Title
A Study on the Ion - Nitriding Characteristics of the High Cr - Mo - V Alloy Steel
김철환Chul Whan Kim, 이상익Sang Ik Lee
Abstract
The characteristics of high Cr-Mo-V alloy steel ion nitrided at 450℃, 500℃ and 550℃ was investigated with two types of specimens; one tempered at 650℃, the other tempered at 650℃ and stress relief annealed at 610℃. The tempered and stress relief annealed sample had slightly greater hardness and bettor wear resistance than the only tempered specimen. The maximum hardness and wear resistance can be obtained in both specimens when ion-nitrided at 500℃. Surface hardness is due to dispersion of chromium nitrides formed on the surface and the hardness decreased by coarsening of chromium nitrides as nitriding time increased. The hardness from the surface into the core increased as the nitrogen diffused inside the matrix and formed the nitriding layer. The relative wear resistance to the slider SKH 9 having greater hardness than the nitrified steel shows better compared with the slider SM 15C having less hardness than the nitrided steel.
