Selecting corrosion-resistant conductive coatings requires low contact resistance, stable surface chemistry, and process-compatible layer formation before long component or stack tests.
Fabricating composition-spread coating libraries, measuring registered positions, and mapping composition, phase, corrosion response, surface change, and contact resistance.
Co-sputtered coating libraries; scanning droplet cell; four-point probe; XRD; surface analysis; uniform follow-up coatings.
Material regions are highlighted when corrosion resistance, conductivity, surface stability, and process fit appear together. Weak regions are excluded before coupon, hardware, stack, or field testing.
