  • Lubricants
    From engine oils to guns, lubricants (often referred to as lubes) are used in almost every imaginable mechanical system. Contrary to popular belief, lubricants carry out a wide variety of functions apart from friction reduction.
    Reducing surface fatigue
    Lubricants are designed to reduce surface fatigue by keeping moving parts apart, a lubricant acts as a buffer between moving parts. Lubricants can achieve this by various mechanisms, the first is forming a thin physical layer between moving parts. This process is often termed as hydrodynamic lubrication. When the temperature of the moving surface is very high, the lubricant acts as a small cushion to transmit the force of impact and this termed as hydro-elastic lubrication.
