    Abstract: 物理氣相沉積法(PVD)在刀具表面披覆上超硬陶瓷在工業上約30年的歷史,最具代表性的為披覆鈦的氮化物,因為TiN、TiCN與TiAlN具有高硬度、低摩擦係數、耐腐蝕性等特性,所以被廣泛運用在刀具上。
    而在本研究中,我們以S50C、420J2兩種材質之市售電纜鉗作為基材,鍍上TiN、TiCN、TiAlN、TiAlCrN/TiAlN雙層膜、TiN/TiAlN/TiAlCN三層膜,觀察鍍膜截面形貌、元素分布、表面粗糙度與摩擦係數等表面性質,以及量測基材硬度、耐磨耗性、計算銳利度指數(BSI)來評估鍍膜對於不同基材切削能力。
      結果顯示基材硬度方面顯示S50C基材發生回火軟化現象,已經影到刀具的耐用性。銳利度方面,鍍膜後的BSI指數皆優於無鍍膜之樣品,其中S50C樣品披覆TiAlCrN/TiAlN雙層膜的樣品BSI指數下降27.93%,420J2則是以披覆TiAlN樣品下降30.71%最好。耐磨耗性部分TiN鍍膜有最低的摩擦係數。
    ;Physical vapor deposition (PVD) super-hard in the industry for about 30 years of history of ceramic coated on the surface of the tool, the most representative of the titanium nitride coated as TiN, TiCN and TiAlN having a high hardness, low friction coefficient, corrosion resistance and other characteristics, it is widely used in the tool.
    In the present study, we used S50C, 420J2 two materials of commercially available cable tongs as a substrate, coated with TiN, TiCN, TiAlN, TiAlCrN / TiAlN bilayer, TiN / TiAlN / TiAlCN three-layer film coating was observed cross section morphology, elemental distribution, the surface properties of the surface roughness and friction coefficient, and a substrate measuring hardness, abrasion resistance, calculated sharpness index (BSI) to evaluate the coated substrate for different cutting ability.
    The results showed that the substrate hardness display S50C base temper softening phenomenon has to shadow tool durability. Sharpness aspect, BSI index after plating are better than the uncoated sample, wherein the sample S50C sample coated TiAlCrN / TiAlN bilayer membrane BSI index fell 27.93%, 420J2 is based on TiAlN coated samples decreased 30.71% best. Abrasion resistance portion TiN coating has the lowest coefficient of friction
