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.

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.

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.

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.
