Method of making composite metal and product thereof

Claim 2

A PROCESS FOR METAL CLADDING A METAL BASE, SAID PROCESS INCLUDING POSITIONING A THIN FLEXIBLE LAYER OF CLADDICING METAL ON SAID BASE WITH BRAZING METAL BETWEEN THE MUTUALLY FACING SURFACES OF SAID BASE AND LAYER TO FORM AN ASSEMBLY, ENCLOSING SAID ASSEMBLY IN A SUBSTANTIALLY AIR-TIGHT FIXTURE HAVING A THIN FLEXIBLE METAL DIAPHRAGM WHICH IS SUBSTANTIALLY CO-EXTENSIVE WITH SAID LAYER AND POSITIONED TO PRESS ON THE OUTER SIDE OF SAID LAYER WHEN SAID FIXTURE IS EVACTUATED, EVACTUATING SAID FIXTURE, AND APPLYING BRAZING HEAT TO SAID BRAZING METAL AND SUBSEQUENTLY REMOVING SAID HEAT THEREFROM THROUGH SAID DIAPHRAGM AND SAID LAYER WHILE SAID FIXTURE IS EVACUATED, SAID LAYER AND SAID DIAPHRAGM BEING THIN AND FLEXIBLE ENOUGH UNDER ATMOSPHERIC PRESSURE TO FLEX THROUGHOUT THE ENTIRE EXTENT OF SAID LAYER AND FORCE SAID SURFACES TO CONFORM TO EACH OTHER THROUGHOUT THEIR EXTENTS AND TO PRESS TOGETHER UNDER PRESSURE UNIFORMLY DISTRIBUTED THROUGHOUT ON SAID BRAZING METAL THEREBETWEEN.

Claim 3

A PROCESS FOR METAL CLADDING A METAL BASE, SAID PROCESS INCLUDING POSITIONING A THIN FLEXIBLE LAYER OF CLADDING METAL ON SAID BASE WITH BRAZING METAL BETWEEN THE MUTUALLY FACING SURFACES OF SAID BASE AND LAYER TO FORM AN ASSEMBLY, ENCLOSING SAID ASSEMBLY IN A SUBSTANTIALLY AIR-TIGHT FIXTURE HAVING A THIN FLEXIBLE METAL DIAPHRAGM WHICH IS SUBSTANTIALLY CO-EXTENSIVE WITH SAID LAYER AND POSITIONED TO PRESS ON THE OUTER SIDE OF SAID LAYER WHEN SAID FIXTURE IS EVACUATED, EVACTUATING SAID FIXTURE, AND APPLYING BRAZING HEAT TO SAID BRAZING METAL AND SUBSEQUENTLY REMOVING SAID HEAT THEREFROM THROUGH SAID DIAPHRAGM AND SAID LAYER WHILE SAID FIXTURE IS EVACTUATED, SAID LAYER AND SAID DIAPHRAGM BEING THIN AND FLEXIBLE ENOUGH UNDER ATMOSPHERIC PRESSURE TO FLEX THROUGHOUT THE ENTIRE EXTENT OF SAID LAYER AND FORCE SAID SURFACES TO CONFORM TO EACH OTHER THROUGHOUT THEIR EXTENTS AND TO PRESS TOGETHER UNDER PRESSURE UNIFORMLY DISTRIBUTED THROUGHOUT ON SAID BRAZING METAL THEREBETWEEN, SAID BRAZING METAL BEING POSITIONED BETWEEN SAID SURFACES IN THE FORM OF A UNIFORM DISPERSION OF POWDERED PARTICLES OF SAID BRAZING METAL, SAID PARTICLES BEING ADHESIVELY FASTENED TO ONE OF SAID SURFACES BY A THIN LAYER OF DRY BRAZING FLUX.

Claim 4

A PROCESS FOR METAL CLADDING A METAL BASE, SAID PROCESS INCLUDING POSITIONING A THIN FLEXIBLE LAYER OF CLADDING METAL ON SAID BASE WITH BRAZING METAL BETWEEN THE MUTUALLY FACING SURFACES OF SAID BASE AND LAYER TO FORM AN ASSEMBLY, ENCLOSING SAID ASSEMBLY IN A SUBSTANTIALLY AIR-TIGHT FIXTURE HAVING A THIN FLEXIBLE METAL DIAPHRAGM WHICH IS SUBSTANTIALLY CO-EXTENSIVE WITH SAID LAYER AND POSITIONED TO PRESS ON THE OUTER SIDE OF SAID LAYER WHEN SAID FIXTURE IS EVACUATED, EVACTUATING SAID FIXTURE, AND APPLYING BRAZING HEAT TO SAID BRAZING METAL AND SUBSEQUENTLY REMOVING SAID HEAT THEREFROM THROUGH SAID DIAPHRAGM AND SAID LAYER WHILE SAID FIXTURE IS EVACTUATED, SAID LAYER AND SAID DIAPHRAGM BEING THIN AND FLEXIBLE ENOUGH UNDER ATMOSPHERIC PRESSURE TO FLEX THROUGHOUT THE ENTIRE EXTENT OF SAID LAYER AND FORCE SAID SURFACES TO CONFORM TO EACH OTHER THROUGHOUT THEIR EXTENTS AND TO PRESS TOGETHER UNDER PRESSURE UNIFORMLY DISTRIBUTED THROUGHOUT ON SAID BRAZING METAL THEREBETWEEN, SAID BRAZING METAL BEING POSITIONED BETWEEN SAID SURFACES IN THE FORM OF A UNIFORM DISPERSION OF POWDERED PARTICLES OF SAID BRAZING METAL, SAID PARTICLES BEING ADHESIVELY FASTENED TO ONE OF SAID SURFACES BY A THIN LAYER OF DRY BRAZING FLUX.

Claim 5

CLADMETAL PRODUCED BY THE PROCESS OF CLAIM 6 AND COMPRISING A METAL BASE HAVING A CLADDING LAYER SECURED THERETO BY A BOND IN THE FORM OF A FLUX SLAG WHICH FORMS A HIGH DISPERSED PHASE MINGLED WITH A MATRIX OF BRAZING METAL.
