Abstract: An insulated exhaust port liner of a cylinder head assembly for fluidly connecting to an internal combustion engine of a motor vehicle includes a sealing layer. The sealing layer has a first surface defining a passage for fluidly connecting to the internal combustion engine and receiving exhaust gas. The sealing layer further includes a second surface opposite to the first surface. The liner further includes a thermal barrier layer coated onto the second surface of the sealing layer. The thermal barrier layer is a porous non-woven material for supporting the sealing layer on the cylinder head and reducing a transfer of heat from the sealing layer to the cylinder head.

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.

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.
