Development of lubricants

Definition

The development of lubricants refers to the process of creating and improving substances that reduce friction between surfaces in relative motion. This advancement has evolved from the use of natural substances like animal fats and vegetable oils to modern synthetic lubricants designed for specific applications, enhancing performance and longevity. Over time, the focus has shifted not only to reducing friction but also to protecting components from wear and tear, corrosion, and thermal degradation.
