Abstract

The invention discloses a metal wear self-repairing composite additive. The metal wear self-repairing composite additive consists of the following raw materials: titanium oxide, silicon dioxide, vulcanized graphene, base oil, anhydrous ethanol, water, a modifying agent and a dispersing agent, wherein the mass ratio of the titanium oxide, the silicon diode and the vulcanized graphene is 3: 3: 1. Bythe characteristic that a resultant in a self-repairing process of the titanium oxide and the silicon dioxide has high carrying ability and in combination with unique anti-wear and anti-attrition properties of graphene and unique effects during physical and chemical reaction in a self-repairing system, the raw materials cooperate with one another, and play roles cooperatively, meanwhile, anti-wear, anti-attrition and repair functions are fulfilled, the process is easy to implement, the suspendability is stable, the effectiveness, reliability and universality are quite good, and the metal wearself-repairing composite additive is suitable for working conditions of high speed, heavy load and high power, and has quite good actual application effects.

Description

technical field [0001] The invention belongs to the technical field of metal wear repair, and in particular relates to a metal wear self-repair composite additive and a preparation method thereof. Background technique [0002] According to the surveys of the United States, the United Kingdom, Japan, and Germany, the economic loss caused by wear and tear failure is huge, accounting for 2% of the total national economic output value of each country. At present, three technologies are mainly used to solve the problem of component wear and failure: anti-wear technology, anti-friction technology and repair technology. Most of the three traditional technical approaches are independent, and their effectiveness, reliability and versatility are also limited. Therefore, countries all over the world are competing to research metal wear self-repairing materials and technologies that can simultaneously reduce friction, wear resistance and repair functions. [0003] With the development...
