考察了镍合金基体表面处理对ZSM‐5分子筛膜原位生长及其结合强度的影响，采用纳米压入法测量了ZSM‐5分子筛膜的力学特性，采用热冲击法和拉伸法评价了分子筛膜与基体之间的结合强度。结果表明， ZSM‐5分子筛膜的硬度和弹性模量分别为5.6 GPa和50.6 GPa；基体经高温氧化（950℃）后，原位生长的ZSM‐5分子筛晶体数量减少，分子筛膜的抗热冲击能力提高，界面结合强度降低；基体经盐酸或硝酸处理后，原位生长的ZSM‐5分子筛晶体数量与酸溶液浓度有关，分子筛膜与基体之间的结合强度增大。
攷察瞭鎳閤金基體錶麵處理對ZSM‐5分子篩膜原位生長及其結閤彊度的影響，採用納米壓入法測量瞭ZSM‐5分子篩膜的力學特性，採用熱遲擊法和拉伸法評價瞭分子篩膜與基體之間的結閤彊度。結果錶明， ZSM‐5分子篩膜的硬度和彈性模量分彆為5.6 GPa和50.6 GPa；基體經高溫氧化（950℃）後，原位生長的ZSM‐5分子篩晶體數量減少，分子篩膜的抗熱遲擊能力提高，界麵結閤彊度降低；基體經鹽痠或硝痠處理後，原位生長的ZSM‐5分子篩晶體數量與痠溶液濃度有關，分子篩膜與基體之間的結閤彊度增大。

Influence of surface modification of nickel alloy substrate was studied on in‐situ growth and adhesion strength of ZSM‐5 films .The mechanical properties of ZSM‐5 film were measured by using nano‐indentation test , and the interfacial adhesion strength between zeolite film and substrate was evaluated by using thermal shock test and pull‐off test .The hardness and elastic modulus of ZSM‐5 film were 5.6 GPa and 50.6 GPa , respectively .The oxidation of substrate at 950℃ reduced the number of ZSM‐5 zeolite crystals grow n on the substrate , w hich led to the enhancement of the capability against thermal shock and the weakening of the adhesion strength of ZSM‐5 film .For substrates treated in HCl or HNO3 solution ,the number of ZSM‐5 crystals grown on the substrate depended on the solution concentration and the adhesion strength between zeolite film and substrate w as improved .
