What is not a function of lubricants in mechanical systems?

Lubricants play several critical roles in mechanical systems to ensure smooth operation and longevity of components. One of their primary functions is to reduce friction between moving parts, which minimizes the energy lost due to heat generation and wear. By reducing friction, lubricants also help to prevent wear, extending the life of the machinery.

Cooling is another important function of lubricants. As machinery operates, components generate heat due to friction and other factors, and lubricants help dissipate this heat, maintaining optimal operating temperatures.

However, creating electrical conductivity is not a function of lubricants. Lubricants are generally non-conductive to prevent electrical short circuits and potential damage in electrical systems. Instead, they serve to isolate and protect parts from corrosion and contamination, thereby ensuring proper electrical insulation rather than facilitating conductivity. This distinguishes the function of lubricants from materials designed for electrical purposes, which are intended to conduct electricity.
