Preparation method of metal ceramic coating
The invention discloses a preparation method of a metal ceramic coating. The method comprises the following steps: polishing the surface of a matrix, cleaning the ceramic matrix, removing oil, airing,and preparing a middle layer slurry; spraying the surface of the ceramic matrix wit the middle layer coating material, and sintering the ceramic matrix surface coated with a transition layer in a central control furnace to obtain a uniform and compact transition layer; preparing a surface layer coating; coating the surface of the ceramic with the surface layer slurry, and sintering the ceramic matrix surface coated with the transition layer in a vacuum furnace to obtain a uniform and compact metal ceramic outer layer. According to the invention, the ceramic matrix is pretreated to improve theadsorption effect of the middle layer slurry on the ceramic and ensure the coating uniformity of the middle layer coating material, and the ceramic sprayed with the middle layer coating material andthe surface layer coating material is sintered by adopting a vacuum sintering method so as to improve the uniformity of the coating, reduce the defects of cavities and cracks on the surface of the ceramic and improve the thermal shock resistance and the high-temperature oxidation resistance of the coating on the surface of the ceramic.
本发明公开一种金属陶瓷涂层的制备方法，包括以下步骤：对基体表面进行打磨处理，对陶瓷基体进行清洗、除油和晾干，制备中间层料浆；对陶瓷基体表面喷涂有中间层涂料，将涂有过渡层的陶瓷基体表面放入中控炉中烧结，得到均匀致密的过渡层；制备表层涂料；对陶瓷表面喷涂表层料浆，将涂有过渡层的陶瓷基体表面放入真空炉中烧结，得到均匀致密的金属陶瓷外层。本发明通过对陶瓷基体进行预处理，以提高中间层料浆对陶瓷的吸附作用，保证中间层涂料涂布的均匀性，并采用真空烧结的方法对喷涂过中间层涂料以及表层涂料的陶瓷进行烧结，提高了涂层的均匀性，降低陶瓷表面出现空洞和裂纹的缺陷，提高了陶瓷表面涂层的抗热震性能以及高温抗氧化性能。
