The type of mark required by the medical device industry is called an annealed mark. Annealing does not remove or engrave the material. Instead, annealed markings are created by using the heat of the laser beam, and bringing the workpiece close to its melting point. As a result, the laser beam creates the desired dark oxide layers on the workpiece surface. The result is highly dependent on the composition of the material and the resulting oxide.
Since it does not remove any material, when touching an annealed mark you should not be able to physically feel the mark itself. The laser energy needed to build up this oxide layer generally weakens the passive layer on the marked surface and can cause the compounds to migrate to the surface. So, this is why annealing is very instrumental in the medical industry. It prevents pathogens from finding a place to harbor bacteria and causing future infections in implants. Laser annealing for medical devices can be performed on ferrous metals, titanium, and particularly medical grade stainless steel.
