二元過渡金屬氮化物薄膜，如鈦(Ti)及氮化鈦(TiN)的良好性能已受到人們廣大關注，且Ti/TiN所形 成的雙層複合膜被預期成為多功能材料，氮化鈦薄膜透過氣體流量比氮氣/(氬氣+氮氣）=10%，並使用 直流式反應磁控濺鍍系統將雙層複合膜沉積在Si wafer和SS316L表面上，本研究透過X光繞射儀(XRD)、 掃描式電子顯微鏡、四點探針、恆電位儀、電化學阻抗譜、薄膜厚度輪廓測量儀等方法研究了添加Ti輔 助附著層對Ti氮化物膜的微觀結構、形貌、電學性能和電化學性能的影響，結果可知Ti / TiN雙層薄膜 微結構比單一的TiN膜層更穩定，且當金屬膜為氮化物膜時，膜的電阻率增加，最後可以觀察到雙層膜 表現出有較好的耐腐蝕性，其SEM形貌顯示更平滑可知具有更密型態的雙層結構有利於耐腐蝕性提升。

In Taiwan, there is a fire accident occurred in the battery storage room of a thermal power plant. After field observation and preliminary investigation, the main failure WPS happened in^lead acid battery-positive terminal, whicli was seriously burned. Due to the use of the battery in the fire burned never encountered before--t is worth to further clarify the failure cause. In this study, background information, macro observation, failure cross section investigation, metallographic observation of failure material, corrosion products analysis were used to investigate the failure cause of the lead acid battery. According to the results of this study, corrosion is the main failure cause, where the other influencing factors including materiaTs defects, electrode oxidation reaction, design of battery-electrode plates and environment temperature. The estimated failure mechanism is proposed, the electrical conducting are^of battery-positive terminal was reduced due to corrosion, which caused electrical resistance increased. After cyclic charge and discharge, the current became too high for the battery, which leaded to a high temperature and caused the battery being bum out
