Nanotechnology is the field of study and application of extremely small things, often at the scale of individual atoms and molecules. In the context of lubrication, it can be used to create lubricants with improved performance characteristics such as reduced friction, enhanced wear resistance and improved stability at high temperatures. One way this is done is through the incorporation of nanoparticles, which can be made from materials such as clear carbon, graphene, and tungsten . These particles have dimensions on the nanoscale, typically ranging from 1 to 100 nanometers. They can improve lubricant performance by filling in surface asperities, forming a protective layer on surfaces and increasing the lubricant’s ability to flow. Another application of nanotechnology in lubrication is the use of nanostructured surfaces, which can be used to create low-friction and wear-resistant coatings on machinery and other mechanical components. Overall, the use of nanotechnology in lubrication has the potential to improve efficiency and lifespan of machinery in a variety of industries including aerospace, military, and high-performance applications. It is important to evaluate the specific requirements of the application and the characteristics of the lubricant to ensure that it is suitable for the intended use.
