What are Nanolubricants?
Nanolubricants are advanced lubricants that incorporate nanoparticles to enhance performance characteristics such as friction reduction, wear resistance, and thermal stability. These lubricants are part of the broader field of
nanotechnology, which deals with materials and devices on a nanoscale, typically less than 100 nanometers in size.
How do Nanolubricants Work?
Nanolubricants work by leveraging the unique properties of
nanoparticles. When added to a base lubricant, these nanoparticles can form a protective layer on surfaces, fill in microscopic asperities, and improve load-carrying capacity. This results in reduced friction and wear, leading to more efficient and longer-lasting machinery.
