High-performance ceramic surface metallization process

Abstract

The invention relates to a high-performance ceramic surface metallization processing technique comprising ultrasonic cleaning, calcining, infrared heating, automatic coating and printing, metalized agglutination, and galvanization and nickel agglutination. The invention is a technique that carries infrared pre-heating treatment on the ceramic surface to be metalized, automatically coats and prints the metal ointment to form an evenly dense flat metallization layer. The invention belongs to one of the techniques for improving the surface function of the high-performance compound ceramics. The metal ceramics which is produced with the technique can be welded with metal to form the high-performance compound ceramic ware which is featured by firm connection, good airproof and reliable quality and is widely applied in the fields of vacuum electronic devices, spaceflight, aviation, broadcast TV, communication, metallurgy, medicine, high energy physics, etc. The technique is easily operated and controlled, and the product has high good yield, thereby greatly reducing the loss cost of the noble metal and significantly improving the production efficiency.

Description

technical field [0001] The invention relates to a ceramic surface metallization treatment process. Background technique [0002] In the current ceramic metallization process, the quality of the metallization layer is only improved by controlling the viscosity of the metal paste and the temperature of the processing environment, without considering the impact of the workpiece itself on the quality of the metallization layer due to changes in the environment and weather. Therefore, the printed workpiece is prone to defects such as pinholes, paste accumulation, uneven thickness and cracking of the metallization layer, paste flow around, and foreign matter sticking, which will affect the strength and airtightness of the final metallized ceramic and metal welding. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, to provide a method of increasing the infrared heating pretreatment on the surface of ceramic workpieces,...
