Abstract
A method of making a silver-silicalite coating on a surface of a stainless-steel substrate is provided. The method includes mixing metakaolin with an aqueous solution of NaOH to form a first mixture. The method further includes mixing silica gel and silver nitrate with the first mixture to form a second mixture. Furthermore, the method includes mixing Zeolites Socony Mobil-5 (ZSM-5) with the second mixture to form a third mixture. The method further includes hydrothermally treating the stainless-steel substrate with the third mixture to form the silver-silicalite coating on the surface of the stainless-steel substrate. The hydrothermal treatment is carried out in the absence of an organic template. The stainless-steel substrate coated with the silver-silicalite coating, prepared by the method of the present disclosure, has lower corrosion in comparison to the same stainless-steel substrate without the silver-silicalite coating.
