ABSTRACT:
A composition of matter including a substrate of a metal that is susceptible to corrosion in a high pH alkaline solution, a corrosion-resistant base layer disposed on the surface of the substrate, the base layer having a pure or high silica zeolite having a silicon:aluminum atomic ratio of at least about 100, a middle mixed zeolite layer disposed on the surface of the base layer, and a top hydrophilic layer disposed on the surface of the middle layer, the top layer having a high aluminum zeolite having a silicon:aluminum atomic ratio of less than 5. The middle mixed zeolite layer includes a zeolite having a silicon:aluminum atomic ratio range that is between the silicon:aluminum ratio of the pure or high silica zeolite of the base layer and of the high aluminum zeolite of the top layer.
