Problems solved by technology

[0003] Magnesium fluoride infrared wave-transmitting material is a fluorine-containing material. Fluorine-containing materials are typically the most "difficult to stick", with low surface energy and poor wettability. General adhesives cannot fully wet fluorine-containing materials. As a result, it cannot adhere well to fluorine-containing materials, which seriously affects the bonding strength

Abstract

The invention discloses a bonding process for magnesium fluoride infrared hoods. The bonding of magnesium fluoride and quartz ceramic materials can be realized by using a phosphate compound adhesive, which has the advantages of high bonding strength and high temperature resistance. It can be cured at a lower temperature, the process method is efficient and stable, and the cost is low. It is not only suitable for bonding magnesium fluoride materials to quartz ceramics, but also suitable for bonding magnesium fluoride materials to aluminum alloys and other metals.

Description

technical field [0001] The invention belongs to the technical field of wave-transparent ceramics for aerospace, and specifically refers to a bonding process for a magnesium fluoride infrared hood. Background technique [0002] The advantage of radar homing is that it has a long range and has all-weather combat capability, but its anti-interference ability is poor and its resolution to targets is low. Infrared homing has the advantage of high resolution and can complement each other with radar homing. Therefore, countries all over the world are vigorously researching radar / infrared dual-mode guidance technology. Radar hoods are mostly made of high-temperature-resistant wave-transparent quartz ceramics or quartz composite ceramics, infrared hoods are mostly made of magnesium fluoride, spinel and other materials, radar / infrared dual-mode common-aperture composite hoods are made of quartz ceramics or quartz composite ceramics and After the magnesium fluoride material is formed...
