Metallized porous ceramic composite material and preparation method thereof
The invention relates to the field of ceramic materials, in particular to a metalized porous ceramic composite material and a preparation method thereof.The preparation method of the metalized porous ceramic composite material comprises the steps that (A) high-purity quartz sand or silicon carbide is subjected to dry ball milling and then sieved, superfine powder is obtained, ferro-nickel alloy powder, boric oxide, a sintering aid, glass powder and a pore forming agent are added, and a mixture is obtained; carrying out low-speed ball milling and fully and uniformly mixing to obtain mixed powder; (B) mixing the mixed powder with a polyvinyl alcohol aqueous solution, and forming by adopting a dry pressing method to obtain a ceramic green body; and (C) drying the ceramic green body in a drying box, preserving heat in a program temperature control box-type furnace, and cooling to room temperature along with the furnace. The dry pressing method adopted by the invention is simple in process, the metal phase is formed in the ceramic by adding the metal alloy powder, the metal phase and the ceramic phase are combined to improve the strength of the ceramic three-dimensional skeleton, the matrix can form metallurgical bonding with the heating layer, the strength is improved, and the oil guide speed of the metalized porous ceramic is accelerated.
本发明涉及陶瓷材料领域，特别涉及一种金属化多孔陶瓷复合材料及其制备方法，一种金属化多孔陶瓷复合材料的制备方法的步骤：(A)将高纯石英砂或碳化硅干法球磨，随后过筛，得到超细粉体，加入镍铁合金粉、氧化硼、助烧剂、玻璃粉和造孔剂，经低速球磨充分混匀后得到混合粉体；(B)将上述混合粉体与聚乙烯醇水溶液混合，采用干压法成型，得到陶瓷生胚；(C)将上述陶瓷生胚在干燥箱中干燥，然后在程序控温箱式炉中保温，随炉冷却至室温。本发明采用的干压法工艺简单，通过加入金属合金粉在陶瓷内部形成金属相，金属相和陶瓷相结合提高陶瓷三维骨架强度，基体能与发热层形成冶金结合，强度提高，金属化的多孔陶瓷的导油速度加快。
