The femtosecond laser produces an oxidation formation on a titanium alloy surface. Varying colors can be achieved by creating oxide layers of different thicknesses. Electrolysis is another technology for metal coloring, but due to the precision of the laser we can selectively color the titanium with high speed and accuracy.
Numerous cosmetic, industrial, and automotive applications exist for “colored titanium.” It is utilized in jewelry, watchmaking, medical device and tool marking. Moreover, titanium is not the only metal that has this property. Though not as vibrant, similar effects can be achieved on stainless steel, copper, silver, gold and some other metals.

Applying for Industries
A feasibility study is composed of several steps, including researching methods for fabricating micro-structures, fabricating a micro-structure prototype, measuring and aligning the prototype with technical requirements, and finally preparing a study report.
