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
The present invention relates to a kind of high-performance ceramic surface metallization process.
Background technology
At present in the ceramic metalizing process, just the temperature of viscosity by control metal paste and processing environment improves the quality of metal layer, does not consider that workpiece itself is along with the variation of environment, the weather influence to the metal layer quality.Be prone to pin hole, pile cream, metal layer gage distortion and cracking, flow defectives such as cream, sticking foreign matter all around so be coated with the workpiece that prints off, thereby influence the intensity and the resistance to air loss of last metallized ceramic and metal solder.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, it is pretreated to provide a kind of increase that infrared heating is carried out on the ceramic workpiece surface, can form evenly at ceramic surface, fine and close, smooth high-performance composite ceramics surface metalation production technique.
Technical scheme of the present invention: in the technology of the enterprising row metalization of high-performance ceramic, not only control the viscosity of metal paste and the temperature of processing environment, also set up by the metallized ceramic surface of need is carried out the infrared rays thermal pretreatment, when being coated with bronze printing automatically and belonging to paste, can form evenly, the technology of fine and close, smooth metal layer.By the high-performance ceramic surface that need is coated with seal carry out the infrared heating pre-treatment make the metal cream of certain viscosity can be on its surface fast, launch equably, and at first form thin film fast on the cream surface, thereby make metal layer even, fine and close, smooth, thickness is even, is difficult for foreign matters such as sticking dust, fiber.Concrete technology is as follows: it comprises that to the ceramic workpiece ultrasonic cleaning--------metallization sintering---electroplated and the nickel sintering process to be coated with seal automatically in calcining, it is characterized in that it is that ceramic workpiece is calcined the back and is coated with seal automatically and sets up between preceding ceramic workpiece is carried out the infrared heating pretreatment technology that described high-performance ceramic surface metallization is handled, after being the ceramic workpiece calcining, ceramic workpiece is put into self-propagating infrared heating device carry out infrared heating, its infrared heating pretreatment time is 5-30 minute, temperature in the heating unit is controlled between 40 ℃-100 ℃, the workpiece temperature out is controlled at 60-100 ℃, after carrying out the infrared heating pre-treatment, make its pottery when being coated with bronze printing automatically and belonging to paste, there is the metal cream of certain viscosity can be fast on its surface, flow exhibition equably, and can form thin film fast on the surface, make the metal layer energy evenly, densification, not sticking dust, fiber and various foreign matter; The concrete technology that described high-performance ceramic surface metallization is handled is as follows:
A, ceramic workpiece ultrasonic cleaning: at first the high-performance ceramic workpiece to tight burning carries out ultrasonic cleaning, removes dust and greasy dirt between workpiece surface;
B, calcining: the ceramic workpiece after will cleaning is calcined in pushed bat kiln, and its calcining temperature is 1250-1350 ℃;
C, set up the infrared heating pre-treatment: will calcine good ceramic workpiece and put into self-propagating infrared heating device and carry out infrared heating, be 5-30 minute its heat-up time, heating and temperature control is between 40-100 ℃, and the workpiece temperature out is controlled between 60-100 ℃;
D, be coated with seal automatically: carry out the metal paste at the good workpiece surface of infrared heating pre-treatment and be coated with seal automatically, the metal paste can be fast, flow, launch at workpiece surface equably, forms evenly, fine and close and smooth metal layer;
E, metallization sintering: the workpiece that has a metal layer in high temperature hydrogen furnace in accordance with regulations technology carry out sintering;
F, plating and nickelization: the ceramic workpiece that metallization is sintered is electroplated and is burnt nickel.
By above technology, make can form after ceramic workpiece and the metal solder of band metal layer firmly be connected, resistance to air loss is fine, reliable in quality is stable high-performance composite ceramics.
Gordian technique of the present invention is the performance at paste, rationally control the surface temperature of workpiece, therefore set up the infrared heating pretreatment technology, make the metal paste suitable in the flowability of workpiece surface, guarantee the metal paste can be fast, flow, launch at workpiece surface equably, and form thin film fast on cream surface, and prevent of the adhesion of foreign matters such as dust, fiber at the cream face, make also that metal layer is even, fine and close, smooth, thickness does not evenly ftracture again.
In sum, technical thinking uniqueness of the present invention, processing ease, control is simple, adopts above-mentioned technology, can form even, fine and close, smooth, thickness even metal layer.The metallized ceramic of producing can form with metal solder firmly be connected, resistance to air loss is fine, reliable in quality is stable high-performance composite ceramics spare, quality product qualification rate height reduces the cost depletions of precious metal greatly, obviously enhances productivity.
