of the construction and decoration industries. In today's article, I'd like to talk about the many different surface treatments that can be used on aluminum products.
1. Sandblasting (shotblasting)
The action of cleaning and roughening the surface of a metal by using the impact of a sand flow moving at a high speed in order to achieve the desired effect.
In the process of treating the surface of aluminum components with this method, it is possible to achieve a specific level of cleanliness as well as a distinct roughness on the surface of the workpiece. In addition to this, it has the potential to enhance the mechanical properties of the surface of the workpiece, which, in turn, enhances the fatigue resistance of the workpiece and increases the distance between the workpiece and the coating. Because of the adhesion, the coating film's durability has been significantly improved, and the adhesion also contributes to the coating's leveling and decoration in addition to improving the film's longevity.
2. the crowning achievement
A process that utilizes mechanical, chemical, or electrochemical action to reduce the surface roughness of a workpiece in order to obtain a smooth, bright surface. The goal of this process is to make the surface of the workpiece as shiny and smooth as possible. Surface finishing is another term that can be used interchangeably with surface finishing. There are a few primary types of polishing, the most common of which are mechanical polishing, chemical polishing, and electrolytic polishing. Polishing can also be broken down into a few primary categories. Aluminum components, after undergoing both mechanical and electrolytic polishing, can come very close to having the mirror effect of stainless steel. This is because mechanical polishing is more aggressive than electrolytic polishing. As a result of this process, we have the feeling that the world of the future will be extremely constrained and fashion-forward.
3. Painting with a Brush
As part of the manufacturing process, the process of brushing involves repeatedly scraping the aluminum plate out of the line using sandpaper. This is done during the process of brushing. Brushing can be subdivided into a few different categories, including thread brushing, spiral brushing, random brushing, and straight brushing. The brushing process makes it possible to see each individual minuscule silk mark, which gives the metal matte a fine hair shine and provides the product with a sense of both fashion and technology.
4. Utilizing a cutting technique with a high gloss
When using a diamond cutter to cut parts with a carving machine, the cutter is reinforced on the spindle of the carving machine, which rotates at a high speed (typically 20,000 revolutions per minute). Because of this, highlight areas will appear in localized spots across the surface of the product. There is a correlation between the rotational speed of the milling drill and the amount of light that is transmitted to the cutting highlight. If you increase the speed of the drill, the cutting highlight will become brighter; if you decrease the speed, the cutting highlight will become darker, and milling marks will be more likely to appear. Specifically, high-gloss cutting is used in the manufacturing of mobile phones such as the iPhone5, amongst other examples. Recently, manufacturers of high-end televisions have begun using a process known as high-gloss milling for the metal frames of their sets. This is a relatively recent development. In addition, procedures such as anodizing and wire drawing have contributed to the overall trendier and more technologically advanced nature of the TV.
5. Anodizing
The term "anodizing" refers to the process of oxidizing metals and alloys through an electrochemical reaction. When exposed to the proper electrolyte and certain process conditions, aluminum and its alloys will, as a result of an applied current, form an oxide film on aluminum products, which are referred to as anodes. This film protects the aluminum from further corrosion and oxidation. Anodizing is a process that can not only increase the surface hardness and abrasion resistance of aluminum, but it can also improve the appearance of aluminum and lengthen the amount of time that aluminum can be used for its intended purpose. In addition to this, it has become an essential component of the surface treatment of aluminum, which has led to it becoming the method that is utilized the most extensively and which has experienced the highest level of success.
