據文獻指出非晶質合金具有優良的機械性質、抗蝕性與抗菌性，可應用於醫療器械開發，故本研究選用鋯基與鋯銅基非晶質合金以塊狀與薄膜型式製備非晶質合金手術刀與非晶質合金鍍膜手術刀，藉切削橡皮，計算刀刃與橡皮間各工作階段作用力，以比較商用、非晶質塊材與鍍膜手術刀之銳利度。
鋯基與鋯銅基非晶質合金藉由下吸式銅模鑄造出2mm與3mm厚度之板材，2mm板材將加工製作成濺鍍靶材以直流濺鍍非晶質薄膜至商用手術刀上，3mm板材則將用於製作成非晶質合金手術刀之原材料，再進行切削實驗並計算刀具銳度指標(Blade Sharpness Index, BSI)，以比較各種手術刀具銳度之差異，刀具銳度指標之數值越低其銳度越高。
非晶質合金手術刀經研磨拋光後，先由XRD確認其仍為非晶質合金後，進行銳度實驗，由實驗的結果可知，商業用手術刀之刀具銳度指標為0.335，鋯基非晶質合金手術刀刀具銳度指標為0.26，鋯銅基非晶質合金手術刀為0.252，銳度提升比率方面，鋯基為22.4%，鋯銅基則為24.8%，可知鋯銅基非晶質合金手術刀其刀具銳度指標略優於鋯基，且兩者皆較商用手術刀為佳。
在非晶質合金鍍膜手術刀方面，鋯基與鋯銅基非晶質合金鍍膜手術刀其刀具銳度指標分別為0.249和0.231，銳度提升比率為25.7%與31%，可知非晶質金屬鍍膜手術刀，其銳度皆較未鍍膜之商用手術刀佳，其中鋯銅基鍍膜在銳度提升方面之表現最為優異。
經由實驗可知，不論是非晶質合金手術刀或是非晶質金屬鍍膜手術刀，其銳度皆較商用手術刀為佳。再加上非晶質合金所具有之優異機械性質，抗蝕性與抗菌性，相信是未來手術刀具相當好的選擇。

Amorphous alloys have excellent properties about mechanical properties, corrosion resistance, and antimicrobial ability. This research choose different types scalpel blades – commercial scalpels, scalpels made of amorphous alloy, and scalpels coat with amorphous alloy thin film, and use these scalpel to cut the rubber plate. The composition of the amorphous alloy is about Zr-Cu-Ni-Al-Ni and Zr-Cu-Ag-Al-Si, After the cutting experiment, we calculate the data to compare the blade sharpness of the different scalpels.
At first, the scalpels of metallic glass (MG) were checked by XRD to ensure its amorphous state, and then do the cutting experiment. The results of cutting test revealed that the Blade Sharpness Index (BSI) of 0.260 for the scalpels made of Zr based MG and 0.252 for the scalpels made of Zr-Cu based MG, and 0.335 for the commercial scalpels, respectively. In summary, the sharpness can be improved about 22.4% to 24.8% for the Zr-based and ZrCu-based MG scalpel.
Moreover, the results of cutting test also show that the BSI of 0.249 for the scalpel which coating the Zr based MG thin film by DC pulse magnetron sputtering process, and 0.231 for the Zr-Cu based, and sharpness can be improved about 25.7% and 31%. The scalpels with coating MG thin film are sharper than the commercial scalpels.
The scalpels made of MG and the scalpel blade coats with MG thin film, these scalpels both sharper than the commercial scalpel blades. Due to the excellent properties of the MG, we believe that the MG will be the good choice to make the scalpel blades in the future.
