Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] Transparent yttrium oxide ceramics are transparent polycrystals with diyttrium trioxide as the main crystal phase. Its light transmission performance is good, and it has a transmittance of about 80% in the far infrared region. Good electrical insulation performance. It is mainly used to make windows, fairings, radomes of infrared missiles, substrates of microwave equipment, insulating brackets, shells of infrared generators, infrared lenses and high-temperature windows, etc.

[0020] Such as figure 1 As sho...

Abstract

The invention discloses a high-temperature metallization technology for yttria ceramic. The active molybdenum-manganese process high-temperature metallization technology is adopted to carry out high-temperature metallization on yttria ceramic and includes the following specific steps of preparation of molybdenum-manganese paste, preparation of a metallization coating, firing of a molybdenum-manganese metallization layer, and electronickelling. In this way, according to the high-temperature metallization technology for yttria ceramic, the active molybdenum-manganese process is adopted to carry out high-temperature metallization on yttria ceramic, the production equipment requirement is lower than that of vacuum magnetron sputtering, and the equipment price is low; meanwhile, as silk screen printing coating and a continuous atmosphere protection tunnel kiln are adopted to carry out metallization, automatic production can be adopted, and large-scale continuous production can be conveniently achieved; due to the technological characteristics of the active molybdenum-manganese process, the bonding strength of a molybdenum layer formed after firing and ceramic is high.

Description

technical field [0001] The invention relates to the field of yttrium oxide ceramic devices, in particular to a preparation process suitable for metallization of yttrium oxide ceramics. Background technique [0002] At present, there is no report on the high-temperature metallization process of yttrium oxide ceramics in China, and no public reports on related patented technologies have been found. The current domestic metallization process for yttrium oxide ceramics is mainly to attach a layer of metal coating layer on the surface of yttrium oxide ceramics by vacuum magnetron sputtering process, and then plate a certain thickness of nickel layer on the surface of the coating layer by electroplating. . In this way, the purpose of metallization of yttrium oxide ceramics is achieved. [0003] Due to the need to use special vacuum magnetron sputtering equipment, the equipment is complex and technically demanding, and it is not conducive to continuous mass production. The bondi...
