ABSTRACT
What happens? What is rolling contact fatigue wear? Rolling contact fatigue is material removal/ damage caused by repeated rolling of a solid shape on a contacting solid surface. The usual manifestations include pitting (Figure 5.3), micropitting (Figure 5.4), cracking (Figure 5.5), spalling (Figure 5.6), indentation (Figure 5.7), and brinelling (Figure 5.8). There are many nuances to these manifestations, but these examples present the “flavor” of this form of wear. This chapter will describe the general mechanism of rolling contact fatigue, and then describe in more detail micropitting, pitting, spalling, and slip in rolling contacts.
