In-situ formation of multiphase air plasma sprayed barrier coatings for turbine components

Patent Subramanian, Ramesh [Oviedo, FL]

A turbine component (10), such as a turbine blade, is provided which is made of a metal alloy (22) and a base, planar-grained thermal barrier layer (28) applied by air plasma spraying on the alloy surface, where a heat resistant ceramic oxide overlay material (32') covers the bottom thermal barrier coating (28), and the overlay material is the reaction product of the precursor ceramic oxide overlay material (32) and the base thermal barrier coating material (28).

Apparatus for determining past-service conditions and remaining life of thermal barrier coatings and components having such coatings

Patent Srivastava, Alok Mani [Niskayuna, NY]; Setlur, Anant Achyut [Niskayuna, NY]; Comanzo, Holly Ann [Niskayuna, NY]; ...

An apparatus for determining past-service conditions and/or remaining useful life of a component of a combustion engine and/or a thermal barrier coating ("TBC") of the component comprises a radiation source that provides the exciting radiation to the TBC to excite a photoluminescent ("PL") material contained therein, a radiation detector for detecting radiation emitted by the PL material, and means for relating a characteristic of an emission spectrum of the PL material to the amount of a crystalline phase in the TBC, thereby inferring the past-service conditions or the remaining useful life of the component or the TBC.

Method and apparatus for measuring on-line failure of turbine thermal barrier coatings

Patent Zombo, Paul J.; Lemieux, Dennis; Diatzikis, Evangelos

A method of remotely monitoring the radiant energy (6) emitted from a turbine component such as a turbine blade (1) having a low-reflective surface coating (3) which may be undergoing potential degradation is used to determine whether erosion, spallation, delamination, or the like, of the coating (3) is occurring.

Turbine repair process, repaired coating, and repaired turbine component

Patent Das, Rupak; Delvaux, John McConnell; Garcia-Crespo, Andres Jose

A turbine repair process, a repaired coating, and a repaired turbine component are disclosed. The turbine repair process includes providing a turbine component having a higher-pressure region and a lower-pressure region, introducing particles into the higher-pressure region, and at least partially repairing an opening between the higher-pressure region and the lower-pressure region with at least one of the particles to form a repaired turbine component. The repaired coating includes a silicon material, a ceramic matrix composite material, and a repaired region having the silicon material deposited on and surrounded by the ceramic matrix composite material. The repaired turbine component amore » « less
