  • Publication number: 20210324201
    Abstract: A coated component may have a consumable coating that protects the component from dust. A coated component may include a silicon containing substrate defining a substrate surface, a barrier coating on the substrate surface, with the barrier coating defining a barrier surface, and a consumable coating on the barrier surface. The consumable coating may include a ceramic oxide that includes a silicate. A component, such as a component of a turbomachine, may be protected from dust by applying a consumable coating on the component.

  • Patent number: 10790731
    Abstract: A method of forming a coating on a component of an electrical machine is presented. The method includes coating a surface of the component with a ceramic material, via an electrophoretic process, to form a first coating. The method further includes contacting the first coating deposited by the electrophoretic process with a polymeric material to form a second coating. The method furthermore includes curing or melting the polymeric material in the second coating to form the coating including the ceramic material dispersed in a polymer matrix.

  • Publication number: 20190170407
    Abstract: A magnetic cooling system is presented. The system includes at least one magnetic assembly, at least one magnetic regenerator including a magnetocaloric material, movably arranged in a closed loop to cyclically pass through the at least one magnetic assembly and a fluid supply device in fluid communication with the at least one magnetic assembly to supply a cooling fluid to the at least one magnetic assembly. A turbine assembly including a magnetic cooling system disposed in a path of an inlet air to a turbine system is also presented.

  • Patent number: 9534817
    Abstract: A heat pump is provided that uses multiple stages of MCMs to cause heat transfer between a heat receiving end and a heat transmitting end. Thermal blocks are placed along the direction of heat transfer at locations in the heat pump that preclude the transfer of heat in a direction from the heat transmitting end towards the heat receiving end. The heat pump can be, for example, part of a refrigeration loop or can be connected directly with the object for which heating or cooling is desired. An appliance incorporating such a heat pump is also provided.

  • Publication number: 20140157793
    Abstract: A novel magneto caloric material (MCM) is provided that can be used in, for example, a regenerator of a heat pump, appliance, air conditioning system, and other heating and/or cooling devices. The MCM is a type of Heusler alloy, has an L21 crystal structural prototype, and can undergo a reversible phase transformation between a low temperature, low magnetization Martensite phase and a high temperature, high magnetization Austenite phase to exhibit an inverse magneto caloric effect upon application of a sufficient magnetic field. A process of annealing of the alloy is also provided that can be used to adjust the temperature at which this phase transformation occurs. The present invention includes the alloy as subjected to such annealing.
