  • The technique of high speed machining is widely studied in machining field. In this study, TiAIN single-layered and TiAIN/TiN double-layered coatings were applied to end-mill by an arc ion plating technique. Their performances were comparatively studied about cutting force, tool wear, tool life and surface roughness of workpiece under high speed cutting conditions. The TiAIN single-layer coated tool showed higher wear-resistance due to its higher hardness, while the TiAIN/TiN double-layer coated tool showed better performance for high metal removal, i.e., high fled per tooth condition due to its higher toughness. The surface roughness of the workpiece was not influenced by the wear amount of coated tools.

  • 아크이온플레이팅법과 스퍼터링법을 이용하여 금형의 보호코팅으로서 CrTiAlSiN 박막을 합성하였다. 연구는 CrTiAlN 피막에 Si이 첨가됨에 따른 농도변화가 피막의 경도 및 내열성에 미치는 영향을 조사하였다. Si 함유량 변화에 따른 특성의 변화에 대해 XRD, TGA, 경도분석, 윤활성의 분석을 통해 조사하였으며, 함성된 피막은 기존 CrN 박막 대비 내열성이 우수하게 향상되었으며 경도의 향상과 낮은 윤활성을 보였다.

  • The Charcteristics of the HCD ion plating system for TiN coating was Investigated. 1-V curvet of the HCD ( hollow cathode discharge ), radiation temperatures of the Ta tube and the Ti pool and the electron density and the temperature of the generated plasma are shown. The preferred orientation and the micro-hardness of coatings performed by HCD process are studied.
