Laser hardening and Wear Characteristics of Surfaces hardening steel by YAG LASER
′YAG 레이저에 의한 표면경화강의 레이저 경화와 마멸특성
Abstract
Surface hardening of plain carbon steel (SM45C) by Laser are usually much finer and stronger than those of the base metals. The present study was under taken to investigate the wear resistance and a processing parameters such as, power density, pulse width, defocusing distance, and molten depth for surface modification of plain carbon steel. The wear test was carried out under experimental condition using the wear test device, and in which the annular surfaces of wear test specimens as well as mating specimen of alumina ceramics(
