ABSTRACT:
Engine components are thermally insulated with composite layers for improved engine efficiency. A metallic insulation layer is affixed to the metallic substrate of each component, and a layer of heat and corrosion resistant metal overlies and is bonded to the insulation layer. One preferred embodiment incorporates a preformed sheet layer of stainless steel sintered to a layer of metallic insulation attached to the component body substrate. An alternate embodiment incorporates a plasma-sprayed stainless steel layer over the insulation layer. A preferred process for making the engine component includes casting the component body in a mold containing a preformed insulation composite formed of a layer of stainless steel sheet sintered to a layer of metallic insulation.
