本研究採用非平衡磁控濺鍍法，在高速鋼底材鍍上一層鎢鋁薄膜，並探討鍍層於熱處理前後的抗氧化性、磨潤性質、車削與鑽削性質。實驗主要分為三階段：第一階段以改變鋁含量，分析不同鋁含量對鍍層性質的影響；第二階段探討鍍層在不同溫度(500℃與600℃)中，持溫一小時後，對鍍層性質的影響；第三階段選用較佳的鍍層進行鍍層壽命的測試，最後進行車削與鑽削印刷電路板的實驗，以瞭解實際上鍍膜披覆刀具在工業上的應用。
實驗結果得知，鍍層鋁含量愈高，鍍層的硬度則愈低，且附著性也會變差。當鋁含量15 at.%時，鍍層硬度最高，奈米硬度達15.1 GPa(荷重為10mN)，且磨耗性質最佳。經過500℃和600℃持溫一小時的熱處理後，鍍層鋁含量愈高，則氧化深度愈淺，但仍無法改善磨耗深度。
由磨耗壽命結果得知H600-W-Al15鍍層與純鎢鍍層相比，能夠提升9倍的壽命，在由切削結果得知，披覆鋁含量(15 at.%)鍍層得刀具與未鍍膜的刀具相比，車刀刀腹磨耗量降低了59 %，微鑽針刀角磨耗量降低了42 %。

The W-Al thin films were deposited on HSS disc and silicon wafer by unbalanced magnetron sputtering. Before and after heat treatment, the oxidation resistance, tribological properties, turning and drilling performance were investigated. This experiment was divided into three stages. In the first stage, the effect of aluminum content on the mechanical and tribological properties of thin films were analyzed. In the second stage, after one-hour heat treatment with 500℃ and 600℃, the mechanical and tribological properties of these films were investigated. In the third stage, we choose the optimal coating to deposit on disposable inserts and micro-drills to test under practical machining .
The results show that the nano-hardness decreases with increasing aluminum content. The highest hardness and best wear resistance performed by the film which contains 15 at.% aluminum. After heat treatment, although the results show that the oxidation depth decreases with increasing aluminum content , aluminum doping can not improve the wear resistance.
The wear life of Pin-On-Disc shows that H600-W-Al15 can enhance nine times comparing with tungsten film. In turning and micro-drilling tests, the film contains 15 at.% aluminum can reduce the wear rate about 59% on disposable inserts and 42% on micro-drills.
