Method for rapidly preparing small-size metal and ceramic composite material
A method for rapidly preparing a small-size metal and ceramic composite material belongs to the technical field of material preparation, and comprises the following specific steps: 1) according to the size of a required sample, a metal block is processed, a metal mold suitable for thermal compression is cut, and the metal mold is composed of a base with a groove in the upper surface and a sealing cover; (2) according to the size of the groove and the size of the sealing cover, the ceramic wafer is cut so that the ceramic wafer can be flatly attached to the groove, the surface roughness Ra of the ceramic wafer is 16-25, and the porosity is 5.24%-6.5%; (3) splicing is carried out, the ceramic chips are placed in the grooves of the base, and the base is covered with a sealing cover; (4) connecting the assembled sample with a thermocouple, putting the sample into a Gleeble 3500 thermal simulation testing machine, and longitudinally carrying out vacuum thermal compression on the sample; and 5) taking out the sample after the sample is cooled. According to the method, the ceramic-metal composite material is prepared by using the mechanical binding force, the ceramic surface does not need to be coated or added with an intermediate layer, the preparation can be completed on a thermal simulation testing machine, and the method has the advantages of simplicity in operation, reliability, low cost and the like.
一种快速制备小尺寸金属与陶瓷复合材料的方法，属于材料制备技术领域，具体步骤为：1)根据所需样品尺寸，对金属块进行加工，切割出一个适用于热压缩的金属模具，所述金属模具由一个上表面设有凹槽的底座和封盖组成；2)根据凹槽和封盖尺寸，对陶瓷片进行切割，使其能够与凹槽平整贴合，陶瓷片表面粗糙度Ra为16‑25，孔隙率在5.24％‑6.5％；3)进行拼装，将陶瓷片放入底座的凹槽中，盖好封盖；4)将拼装好的样品连接热电偶后放入Gleeble 3500热模拟试验机中，对其纵向进行真空热压缩；5)待样品冷却后取出。该方法利用机械结合力制备陶瓷‑金属复合材料，无需对陶瓷表面进行镀层或是添加中间层，在热模拟试验机上便可完成制备，具有操作简单、可靠、成本低等优点。
