Laser annealing or carbon migration results in a smooth, high-contrast surface mark.
- Annealing is a common technique for creating black surface marks on stainless or titanium medical components.
- Annealing can also be used to create color marking on steel, stainless, and titanium.
Laser annealing or carbon migration is created by applying heat, just below the melting point, to the surface of the material to produce a superficial heat temper, resulting in a smooth, high-contrast surface mark. This mark is typically jet black in appearance and is common for medical marking on stainless and titanium where minimizing surface disruption is paramount. In addition, annealing can be utilized to create various color markings on stainless and titanium. Most annealing can be accomplished with nanosecond fiber lasers; however, we also offer UV and picosecond lasers for reducing the heat-affected zone on the material surface.

The Absolute Best Customer Service Around
I’ve learned how awesome laser marking is! The new station ‘Laser Marking’ is creating a lot of buzz around our shop floor and in our offices and we are very happy with the performance of the EMS400. … Everyone can’t believe how fast it is.
I have been nothing but pleased with the entire process and relationship I have had with Tykma. I bought a Minilase a couple years ago and everything went off without a hitch.
The TYKMA Minilase 20W fiber laser has been a great asset for us. We were able to quickly migrate our production from older laser technology to the Minilase. It produces a higher quality mark in less time.
