Application of fluorite structure high-entropy ceramic material with excellent wear resistance
The invention relates to an application of a fluorite structure high-entropy ceramic material with excellent wear resistance, which is characterized in that under the atmospheric condition of room temperature, the friction coefficient of the high-entropy ceramic material after friction with a friction pair is 0.25-0.55, and the wear rate is 7.8 * 10 <-8 > mm < 3 >/N.m-5.8 * 10 <-5 > mm < 3 >/N.m. The fluorite-structure high-entropy ceramic prepared by the method disclosed by the invention is high in density, high in hardness and adjustable in component space, so that the fluorite-structure high-entropy ceramic shows relatively high practicability and value, the preparation process is simple and feasible, large-scale production is easy to realize, excellent tribological properties are obtained, and the fluorite-structure high-entropy ceramic is suitable for industrial production. And the development demand of functionalization of the novel high-entropy oxide ceramic material is realized in a real sense.
