Abstract

The invention discloses a preparation method of nano ceramic powder with a lubrication function, ceramic slurry is prepared by pressurizing high temperature roll milling, a specific lubricant and a specific defoaming agent are added, and the nano ceramic powder with the lubrication function can be obtained by screw stirring paddle natural cooling, centrifugal spray drying, sieving, heat treatment,screening and other a series of process for optimization. The nano ceramic powder with the lubrication function effect has good wear resistance, small friction, good lubrication, and good applicationprospect.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a preparation method of nanometer ceramic powder with lubricating function. Background technique [0002] High-performance structural ceramics have many excellent properties such as high temperature resistance, wear resistance, corrosion resistance, high strength, and oxidation resistance. They are ideal materials for manufacturing high-temperature lubricating and wear-resistant components. From the perspective of future development, high-temperature structural ceramics are low-density structural materials that can work for a long time above 1000°C and have high strength and corrosion resistance. At present, due to the inherent brittleness of ceramic materials and the decline in mechanical properties of materials caused by tribological design, their wider application in the field of high-temperature lubrication is largely limited. However, the scale of matter after n...
