SISTEMA DI MATERIALI PER FUNZIONAMENTO AD ALTA TEMPERATURA DI MOTORI A GETTO

摘要

A materials system is provided which is adapted for use in jet engines operable at high temperature and at lower density than possible with nickel base superalloys. A range of niobium base alloys is combined with a range of protective metallic coatings to provide a material system which permits a wide variety of alloy properties and performance characteristics to be combined in structural components of jet engines.
