Composite process, tool block and device for uniformly coating composite brazing filler metal on ceramic surface

Abstract

The invention discloses a compounding process, a tool block and a device for uniformly coating the surface of ceramic with composite brazing filler metal, and particularly relates to a process for uniformly coating the surface of the ceramic with the composite brazing filler metal. On the second aspect, the tool block for uniformly coating the composite brazing filler metal on the ceramic surface is suitable for the process, the tool block is provided with a large groove and a small groove, and the height of the bottom surface of the large groove is higher than that of the bottom surface of the small groove; and on the third aspect, the mounting device for uniformly coating the composite brazing filler metal on the ceramic surface is suitable for the process for uniformly coating the composite brazing filler metal on the ceramic surface, and comprises the tool block, an adjusting bottom plate arranged below the tool block, a balance base arranged below the adjusting bottom plate and a position adjusting mechanism arranged on the balance base, and further comprises a mounting frame, a screen frame is arranged on the inner surface of the mounting frame, and a silk-screen grid is arranged on the screen frame. According to the invention, the composite brazing filler metal for ceramic can be uniformly smeared on the surface of the ceramic, and the thickness of the smeared composite brazing filler metal can be controlled to a certain extent.

Description

technical field [0001] The invention relates to the technical field of brazing processing, in particular to a composite process, a tooling block and a device for uniformly coating composite solder on a ceramic surface. Background technique [0002] At present, there are foils, powders and pastes in the flux. This invention describes the application method of the composite solder (that is, the paste) used for brazing the ceramic surface. The paste benefits from its amount during use. , thickness, shaping and composition ratio are relatively easy to control, but there is no specific method for how to fully consider these factors mentioned before the brazing operation for ceramic surfaces. In the reference materials There is only a statistical description of how much dosage and thickness is mentioned. In various brazing components, the flux is preset at specific points for brazing operations. The traditional coating process is not easy to control the thickness of the coating, a...

[0002] At present, there are foils, powders and pastes in the flux. This invention describes the application method of the composite solder (that is, the paste) used for brazing the ceramic surface. The paste benefits from its amount during use. , thickness, shaping and composition ratio are relatively easy to control, but there is no specific method for how to fully consider these factors mentioned before the brazing operation for ceramic surfaces. In the reference materials There is only a statistical description of how much dosage and thickness is mentioned. In various brazing components, the flux is preset at specific points for brazing operations. The traditional coating process is not easy to control the thickness of the coating, and it is difficult to make the coating layer in the Do not apply solder paste to the side wall of the ceramic under the premise of conforming to the shape and size of the ceramic surface
