TURBINE BLADE CAPABLE OF INHIBITING REACTION

摘要

A turbine blade capable of inhibiting a reaction, which has been produced by a method comprising coating the surface of a Ni base superalloy with a reactio n inhibiting agent comprising Co, Cr, Ru or an alloy containing one of these elements as a primary component, prior to aluminum diffusion coating. The turbine blade exhibits enhanced resistance to oxidation as compared to a conventional blade comprising a Ni base superalloy and also can inhibit the generation of a secondary reaction zone.
