A FACE-CENTERED CUBIC FERROMAGNETIC DAMPING COATING

A method to increase the damping of a substrate using a face-centered cubic ferromagnetic damping coating having high damping loss attributes when a strain amplitude is 500-2000 micro-strain, and/or maximum damping loss attributes that occurs when the strain amplitude is greater than 250 micro-strai...

Beschreibung
Zusammenfassung:	A method to increase the damping of a substrate using a face-centered cubic ferromagnetic damping coating having high damping loss attributes when a strain amplitude is 500-2000 micro-strain, and/or maximum damping loss attributes that occurs when the strain amplitude is greater than 250 micro-strain, and a turbine component having a face-centered cubic ferromagnetic damping coating. L'invention concerne un procédé permettant d'augmenter l'amortissement d'un substrat à l'aide d'un revêtement d'amortissement ferromagnétique cubique à faces centrées comportant des attributs de perte d'amortissement élevée lorsqu'une amplitude de déformation se situe entre 500 et 2 000 microdéformations, et/ou des attributs de perte d'amortissement maximale qui se produisent lorsque l'amplitude de déformation est supérieure à 250 microdéformations, et un composant de turbine ayant un revêtement d'amortissement ferromagnétique cubique à faces centrées.
