Nanoparticle Additives for Improving Lubricant Performance

Abstract

The lubricant is an important industrial product widely used in vehicles and other machines. The main purpose of a lubricant is to reduce friction loss and save energy. However, with the development of the vehicle, the appearance of electrical vehicles, for example, and machines, lubricants need to satisfy more demands. Normally, this was fixed by adding additives. Nanoparticles are one of the best additives because they can efficiently reduce friction loss and provide a more useful function. But nanoparticles may form sedimentation in lubrication, which will increase friction loss and cause damage. Common methods like stirring, ball milling, and chemical methods are used in lab production to keep particles stable in lubricant. All those methods can form relatively stable samples of nano lubricants, but it is still hard for industrial manufacturers because of the technology blank and high cost. Nano lubricant is a potential market and can save more energy in the future.
