ABSTRACT:
The composite of the present invention comprises a layer of ceramic having completely imbedded therein a metal grid, such composite having been made by coating a metal grid with a viscous ceramic slurry and thereafter firing to form the ceramic to a unitary structure. At the temperature to which the composite is fired to form the unitary structure the metal grid is in an expanded condition because of its high coefficient of thermal expansion, and upon cooling the metal grid is put into tension thereby putting the ceramic in compression. The composite is used as a liner for a metal wall which is cast with the liner in situ and is disclosed as having a hollow shape about which the cast wall extends in a manner having particular utility for insulated components of internal combustion engines.
