Abstract

The corrosion behaviour of as-rapidly solidified and heat treated AI 8Ni-2Co alloy ribbons produced using melt spinning technique was  investigated. The decomposition behaviour of the rapidly solidified ribbons  was followed up using x-ray diffraction, differentialscanningcalometry.  microhardness, and metallography. The stable phases which are generally  formed in conventional solidified alloy in the as cast condition, were not  detected in the as-rapidly solidified specimens. Instead, super-saturated  solid solution α-AI was present in addition to fine dispersoids of  A19(CoNi)2. The corrosion behaviour was investigated through  potentiostatic technique in 3.5% NaCL aqueons solution. The corrosion  rate was the lowest in the as-rapidly solidified condition and increased  with increasing the annealing temperature as a result of the formation and  coarsening of the intermetallic Al3Ni.
