Industrial Tribology-Friction of Metals and Non-Metals

     

Friction of Metals and Non-Metals

   Friction of Metals

  • The coefficient of friction of a particular materials depends on 3 factors:       1. Mating materials 2. Surface roughness and  3. Operating conditions
  • When the metal surfaces are cleaned in high vacuum and placed in contact, strong adhesion is observed and consequently high friction is observed
