Lubricant Reference - Factors Influencing Lubricant Functions

The main functions of a lubricant are contaminant isolation, heat removal, and friction reduction. The important factors that influence these functions are:

Factors Influencing Lubricant Functions

Contaminant Isolation 1. Detergency — Dispersion
2. Corrosion Prevention
3. Rust Protection
4. Stability — Thermal and Oxidative
Heat Transfer 1. Specific Heat
2. Thermal Conductivity
3. Stability — Thermal and Oxidative
Reduction of Friction
1. Coefficient of Friction
  a. Oiliness or Antiwear
b. Anti-seize
2. Viscosity/Temperature Index
3. Pressure/Viscosity Effect
4. Stability — Thermal and Oxidative

Note that thermal and oxidative stability are necessary to perform all functions.
