摘要:
A nickel alloying process includes providing a metal powder containing substantially unalloyed nickel for high inherent thermal conductivity, forming a nickel alloy from the metal powder with addition of additives to form a uniform fine thermo-dynamically stable incoherent precipitate dispersion like carbides, oxides or nitrides, apply mechanical or thermo-chemical reactions to form or maintain a uniform fine dispersion of the incoherent precipitates, removing air and absorbed water from the nickel alloy, and hot extruding the nickel alloy to substantially full density and prescribed dispersion strengthened condition. A net result is a dispersion strengthened high thermal conductivity nickel alloy.
摘要:
An oxidation resistant coating system for a turbine engine component includes a cathodic arc coating applied to a surface of the engine component, a thin APS metallic coating applied to a surface of the cathodic arc coating, and a ceramic top coating applied to a surface of the thin APS metallic coating to improve lifetime of the engine components.
