By applying heat or electricity one may unleash its refractive properties by inducing various oxide thicknesses on the material surface. The resulting titanium oxide causes an optical interference with a purity and vivacity much the same as witnessed in the luminescent colors of oil on water, a peacock's feather, or a rainbow.
The colors are directly related to time and voltage. This process is called anodization. Titanium is a reactive metal that can be anodized in different colors by electrolysis or thermal treatment. Unfortunately this type of surface treatment is not permanent.
An anodized titanium ring would look good initially, but can appear scratched and discolored with wear. Anodization is just an oxidation layer on the metal, so the color is more an optical illusion. It can just be the friction it encounters, or your body's natural acidity that wears the oxidized layer away. It will not hurt you, it is not dangerous.
It's just the nature of anodization. How quickly the anodization wears off depends on exposure. You can get piercings on any part of the body with anodized titanium, and it still is safe. Pros: There are many benefits to anodized titanium. The other advantage is that the process ends up forming a smoother surface. Additionally, with anodized titanium, you have a wider variety of colors and unique patterns to chose from. Even with that, the biocompatible and hypoallergenic nature of titanium, anodized or not, makes it safe for those with sensitive skin to wear.
There are a lot of positive things about getting anodized titanium. You get to have stylish jewelry, all the while enjoying its hypoallergenic nature.

The most common anodizing processes on aluminium use chromic acid, sulfuric acid or oxalic acid Wernick et al. Other acids, such as phosphoric acid and boric sulfuric acid mix, are now used in the market for anodizing in the aerospace industry.
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. Anodized titanium is used in a number of industries such as the medical and aerospace industries.
The process of anodizing gives titanium all the advantages of hardening and coloring without changing the metals mechanical properties. Titanium itself is an extremely hard, durable metal used in many applications.
The bottom line is that anodized titanium is very durable against the elements but not against friction or scratches — just like many other kinds of finishes. With proper care, your anodized titanium jewelry should last a lifetime. Titanium anodizing is an extremely cool and rewarding project that is very easy to do at home.
Anodizing is used industrially for enhanced corrosion resistance on metals like aluminum. Since the entire range of color for the titanium oxide layer is within 25 billionths of a meter a nanometer is 1-billionth of a meter , it is little wonder that the process requires careful precision and high-quality anodizing equipment to reach the best results. It should be noted that not every color can be produced with titanium anodizing.
In particular, red anodized titanium is not possible due to the physics of the optical interference phenomenon. The nearest available colors to red would be magenta, rose reddish violet or purple. In Type 3 color anodizing, a titanium part is immersed in an electrolyte solution.
The most common chemistry uses trisodium phosphate TSP , forming an alkaline solution; however, there are many options. The chemistry serves to provide ions for the electrolytic process, but it does not directly affect the titanium surface. The electrical part of the anodizing process requires a specialized rectifier , an electrical device that converts alternating current AC to direct current DC.
The rectifier allows you to regulate the voltage to a level that you specify and to control the amperage. In titanium anodizing, the voltage dictates the color. The volt range for color titanium anodizing is between 15 and volts. A bronze color, with the thinnest oxide layer, can be achieved with about 16 volts.
A green color, with the thickest oxide layer, can be achieved with volts. In contrast, the amperage dictates the time required. By increasing the amperage, the oxide layer forms more quickly. But the increased amperage carries a risk of inconsistency in color output, because it can become too difficult to stop the oxide layer buildup at the correct color. Product size drives the amperage; typically, the larger the product, the more amperage is used.
Best Technology and its partners have developed custom chemical blends of solutions and electrolytes that greatly increase the manufacturing yield of this process, which are not offered by anyone else in the industry.
The chemistry for a titanium anodizing line includes both cleaning and electrochemical electrolytes. For manufacturers looking to take their titanium color anodizing in-house and build their own Type 3 color anodize line, here is an example of process steps:.
Surface preparation , also called anodize prep, is crucial for achieving consistent color for titanium. The titanium surface must be prepared in a way that supports the even distribution of the oxide layer.
Anodize prep requires removing a thin layer of material to create a uniform surface for color anodizing.
