Permanent Labelling With Lasers This whitepaper will discuss the laser marking systems, examples of its use in the manufacturing industry. Laser marking device features, requirements and the technology behind different marking methods will also be presented.
Influence Of Laser Hardening By Round, Profiled And Oscillating Beam On The Increase Of Service Life Of Machine Parts The developed technology of broadband laser hardening with a fibre laser beam using IPG 2D scanners will allow expanding the range of parts. The width of the hardening zone of 15–50 mm in one pass allows processing the seats of the centre shafts of various mechanisms and machines for rolling and sliding bearings. In addition, this technology can be used to strengthen bending and other dies with a depth of the hardened layer of 2.5 mm.
Ab Initio Modeling Of Atomic Tungsten Clusters Nucleation With Laser Surface Alloying Of Ceramics In the article are discussed the mechanisms of nucleation formation of tungsten atomic clusters after laser impact that lead to surface reconstruction and the formation of new material properties. The results will be useful for definition of optimal modes during laser doping.
