Laser Annealing

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-steel or titanium medical components
  • Annealing laser marking can also be used to create color marking on steel, stainless steel, and titanium

About Annealing Laser Marking

Laser annealing or carbon migration is created by applying heat, just below the melting point, to the surface of a material to produce a superficial heat temper, resulting in a smooth, high-contrast surface mark. This laser annealing machining mark is typically jet black in appearance and is common for medical marking on stainless steel and titanium where minimizing surface disruption is paramount.

In addition, annealing can be utilized to create various color markings on stainless steel and titanium. Most laser 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 for 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.

Moataz Ibrahim, Protocase Incorporated

I have been nothing but pleased with the entire process and relationship I have had with TYKMA Electrox. I bought a Minilase a couple years ago and everything went off without a hitch.

Jeff Forbush, Owner, 4Bush Weapons Systems

The TYKMA Electrox 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.

Benefits of Utilizing Laser Annealing

Laser annealing is a process that results in high-quality products, as you can mark parts with low distortion. In addition to offering quality results, you’ll reap benefits that include:

  • Versatility – Laser annealing machining offers the capability to produce various colors aside from black, including blues, browns, and yellows.
  • Reliability – Resistant to fading, the annealing process reduces warping or distortions while making the object stronger. Since the material is only heated and cooled, this process is very reliable. Plus, laser annealing offers the ability to retain the original properties and shapes of materials you are working with.
  • Consistency – Uniform heating processes are used in this process, which produces consistent results and helps reduce issues.
  • Cleanliness – No chemicals are required in annealing laser marking, making it a very efficient and clean process.

FAQs on Annealing Laser Marking

What materials are ideal for laser annealing?
