MECHANISMS OF DRY ADHESION WEAR OF STEELS: INTERPRETATION OF EXPERIMENTAL RESULTS

MECCANISMI DI USURA ADESIVA A SECCO DEGLI ACCIAI: INTERPRETAZIONE DI RISULTATI SPERIMENTALI

Some dry adhesion wear tests were conducted by using a ping-ring type geometry and by coupling various steel grades, making it possible to determine the influence of both operational parameters (load and speed) and metallurgical ones (structure and toughness) on the wear process of steels destined for the manufacture of railroad wheels and rails. The transition phenomenon -- mild wear/severe wear and vice versa -- are explained in terms of structural transformations and superficial oxidation which were observed during microscopic examination and X-ray testing of the wear debris.
