OXIDATION-RESISTANT, CHROMIUM-OXIDE-FORMING ALLOY

摘要

The invention concerns a chromium-oxide-forming alloy with reactive elements added to the alloy and with reactive elements additionally implanted in the alloy surface or applied thereto. The term "reactive elements" includes chemical elements such as, for example, Y, Ce, Hf and La which have greater affinity for oxygen than does chromium. The material is intended for use at high temperatures since it is more corrosion-resistant than prior art materials. This alloy can in particular be used for bipolar plates for high-temperature fuel cells.
