摘要：

In this paper, Ni-Co coatings on Al foil were prepared by electroplating to obtain Al/Ni-Co composite. Phase transformations and magnetic property of Al/Ni-Co composite heated at 823 K for 80 h were investigated. The results showed that obviously exchanged zone in Al matrix exited and the thickness was about 2.5 mu m. Ni diffused into the Al easilier than Co. beta phase (AlNi and AlCo) and (gamma) phase (Al(Ni, Co) solid solution) of Co-Ni-Al formed during the annealing. The Ms of was decreased significantly when Al diffused into the Ni Co alloy film and formed Ni-Al and Co-Al intermetallic compounds.
