질화규소 볼의 제조 기술 및 성능 최적화에 관한 연구
Oct 08 , 2024
질화규소 세라믹은 비중이 가볍고, 강도가 높으며, 내마모성이 뛰어나고, 전기 절연성과 자기 윤활성이 우수하여 세라믹 베어링 분야에서 특히 고속, 고온, 낮은 토크, 희박 오일 윤활, 질화규소 볼은 롤링 바디 세라믹 베어링으로서 뛰어난 적용 가능성을 보여줍니다. 그러나 질화규소의 강한 공유 결합 특성으로 인해 고상 소결을 통한 치밀화가 어려워 질화규소 세라믹 제조에 어려움이 따릅니다. 본 논문에서는 대기 소결, 열간 압착 소결, 가압 소결을 포함한 질화규소 세라믹의 액상 소결 공정과 이러한 공정이 질화규소 세라믹의 미세 구조 및 기계적 특성에 미치는 영향에 대해 논의합니다. 질화 규소 세라믹은 경량, 고강도, 내마모성, 전기 절연성 및 자기 윤활성과 같은 우수한 특성을 지닌 세라믹 베어링 롤러의 첫 번째 선택...
