Surface hardening for Low Carbon Steel (A3k) by Yag: Nd Pulse Laser Thermal Activation
(Universitatea "Dunărea de Jos" din Galați, 2008)The paper is based on experiments for surface hardening on A3k (low carbon steel) samples using YAG:Nd pulse laser. A small x-y moving system conducted by PC was made for sample scanning, relative to fixed focused laser ... -
Surface Hardening Over 38MoCrA109 Steel by Yag:Nd Pulse Laser
(Universitatea "Dunărea de Jos" din Galați, 2008)Laser offers unique capabilities for high energy concentrations at small surfaces. Factors that have influences over interactions between laser beam and steel surfaces have very high control. Pulse laser YAG:Nd is usually ...
