Problems solved by technology

[0005] Traditionally, base oils or anti-wear and anti-friction additives are added to base oils as lubricants. For example, some existing extreme pressure lubricants (such as gear oils, extreme pressure greases) are resistant to Adhesive performance still needs to be improved, and under high temperature conditions, traditional lubricants have a low boiling point and are prone to gasification or deterioration, which cannot meet the conditions of high temperature use

Abstract

The invention discloses a liquid metal lubricant using micro-nano powder as an additive and its preparation and application, in particular to a liquid metal lubricant made of a binary, ternary or quaternary gallium-based liquid metal alloy that is liquid near normal temperature The agent is made by using micro-nano powder with a mass ratio of 0.01%-3% as an additive and a gallium-based liquid metal alloy with a mass ratio of 97%-99.9% for mechanical dispersion and mixing, and is prepared after being fully ground by a three-roller machine. The present invention The liquid metal lubricant has excellent lubricating performance under severe working conditions such as heavy load, high speed and high temperature. At the same time, due to the addition of micro-nano particles, it can fill the wear marks on the metal surface and achieve self-repair of the wear on the surface of the friction pair.

Description

technical field [0001] The invention provides a liquid metal lubricant, which belongs to the technical field of lubrication, in particular to a liquid metal lubricant using micronano powder as an additive and a preparation method thereof. Background technique [0002] Liquid metals refer to metals that are liquid near room temperature. Gallium-based liquid metals have good fluidity, excellent thermal and electrical conductivity at room temperature, low melting point, high boiling point, non-volatile, non-toxic, and have a wide range of application values. . [0003] With the development of industrial technology, equipment continues to develop in the direction of high speed, heavy load, integration, and high precision. The friction and wear caused by the harsh operating conditions of the machine and the high internal temperature have become the biggest constraints to improving the life of the machine. Traditional lubrication is mainly based on two principles: (1) use fluid p...
