| Abstract: |
| Soluble ionic liquid is a kind of organic salts with unique structures and properties that provide high thermal stability, low volatility, and excellent lubricating properties. It also has good thermal and chemical stability, which allows it to maintain its lubricating properties at high temperature and in harsh environments, thereby improving the tribological properties and service life of nickel-based alloys. It can be used as an alternative to greases and conventional lubricants to reduce energy loss and coefficient of friction in metal materials during friction and wear. In the study of tribological properties of nickel-based alloy lubrication additives, the effect of soluble ionic liquids is usually evaluated by tribological experiments. The effect of lubricants on performance indicators such as coefficient of friction, frictional wear, and surface fatigue are tested. Some studies have shown that the use of soluble ionic liquids as lubricant additives can significantly reduce the coefficient of friction and wear of nickel-based alloys. This is because soluble ionic liquids form a protective lubricating film on the metal surface, reducing direct metal-to-metal contact and friction. |
