| abstract |
A METHOD FOR SOLID STATE DIFFUSION BONDING OF TWO BODIES OF METAL SUCH AS THE LAMINAS OF A FLUIDIC DEVICE WHEREIN THE SURFACES ARE PREPARED BY REMOVING THE SURFACE OXIDES AND THEN COVERED WITH A SELF-REMOVABLE SUBSTANCE HAVING A LOW SOLUBILTIY OF OXYGEN AND A LOW DIFFUSION RATE OF OXYGEN SUCH AS ALCOHOLS, GLYCERINE, GLYCOLS, POLYBUTENES, ACRYLIC RESINS, LACQUERS AND POLYSTYRENES TO PREVENT OXIDATION OF THE SURFACES. WHILE THE SURFACES ARE STILL COVERED BY THIS OXIDATION-PREVENTING SUBSTANCE, THE BODIES OF METAL ARE ASSEMBLED AND PLACED IN A VACUUM FURNACE FOR BONDING. |
