Ceramic coating based on prefabricated coating and micro-arc sintering, preparation method and application
The invention belongs to the field of metal surface protection, and particularly relates to a ceramic coating based on a prefabricated coating and micro-arc sintering, a preparation method and application. A preparation method of a ceramic coating based on a prefabricated coating and micro-arc sintering comprises the following steps that S1, ceramic powder, water glass and water are mixed, stirred to be uniform and subjected to ultrasonic defoaming, and slurry is obtained; s2, the surface of a metal matrix is coated with the slurry obtained in the S1, drying and dehydration are carried out, and the metal matrix coated with a prefabricated coating is obtained; s3, the metal coated with the prefabricated coating in the S2 serves as an anode, stainless steel serves as a cathode, the metal and the stainless steel are placed in electrolyte for micro-arc oxidation treatment, the anode is taken out and cleaned after micro-arc oxidation treatment is finished, and a micro-arc oxidation ceramic coating is obtained; according to the preparation method, the sintering process can be completed in a short time, and the energy consumption is reduced. Meanwhile, heat generated in the micro-arc oxidation process is fully utilized, and the energy utilization rate is increased.
本发明属于金属表面防护领域，具体涉及一种基于预制涂层和微弧烧结的陶瓷涂层、制备方法及应用；一种基于预制涂层和微弧烧结的陶瓷涂层的制备方法，包括以下步骤：S1：将陶瓷粉末、水玻璃和水混合，搅拌均匀、超声脱泡得到浆料；S2：将S1得到的浆料在金属基体表面涂覆，进行干燥脱水，得到覆有预制涂层的金属基体；S3：将S2的覆有预制涂层的金属作为阳极，不锈钢作为阴极，置于电解液进行微弧氧化处理，结束后取出阳极清洗，得到微弧氧化陶瓷涂层；本发明的制备方法能在短时间内完成烧结过程，降低了能耗。同时充分利用了微弧氧化过程中产生的热量，提高了能源利用率。
