  • Material selection and conditioning to avoid brittleness caused by nitriding
    Patent number: 6202418
    Abstract: A system for changing the temperature of a working fluid, including amonia, includes a working fluid source and a steel tube. The working fluid source is configured to direct a flow of the working fluid. The working fluid from the source is at a temperature. The steel tube has a treated inner surface layer defining a flow passage. The surface may comprise a mill finish surface, an oxidizing surface and/or a chromized surface. The tube is configured to receive the working fluid from the source and to direct the flow of the received working fluid along a path to change the temperature of the received working fluid.

  • Coatings for turbine components
    Patent number: 6168875
    Abstract: An iridium-niobium alloy bond coat is used under a ceramic thermal barrier coating on turbine blades and vanes to improve the life of the thermal barrier coating. Between the bond coat and the substrate is an underlying protective coating which is either a low pressure plasma sprayed coating such as a NiCoCrAlY alloy or a vapor deposited coating such as tantalum, nickel-tantalum or rhenium. Heat treatment and preoxidation procedures may be used to form the desirable bonds and materials.
