The invention belongs to the technical field of ceramic coatings, and discloses a superhard ceramic coating method, which comprises the following steps: obtaining a ceramic body to be coated, and carrying out pretreatment operations of primary processing treatment, secondary processing treatment and glazing on the ceramic body to be coated, the preparation method comprises the following steps: preparing a first bottom ceramic coating on the surface of a ceramic body by adopting a plasma spraying method, and drying in the shade at room temperature to form a ceramic coating with a large thermal expansion coefficient and a small elastic modulus; preparing a nano-modified second-layer bottom ceramic coating on the surface of the first-layer bottom ceramic coating by adopting a spraying and sintering method to obtain a superhard ceramic coating with a gradient coating; and sintering the superhard ceramic coating with the gradient coating, naturally cooling the superhard ceramic coating to room temperature, and carrying out pressurized grinding and polishing treatment to obtain the co-sintered superhard ceramic product. The superhard ceramic coating method is simple and easy to implement, raw materials are low in price, and industrial application and popularization are easy.
本发明属于陶瓷涂层技术领域，公开了一种超硬的陶瓷涂层方法，该方法包括：获取待涂层处理的陶瓷坯体，对所述待涂层处理的陶瓷坯体进行第一次加工处理、第二次加工处理以及上光的预处理操作；采用等离子喷涂的方法在陶瓷坯体表面制备第一层底部陶瓷涂层，在室温下阴干后形成具有大的热膨胀系数、小弹性模量的陶瓷涂层；采用喷刷和烧结的方法在第一层底部陶瓷涂层的表面制备纳米改性的第二层底部陶瓷涂层，得到具有梯度涂层的超硬的陶瓷涂层；将所述具有梯度涂层的超硬的陶瓷涂层进行烧结处理，自然冷却至室温后，进行加压磨抛处理，即制得共烧结的超硬的陶瓷制品。本发明的超硬的陶瓷涂层方法简单易行，原料价格低廉，易于工业化应用和推广。
