Transition coating suitable for ceramic cold spraying and preparation method and application thereof
The invention belongs to the technical field of ceramic base material surface spraying, and particularly relates to a transition coating suitable for ceramic cold spraying and a preparation method and application thereof. The transition coating suitable for ceramic cold spraying provided by the invention comprises the following components in percentage by weight: 19.5 to 94.5 percent of glaze, 0.1 to 0.5 percent of carboxymethyl cellulose and 5 to 80 percent of metal nickel powder. The preparation method is characterized in that glaze, carboxymethyl cellulose and metal nickel powder in a specific proportion are adopted as raw materials, a transition coating is formed on the surface of the ceramic material through heat treatment, the transition coating has good bonding performance with the surface of the ceramic material, the surface property of the ceramic material is changed, and the service life of the ceramic material is prolonged. The metal coating can be formed on the ceramic surface with the transition coating through cold spraying, the bonding strength of the metal coating and the ceramic material surface is enhanced, the reliability of the metal coating is improved, and a solving thought is provided for solving the problems that the metal coating is difficult to form on the ceramic surface through cold spraying and the reliability of the metal coating is poor.
本发明属于陶瓷基材表面喷涂技术领域，具体涉及一种适用陶瓷冷喷涂的过渡涂层及其制备方法和应用。本发明提供的适用陶瓷冷喷涂的过渡涂层包括19.5～94.5wt％的釉料、0.1～0.5wt％的羧甲基纤维素和5～80wt％的金属镍粉。本发明的关键在于采用特定比例的釉料、羧甲基纤维素和金属镍粉为原料，经过热处理在陶瓷材料表面形成过渡涂层，该过渡涂层不仅与陶瓷材料表面具有良好的结合性能，而且改变了陶瓷材料的表面性质，使得具有过渡涂层的陶瓷表面能够通过冷喷涂形成金属涂层，并增强金属涂层与陶瓷材料表面的结合强度，提升金属涂层的可靠性，为陶瓷表面较难通过冷喷涂形成金属涂层且该金属涂层可靠性较差的问题提供了一个解决的思路。
