  • Internal combustion engine and method for coating internal combustion engine components
    Patent number: 10190533
    Abstract: An internal combustion engine includes a component configured to be subjected to combustion gasses, the component includes a substrate presenting a surface and a coating applied to the surface of the substrate. The coating includes an insulating layer applied to the surface having a plurality of microspheres and a sealing layer bonded to the insulating layer and seals against the insulating layer.
    Type: Grant
    Filed: August 8, 2016
    Date of Patent: January 29, 2019

  • Ceramic microsphere thermal barrier coating
    Patent number: 10040723
    Abstract: A thermal barrier coating for a component includes an insulating layer applied to a surface of a substrate. The insulating layer comprises a plurality of ceramic microspheres. A sealing layer is bonded to the insulating layer. The sealing layer is non-permeable such that the sealing layer seals against the insulating layer. A method for applying a thermal barrier coating to a surface of a substrate of a component includes providing a plurality of ceramic microspheres and applying the plurality of ceramic microspheres to the surface of the substrate. At least one heat treatment is applied to the plurality of ceramic microspheres on the surface of the component to create an insulating layer on the surface of the substrate.

  • METALLIC MICROSPHERE THERMAL BARRIER COATING
    Publication number: 20180186144
    Abstract: A metallic thermal barrier coating for a component includes an insulating layer having a plurality of metallic microspheres applied to a substrate. A second metallic non-permeable layer is bonded to the insulating layer such that the sealing layer seals against the insulating layer. A method for applying a thermal barrier coating to a component includes placing an insulating layer having a plurality of microspheres to a surface of the substrate of the component. A heat treatment is applied to the insulating layer. A second non-permeable layer is bonded to and seals against the insulating layer.
