最近의 被覆 超硬合金 切削工具

Abstract

本稿에서는 化學蒸着法(CVD)에 依한 Coating으로 Metal protection方法을 紹介하였다. 被覆 切削工具의 生産活動에 큰 活氣를 불어 넣어준 最近 硏究活動의 進步는 많은 超硬合金 製造會社로 하여금 超硬合金에 Titanium Carbide(TiC), Titanium Nitride(TiN), Titanium Carbonitride[Ti(CN)], Alumina(TiC+Al₂O₃, Double layer), Titanium Ozycarbide[Ti(CO)], Hafnium Carbide(HfC), Hafnium Nitride(HfN)를 얇게 被覆시킨 切削工具를 販賣케 하는데 큰 도움을 주었으며 被覆 超硬製品의 需要는 앞으로 增加할 것이 豫想된다.

In this review the protection of metalsusing coatings produced by Chemical Vapor Deposition(C.V.D) is discussed. Developments that has led to a great resurgence in the activity of manufacturing Coated Cutting tools has been marketing by various companies of cemented carbide tool coated by C.V.D. process with a thin layer of TiN, TiC, Ti(CN), TiC+Al₂O₃, Ti(CO), HfN, HfC.
