Nonmetallic Inclusions and Rolling Contact Fatigue

Source

Rolling contact fatigue tests were carried out on an angular contact ball bearing test rig at a low unit pressure (Po = 260 kp/mm2). The results show a sound “relative correlation” between the rolling contact fatigue and the content of nonmetallic inclusions. The theory and actual knowledge of the mechanism of contact fatigue infer that the effect of nonmetallic inclusions is influenced by other material properties, material stressing, and residual stress built up from rolling contact. Hence, a definite correlation between nonmetallic inclusions and the rolling contact fatigue cannot be existent. Nevertheless, it seems to be feasible to develop a simple technique for evaluating the nonmetallic inclusions based on the relative correlation.
