  • Multiwavelength pyrometry systems
    Patent number: 7633066
    Abstract: A thermal measurement system includes a number of detectors configured to receive radiation within respective wavelength ranges. The system also includes a mirror configured to selectively direct the radiation from an object to each of the detectors. The system further includes an actuator mechanically coupled to the mirror and configured to rotate the mirror through a number of angles. The system also includes an optical and probe subsystem disposed between the object and the mirror to focus the radiation on to the mirror.
    Type: Grant
    Filed: May 22, 2006
    Date of Patent: December 15, 2009
    Assignee: General Electric Company
    Inventors: William Joseph Antel, Jr., Nirm Velumylum Nirmalan, Jason Randolph Allen, Jeffrey Lawrence Williams

  • Article having an improved platinum-aluminum-hafnium protective coating
    Patent number: 6933062
    Abstract: An article protected by a protective coating has a substrate and a protective coating having an outer layer deposited upon the substrate surface and a diffusion zone formed by interdiffusion of the outer layer and the substrate. The protective coating includes platinum, aluminum, no more than about 2 weight percent hafnium, and substantially no silicon. The outer layer is substantially a single phase.

  • Thermal barrier coating resistant to deposits and coating method therefor
    Patent number: 6627323
    Abstract: A protective coating system and method for protecting a thermal barrier coating from CMAS infiltration. The coating system comprises inner and outer alumina layers and a platinum-group metal layer therebetween. The outer alumina layer is intended as a sacrificial layer that reacts with molten CMAS, forming a compound with a melting temperature significantly higher than CMAS. As a result, the reaction product of the outer alumina layer and CMAS resolidifies before it can infiltrate the TBC. The platinum-group metal layer is believed to serve as a barrier to infiltration of CMAS into the TBC, while the inner alumina layer appears to enhance the ability of the platinum-group metal layer to prevent CMAS infiltration.
