粉末冶金钝铬和铬合金材料

Powder Metallurgical Pure Chrome and Chromic Alloy

本文叙述了难熔金属铬的高纯金属加工材料和新型铬基合金材料的新进展。采用纯度为3N5的电解纯铬粉为原料,用粉末冶金工艺制成的高纯铬材,在多种高技术领域得到重视和应用。新型铬合金(Ducrolloy)在燃料电池联结体材料的应用中表现出优异的综合性能。

This article describes new progress in high-pure metal working material with refractory metall chrome and novel Cr - base alloy materials. The electrolytic pure chrome powder of 3N5 purity was used as raw materials. The high pure chrom materials made by powder metallurgy technique were put much value on and have found widely application in many high scienfific and technologic areas, The novel chrome alloy (Ducrolloy) exhibits good combination property in application of connection materials for fuel cell.
