METHOD OF MANUFACTURING SOLDERED METAL-GLASS COMPOUND

摘要

FIELD: composite materials. SUBSTANCE: method is designed for manufacturing cylinders and other electrovacuum products. Preheating is effected after assemblage. Simultaneously, glass part is heated from hot metal part to temperature exceeding soldering temperature. Preheated parts are cooled in protective gas flow until red glow disappears. In a specific case with molybdenum alloy, high-frequency current preheating temperature is 1300 C, and heating for soldering 1200 C. EFFECT: reduced number of bubbles in solder glass and improved reliability of products. 2 cl, 2 dwg
