Abstract
This paper was studied on the damage behavior of stainless steel (STS 304) for gas boiler with specific resistance. The electrochemical polarization test of STS304 for gas boiler was carried out. And the anodic polarization and damage aspect, such as pitting corrosion, was considered. With being low specific resistance, the passive current density of STS 304 increases, passive region and pitting potential is low. Also, the patting aspect of STS304 In specific resistance
이 논문은 비저항에 따른 가스보일러용 오스테나이트계 스테인리스강(STS304)재의 손상거동에 관해 연구하기 위하여, 비저항에 따른 전기화학적 분극시험을 수행하였다. 그리고 비저항에 따른 가스보일러용 STS304강의 양극분극특성 및 손상거동인 공식양상을 고찰하였다. 비저항이 감소할수록 STS304강의 부동태유지전류밀도는 증가하고 부동태영역은 작아지고 있으며, 관통전위는 낮아지고 있다 또한 비저항이 가장 높은
