101 Method for making ceramic-metal structures US32062173 1973-01-02 US3870776A 1975-03-11 MCMAHON JOHN F
A method for manufacturing metalized ceramic packages, bases and components. A moving belt of plastic film serves as a foundation upon which desired metal patterns and green ceramic patterns can be silk-screened, cast or sprayed in sequence. A secondary ceramic layer, usually thicker, may be applied to serve ultimately as a base layer by casting, doctor blading or other suitable method. After drying, the composite metal and green ceramic structure may be machined, punched or otherwise formed either before or after the plastic film is stripped away. The green ceramic may then be fired in a kiln in a so-called cofiring process to bond the metal to the ceramic as it becomes vitrified.

Methods and apparatus are provided for converting a base material such as paper, wood or concrete to a plastic composite material in which the steps of pressure impregnation of the base material with a monomer and polymerization of the monomer after impregnation by irradiation is accomplished in a single container.

The methods described include placing a first canister containing composite material impregnated with a liquid monomer within radiation receiving proximity to the radiation source, irradiating through walls of the canister the impregnated material in the canister by an amount sufficient to effect partial polymerization of the monomer without raising the temperature to a disadvantageous level, and after partial polymerization of the monomer in the first canister, placing a second canister containing the material impregnated with a liquid monomer between the first canister and the radiation source whereby substantially only radiation passing through the second canister effects complete polymerization of the monomer in the first canister without further materially raising the temperature of the composite material therein.

THE GLAZED FIRED BODY IS QUENCHED IN A QUENCHING MEDIUM AT AN AVERAGE SURFACE COOLING RATE TO AT LEAST 10* C./SEC., AND AT A RATE BELOW THAT WHICH WILL CAUSE THERMAL SHOCK FROM THE FIRING TEMPERATURE TO A TEMPERATURE BELOW THE GLAZE SOFTENING TEMPERATURE FOR FIRST CAUSING MORE RAPID COOLING OF THE EXTERIOR OF THE BODY THAN THE INTERIOR FOR CAUSING PLASTIC FLOW IN THE INTERIOR OF THE BODY AND PRODUCING POSITIVE COMPRESSIVE STRESSES IN THE EXTERIOR OF THE BODY, AND THEN PASSING THE BODY SOFTENING TEMPERATES, FOR CAUSING THE GLAZE TO BE PLACED UNDER A POSI-

TIVE COMPRESSIVE STRESS RESULTING FROM THE DIFFERENCE BETWEEN THE PRODUCT OF THE BODY EXPANSION COEFFICIENT AND THE TMEPERATURE CHANGE OF THE BODY BELOW THE BODY SOFTENING TEMPERATURE AND THE GLAZE EXPANSION COEFFIEICNT AND THE TEMPERATURE CHANGE OF THE GLAZE BELOW THE GLAZE SOFTENING TEMPERATURE. BY THIS METHOD THE BENDING STRENGTH OF THE BODY IS INCREASED AS COMPARED WITH AN UNGLAZED AND UNFIRED BODY OF THE SAME CERAMIC.

A METHOD OF COATING WITH PYROLYTIC CARBON TO PROVIDE A COATED ARTICLE HAVING HIGH STRENGTH CHARACTERISTICS. DEPOSITION OF PYROLYTIC CARBON IS EFFECTED ON AN ARTICLE FROM A CARBONACEOUS ATMOSPHERE AT A PRESELECTED TEMPERATURE UNDER CONDITIONS THAT RESULT IN FORMATION OF CARBON HAVING A PRESELECTED COEFFICIENT OF THERMAL EXPANSION WHICH IS LESS THAN THAT OF THE ARTICLE. DURING COOLING OF THE COATED ARTICLE TO AMBIENT TEMPERATURE, THE DIFFERENCE BETWEEN THE COEFFICIENTS OF THERMAL EXPANSION OF THE ARTICLE AND THE PYROLYTIC CARBON CAUSES THE PYTOLYTIC CARBON COATING TO BE PLACED UNDER, SUBSTANTIAL COMPRESSIVE TANGENTIAL STRESS. DEPOSITION IS USUALLY CARRIED OUT AT A TEMPERATURE OF ABOUT 1500*C. OR BELOW TO DEPOSIT FAIRLY DENSE ISOTROPIC OR LAMINAR CARBON.
