Wear rate application, relationship

Figure 8. Relationship between service and specific wear rate and application.

Relationship between WTF as calculated from equibitixial loading to failure for materials with historical clinical application. Data suggests that adhesive-abrasive wear rates are correlated with the innate WTF of the bearing material (Fdidin et al. 2000). 

Application of the very simple relationship shown in Equation (1) requires knowledge of the dependence of stress intensity factor AK and wear rate on external factors, and this is component specific. These relationships are discussed for a railway rail application in Section 3. However, one of the critical determinants of crack growth rate is crack length, while wear is completely independent of crack length. This provides a simple means to investigate the implications of wear-fatigue interaction.
