In this final Part 6, the Author proposes a new theory of rubber wear connected with rubber friction through abrasion pattern formation generated by stick-slip motion. The kinetic interpretation was introduced to explain the close relationship between the wear rate and the distance of abrasion patterns named the wear-abrasion pattern diagram, which showed that two mechanisms work differently at an initial stage and a final stage of the abrasion pattern formation. After the inspection of the theory of rubber wear given by AG. Thomas theoretically and experimentally, the author proposes a new theory of the rubber wear based on the fracture mechanics treatment, where is shown that the stick-slip motion is the direct driving force to promote the rubber wear, and thus the abrasion pattern of the same length as the period of the stick-slip motion is left on the wear surface of the rubber.
