The effect of alloyed nickel on the short-term high temperature oxidation behaviour of Co–Re–Cr-based alloys
Source abstract
Abstract
Abstract The effect of Ni on the oxidation behaviour of the alloy Co–17Re–23Cr (at.%) is studied. The results show that the alloying of 15 at.% Ni improves the alloy oxidation resistance significantly by promoting the formation of a protective Cr 2 O 3 layer. This effect can be attributed at least partially to the enhancement of Cr diffusion by Ni in the metallic Co–Re–Cr–Ni matrix. Moreover, the formation of relatively slow growing Co(Ni)O solid–solution in the transient stage supports the lateral growth of Cr 2 O 3 nuclei and thus accelerates the establishment of the compact chromia layer.
