Abstract

The invention provides a nano composite material with stable anti-wear and anti-friction functions for a titanium alloy surface. The nano composite material is an oxide particle / multilayer graphene nano composite material prepared by a liquid phase stripping method by taking nano oxide particles serving as an anti-wear component and multilayer graphene serving as an anti-friction component as rawmaterials, and the nano oxide particles are uniformly dispersed on the surface and between layers of graphene sheets. The nano composite material has the following technical effects: 1) when being used on the titanium alloy surface, the nano composite material can simultaneously resist wear and reduce friction, and can thoroughly improve the friction and wear performance of titanium alloys under severe working conditions (such as high load); and 2) compared with the Chinese patent CN 201611018013.7, the nano composite material has the technical progress that the nano composite material can still effectively play the anti-wear and anti-friction functions under the high load, namely, a friction layer has strong stability.

Description

technical field [0001] The invention relates to a nano-composite material with stable anti-wear and anti-friction functions for the surface of titanium alloy, which belongs to the field of material technology. Background technique [0002] The application of titanium alloys began in the 1950s, and has developed rapidly due to a series of excellent properties, and has been widely used in various fields such as aerospace, navigation, automobiles, energy, chemicals, and biomedicine. However, the poor wear resistance and frictional lubricity of titanium alloys limit their engineering applications in the field of friction and wear. [0003] Surface treatment has always been considered to be an effective way to improve the friction and wear properties of titanium alloys, but its high cost, complicated process, and severe working conditions such as high load and high speed often cause cracks and spalling due to stress or thermal stress. criticized. Based on this, the research on ...
