What is black laser annealing?

Black laser annealing is a printing technique that uses laser irradiation to heat up metal surfaces and form oxide films that appear as letters printed in black*. In contrast to traditional techniques involving metal surface etching, the absence of depressions or burrs keeps surfaces level. This makes black laser annealing the best printing technique for target objects such as bearings that require high surface precision.
*Black laser annealing may not be possible with certain materials.
