Alumina and ceramic composite material and preparation method thereof
The invention relates to the technical field of material surface engineering, and especially relates to an alumina and ceramic composite material and a preparation method thereof. The preparation method of the alumina and ceramic composite material comprises the following steps: plating aluminum on the surface of an alumina ceramic matrix to form an aluminum film layer, then carrying out infiltration treatment, and then carrying out Al2O3 phase transformation treatment to change the aluminum film layer into an Al2O3 stable phase layer. The method can effectively inhibit crack propagation of the composite material, can perform hole sealing treatment, is convenient and low in cost, and prolongs the service life of the composite material.
本发明涉及材料表面工程技术领域，具体而言，涉及氧化铝陶瓷复合材料及其制备方法。氧化铝陶瓷复合材料的制备方法包括：在氧化铝陶瓷基体的表面上镀铝形成铝膜层，而后，进行熔渗处理，接着，再进行Al2O3相转变处理使得所述铝膜层变为Al2O3稳定相层。该方法能有效抑制复合材料裂纹扩展，又能进行封孔处理，便捷、低廉提高该复合材料使用寿命。
