The role and application of titanium anodizing
Although titanium itself has a good high temperature, low temperature, anti-acid, anti-alkali, and high strength, low density, stable chemical properties. However, the surface modification of titanium in the wear resistance, hardness, corrosion resistance, biological affinity still cannot meet the practical needs, it is necessary for the titanium surface treatment, and titanium anodic oxidation is one of their Kind of craft
Titanium anodic oxidation process
Titanium anodic oxidation principle is the use of titanium in the ionic solution of electrolysis, which formed in the cathode titanium oxide film process, because of its operating parameters easy to control, and can be adjusted by electrolysis voltage to achieve beautiful and has practical application The color of the value, as the voltage slowly rises, the surface of the titanium will form brown, purple, blue, light blue, gold, pink, grass green, green, black, and various other colors as if it were a rainbow.
Titanium anodizing applications are mainly concentrated in the following industries:
1, the medical industry, titanium metal is now recognized as the closest human skeleton of the metal material. It is called "bio-metal." This is mainly determined by its excellent corrosion resistance, bio-affinity and low modulus of elasticity. Although titanium has the above excellent biological properties, human tissue cannot be attached after being implanted in the human body for a period of time On top, losing its function as a human skeleton. However, the titanium anodization process can address this issue well. First of all, since the main component of the oxide film formed by titanium anodization is titanium oxide, the titanium oxide is non-toxic and non-repellent to the human body. Second, the oxide film formed by titanium anodization is porous and more bio-compatible, which provides a stronger and stronger adhesion to the human tissue and thus plays a key role in the intermediate layer of the oxide film , To solve the human body tissue can not be effectively attached to the titanium implant; Second, the titanium anodized film can effectively inhibit the titanium implant components harmful to human precipitation, but also significantly improve the corrosion resistance of titanium. Because of the exceptional biological properties of titanium anodized film, the titanium alloy implanted in the body must be anodized.
2. In the field of aviation industry, reducing the weight of aero-aircraft becomes an important way to bear the brunt of energy-saving and emission reduction because the aviation industry needs more fuel for pushing the same weight than road traffic, compared with road traffic Titanium and titanium than the high strength just to play this task, so now the aviation industry in titanium screws, titanium nuts, titanium bolts and other titanium products more and more use, and aircraft, especially aircraft, aircraft, its usual maintenance Maintenance is particularly important. Titanium products due to sticky mold, making titanium screws and titanium nuts are easy to bite together, leaving the screws cannot be removed. Titanium anodized film can effectively solve this problem, due to the presence of the oxide film, making the titanium surface is equivalent to a layer of lubricant film, thus the maintenance and replacement convenience.
3, chemical, marine applications, chemical and marine contact due to the high acid and alkaline environment, and titanium products made of titanium anodic oxide film will significantly improve the corrosion resistance of titanium, titanium products are more difficult to be Corrosion, and in the field of ships to effectively inhibit the marine microorganisms attached to the surface of titanium products, thereby enhancing product appearance.
With the development of science and technology as well as the improvement of people's living standards, people's understanding of titanium will be more and more in-depth, titanium will be more and more used in industry and daily life, and titanium anodizing will get more and more The more attention and application.
