RESEARCH INVESTIGATION OF CORROSION-RESISTANT MATERIALS FOR ELECTROCHEMICAL CELLS

Abstract

The diffusion block concept for the rapid preparation of a broad range of alloy systems and for the rapid screening of these alloys for their corrosion resistance in specific environments is verified. Qualitative information on the diffusion-zone characteristics are obtained by visual or optical observations and the chemical composition for areas of high corrosion resistance is determined by electron microprobe analysis. Two diffusion blocks were constructed and tested. The first block contained cobalt, iron, nickel, chromium, molybdenum, and tungsten; the second block contained niobium, tantalum, vanadium, chromium, molybdenum, and tungsten. The preliminary results indicate good corrosion resistance in phosphoric acid for a binary alloy containing molybdenum and nickel.
