Laser Annealing
Laser annealing, also known as carbon migration, is a precise technique used to create smooth, high-contrast surface marks on various metals.
- 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
What Is Laser Annealing?
Laser annealing involves applying heat just below the material’s melting point to produce a superficial heat temper. This brings the carbon to the surface, resulting in a smooth, high-contrast surface mark. The typical outcome is a jet-black appearance, making it ideal for medical marking on stainless steel and titanium, where minimizing surface disruption is critical.
Beyond creating black markings, laser annealing can also produce various color markings on stainless steel and titanium. Most laser annealing tasks can be achieved with nanosecond fiber lasers. However, we also offer UV and picosecond lasers to reduce the heat-affected zone on the material surface, ensuring precise and high-quality results.
Best Materials for Laser Annealing
High-contrast surface markings through precise control over laser power and speed.
Laser Annealing Steel and Stainless Steel
Laser annealing is an advanced material processing technique used to create high-contrast markings on metals like steel and stainless steel. By using a laser beam, the surface of the metal is heated to a precise temperature, causing a controlled oxidation reaction that changes its color without removing any material.
Laser Annealing Titanium
Laser annealing titanium is a precise and efficient process that involves using a laser to heat the metal’s surface to a controlled temperature. This process creates a thin oxide layer that results in a visually distinct, durable, and corrosion-resistant mark. Unlike traditional marking methods, laser annealing does not remove any material or alter the surface’s texture, making it an ideal choice for applications where maintaining the integrity of the titanium is crucial. This method is commonly used in industries such as aerospace, medical devices, and consumer products, where high-contrast and long-lasting marks are essential. The resulting marks are not only aesthetically pleasing but also capable of withstanding harsh environments and repeated sterilization processes.

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.
