ASTM F136 titanium alloy has excellent thermal stability and high strength, and is widely used in aerospace, defense cutting-edge technology fields and medicine. However, titanium alloys also have shortcomings, such as poor adhesion resistance, wear resistance, low electrical and thermal conductivity, difficult to withstand brazing. From the current research and application, its anodic oxidation is a proven method. Titanium alloy anodic oxidation film has a higher hardness, strength, corrosion resistance and wear resistance than titanium, and with the change of the thickness of the film layer, its surface can show a variety of colors, is the ideal decorative layer and protective layer.
Titanium crafts not only have the noble silver bright texture, and also in titanium crafts through the line of nitriding treatment into a golden yellow, anodic oxidation into (according to not pass the current, temperature, and chemical formulations are not the same) so that titanium crafts show a variety of brilliant colors (blue, yellow, brown, green, red, etc.) can also be used in acid corrosion engraving method of processing, the layering of titanium plate paintings is very strong. Titanium handicrafts, titanium plate painting, titanium pen, titanium crutches, titanium fishing rod, titanium chess, titanium jewelry (bracelets, tie clips, brooches) and so on, basically the precious metal can have handicrafts, can be made out of titanium.
At present, titanium alloy is the only metal that minimizes damage to the human body, precisely because of the minimal damage to the human body, and then be used for human joints, bones and other implantable raw materials. Titanium's excellent biocompatibility, the human body is completely non-toxic, harmless, non-allergenic, its appearance by anodic oxidation, the composition of the oxide film has antibacterial, not only light, high strength, corrosion-resistant, and easy to high-temperature disinfection, and then the titanium alloy has been made into a lot of titanium tableware and titanium handicrafts. Titanium chopsticks, is gradually recognized by consumers. Titanium tableware, generally titanium chopsticks, titanium spoons, titanium forks, titanium bowls, too pots and pans, titanium table knives and so on. A report said that ordinary household wooden chopsticks, bamboo chopsticks used for more than 3 months, will breed all kinds of mold, serious mold will also breed can induce liver cancer "aflatoxin". Many families use a pair of chopsticks for several years, and not many families have the habit of sterilizing them. Experts say that as long as the chopsticks are usually kept dry and regularly disinfected, there is generally no problem. At the same time, experts reminded, according to the use of chopsticks should be replaced at the right time, titanium chopsticks are a good solution to this problem, due to titanium oxidation, will produce "photocatalyst" effect, so the titanium chopsticks oxidized film will have antibacterial effect.
