摘要

Electroplated Ni-Re film was fabricated as diffusion barrier between NiCoCrAlY coating and orthhombic-Ti2AlNb alloy. The plated Ni-Re film was intact, continuously grown and well-bonded with orthhombic-Ti2AlNb alloy. The oxidation and inter-diffusion behavior of coatings with and without diffusion barrier were both investigated in isothermal and cyclic oxidation tests at 800 degrees C. The results indicated that substantial inter-diffusion and rapid oxidation occurred in the coating without diffusion barrier; while deferred inter-diffusion and improved oxidation resistance were observed, and were attributed to the Ni-Re diffusion barrier.
