11: Failure analysis of tribo-systems

Abstract

The main focus of the present chapter is on the mechanisms responsible for failure in tribo-systems. Several modes of bearings failure are introduced including fatigue, wear, corrosion, and overheating. Fatigue, pitting, fretting, and other modes of gear failure are also addressed. Failure of the cam/follower system, which commonly resulted from cyclic stress at the contact leading to localized deformation or fracture, is highlighted. Fatigue failure at wheel/rail contacts, attributable to the enormous contact and dynamics forces, is discussed. Failure of surface coatings is introduced as a common problem in many tribological components. The final part of this chapter has been devoted to giving ...
