Abstract

An 8 wt.% Y₂O₃-ZrO₂/NiCrCoAlY graded coating was fabricated on a TC4 (Ti-6Al-4V) surface by air plasma spraying. Microscopic analysis showed that the ZrO₂/NiCrCoAlY graded coating exhibits a stepwise distribution in composition from metallic bond layer to ceramic top layer, consisting of t′-ZrO₂ phase and supersaturated Ni-based solid solution phase, and displays tight coherence with the TC4 substrate. In addition to mechanical combination, chemicometallurgical reaction combination occurs at some locations and small amounts of NiTi₂ and TiAl₃ phases at the coating-substrate interface develop during spraying.
