Scope

Scope: This standard specifies the terms and definitions, classification and naming, technical requirements, testing methods, inspection rules and marking, packaging, transportation, and storage for pre-oxidation of Kovar alloys used in laser-sealed glass-metal joints. This standard only applies to Kovar alloys in laser-sealed glass-metal joint materials. When sealing, the glass is borosilicate glass, and the alloy is an iron-nickel-cobalt alloy with a linear expansion coefficient close to that of borosilicate glass. Here, laser refers to a laser with a wavelength of 800-1100 nm. Main technical content: Pre-oxidation forms a dense metal oxide film on the metal surface, providing a connection transition between the metal, metal oxide, dissolved metal oxide in the glass, and the glass for subsequent high-temperature sealing or laser sealing (welding), ensuring a tight bond between the metal and the glass and ensuring the airtightness and strength of the sealed joint.
