用溶胶 凝胶法 (sol gelmethod)在不锈钢表面制备了SiO2 TiO2 ZrO2 系无机氧化膜 (STZ)。用DTA/TG、IR、XRD和SEM等手段研究了涂层制备时由凝胶向玻璃态的转变以及涂层薄膜的显微结构特点 ,考察了涂层对基体的保护效果。试验结果表明 ,在溶胶至凝胶最终转变为无机氧化物的过程中形成了无机网络 ,Si4 +和Zr4 +充当了网络骨架的形成离子。涂层为无定型玻璃态 ,其间混有石英、锐钛矿或金红石等微晶。 SiO2 TiO2 ZrO2 inorganic oxide films (STZ) were prepared on stainless steel by sol-gel method. The DTA / TG, IR, XRD and SEM were used to study the transformation from gel to glass and the microstructure of the coating during the preparation of the coating. The protective effect of the coating on the substrate was also investigated. The experimental results show that an inorganic network is formed during the final sol to gel transition to inorganic oxide, and Si4 + and Zr4 + act as the forming ions of the network framework. The coating is an amorphous glassy state with crystals of quartz, anatase or rutile intermingled.
