為增進不鏽鋼基材抗腐蝕之特性，本研究以溶膠-凝膠法製備TiO2/SiO2複合溶膠，以旋轉塗佈法分別被覆於304不鏽鋼基材表面後再行熱處理獲致。本研究除了以XRD、GDOS、SEM、EDX分析 TiO2/SiO2複合膜之特性，並以恆電位儀評估（3.5wt% 鹽水中）TiO2/SiO2複合膜對304不鏽鋼耐蝕性之影響。結果發現：XRD分析中，所製備的TiO2-SiO2被覆膜為非結晶結構，隨者處理溫度越高，溫度500度時，其TiO2結晶性會越來越明顯。Ti-O-Si的鍵結的存在，有抑制Cr2O3和Fe2O3的產生，不鏽鋼在產生Cr2O3和Fe2O3氧化物其強度會明顯的減弱，而在經由被覆的基材TiO2-SiO2的鍵結存在可使不鏽鋼基材強度不會明顯的減弱達到保護金屬基材的目的。

Preparing with sol – gel system TiO2/SiO2 films. Get films with in order to rotate coating law cover heat treatment obtain and then behind the surface on 304 stainless steel sill separately
To analyze the characteristic of the film that TiO2/SiO2 with XRD , GDOS , SEM , EDX influence on 304 stainless steel corrosion resistance of film that assess (in the 3.5wt% salt solution ) TiO2/SiO2 and compound with the permanent electric potential . Found finally: XRD in analysing, TiO2-SiO2 film has crystallization structure , in 500 ℃, TiO2 its crystallization can be more and more obvious. Existence that key form of Ti-O-Si, is it suppress Cr2O3 and production of Fe2O3 , stainless steel produce Cr2O3 and Fe2O3 oxide will obvious subsiding, it can make TiO2-SiO2 that cover stainless steel obvious subsiding and achieving and protecting the metal .
