Study on the Corrosion-resistant Performance of ZSM-5 Zeolite Film on the Surface of Al2024 Xin Liu1,2, Chao Yang3, Guangwen Xie1, Shijie Zhang1, Kun Cheng1, Baorong Hou1 1 College of Materials Science and Engineering, Qingdao University of Science & Technology, Qingdao, 266042, China 2 Key Laboratory of Marine Environmental Corrosion and Bio-fouling, Institute of Oceanology, Chinese Academy of Sciences, Qingdao, 266071, China 3School of Materials and Metallurgy,Northeastern University,Shenyang,110004,China *Corresponding author, xliu_neu@126.com Keywords: Anticorrosion, ZSM-5, Al2024, electrochemical Performance.
If the effective anticorrosion technology was not applied for Al alloy, the service life of aircraft was decreased to lead important accident because Al and Mg alloy were used as skin materials for modern aircraft[1,2].
It is well known that zeolite is a kind of environment-friendly materials without toxicity.
So the kinds of zeolite membranes would become new environment protection materials as anticorrosion coating for metals.

Secondly, the decentralization of implement science and technology resulted in low carbon target relates to each participant in the life cycle of the architecture, including architects, technology provider, makers of complementary products, professional manufacturers , construction organization and production and transportation of building materials.
The main cooperative factors not only include the traditional architectural design elements, such as the building ontologyones--- site, form, space, material, structure, equipment,but also include the expansion to more natural, energy, environment, landscape,ecological, low carbon science and other interdisciplinary elements.
First and foremost is capable of notably economizing on raw materials, fuel or energy emphasis on doing more work with less resources, natural ventilation and day lighting , the energy-saving design of the fender structure,installing water-saving sprinklers and a waste water filter to water flowers and trees , reusing products or recovering their re-usable materials.
The third is the combination of passive technologies and new materials.
Moreover, passive refrigeration technology based on the Suitable phase change materials for building structure provides the double function of geothermal system.

Meanwhile, there are intensive personnel and materials, concentrated fire load, poor air circulation and lighting conditions.
It is possible to cause great economic loss, even incidents with many deaths or casualties for the occurrence of fires, since the personnel and material evacuation are difficult [2].
