Nanostructured Surface for 38MoCrAl09 Steel by Nitriding in Nitrogen Atmosphere and YAG:Nd Pulse Laser Activation
Résumé
YAG:Nd pulse laser is usually used for cutting and welding. The paper is based by experiments using YAG:Nd pulse laser (KVANT 17-CIS made). Technological modules were assembled for laser beam deviation and for relative sample moving to manual controlled focused laser beam. In experiments was used a personal computer with adequate program for x-y sample moving (stepper system) and correlation with laser pulse. Steel sample (nitralloy steel) was fixed in nitriding chamber in a nitrogen flow. Defocused, laser beam energy and nitrogen pressure were modified. Hardness (HV5), macrostructure and microstructure were used for surface properties investigations.
