PTA법에 의한 스텔라이트 12 합금 육성층의 특성에 미치는 전류의 영향
The Effect of Current on Characteristics of Stellite 12 Alloy Overlayer by PTA Process
초록
Stellite 12 alloy-powders were overlaid on 410 stainless steel valve seat using plasma transferred arc(PTA) process. Variation of the microstructure, hardness, wear and corrosion of overlaid deposit with current change was investigated. The deposit showed hypoeutectic microstructure, which was consisted of primary cobalt dendrite and networked
