  • Publication number: 20230235440
    Abstract: An abradable powder composition is includes a metal component, a lubricant component, and a polymer component. A portion of the metal component is wrapped in the lubricant component to achieve high lubricity and abradability. The abradable powder composition can be used to form an abradable seal coating provided for use in a turbo machinery having a housing and a wheel having multiple blades. The housing houses the wheel which rotates therein. The seal coating is formed on the inner walls of housing adjacent where the wheel blades pass during their rotation. When the wheel is rotated such that, the blades contact the seal coating, it is abraded to form a close fit gap. The abradable seal coating preferably does not produce significant wear of the blade tips or transfer abradable material significantly to the blade tips upon being abraded.

  • Publication number: 20110086177
    Abstract: The invention provides a method for forming a thermal barrier coating having vertical cracks for improved thermal and mechanical stress tolerance. The method can include depositing a first sub-layer on a substrate at a first temperature T1, followed by depositing a second sub-layer on the first sub-layer at a second temperature T2, wherein T2 is less than T1 such that a temperature gradient having a negative heat flux toward the top of the second sub-layer is created, thereby introducing thermal stress in the sub-layers causing vertical cracks to be formed in the sub-layers. The method then involves repeating steps (a) and (b) for n cycles to form the thermal barrier coating comprising the vertical cracks, wherein n is an integer from 1 to 200.

  • Publication number: 20110086163
    Abstract: The present invention provides methods for producing a crack-free abradable coating with enhanced adhesion. The methods include the steps of providing a substrate and applying an abradable material to the substrate, either directly or indirectly via one or more additional layers. A critical coating temperature of the abradable material is determined that ensures that the thermal stress level in the abradable material is lower than the tensile strength of the abradable material. The temperature of the abradable material is held at a constant temperature below the critical coating temperature throughout the step of applying the abradable material to the substrate.

  • Patent number: 7485366
    Abstract: Thick film magnetic/insulating nanocomposite materials, with significantly reduced core loss, and their manufacture are described. The insulator coated magnetic nanocomposite comprises one or more magnetic components, and an insulating component. The magnetic component comprises nanometer scale particles (about 1 to about 100 nanometers) coated by a thin-layered insulating phase. While the intergrain interaction between the immediate neighboring magnetic nanoparticles separated by the insulating phase provides the desired soft magnetic properties, the insulating material provides high resistivity, which reduces eddy current loss.
