Surface Hardening of 40Cr10 Steel after Short Time Nitriding in Fluidized Bed
Keywords:
nitriding, thermochemical treatment, steel
Abstract
The paper is based by nitriding in fluidized bed experiments over laboratory plant. Fluidization applications are characterized by high values of mass and heat transfer coefficients. For experiments were used 40Cr10 (Romanian standard) steel specimens. The fluidization and nitriding processes are simultaneously. The results of experiments were investigated by micrograph, hardness and XRD. Micro Vickers investigated micro hardness profiles in section.
