Available in PDF, EPUB and Kindle. Book excerpt: Results of rolling contact fatigue (RCF) tests by balls-on-rod (BOR) and two-roller methods have been compared to those by the balls-on-flat (BOF) method by using three different silicon nitride grades. Two were bearing grade (BG) and one was a general purpose (GP) grade. For a GP material, there was not much difference between the results of BOR and those of BOF, and the observations of a spalled region by BOR suggested similar spalling behavior to BOF. Meanwhile, for BG materials, most tests were terminated without spalling, but grooves, whose likely cause is inferred to be insufficient lubrication, were formed. As for the lifetime in BOR, however, the results for BG materials were much longer than those of the GP, demonstrating that the BOR result is qualitatively consistent with that of BOF, where instead most specimens failed in RCF by spalling or peeling. In the two-roller method, tests of a limited number of specimens were operated at high slip ratios of 10 % during longer cycles under low contact stress, and wear was predominant, suggesting the potential of providing the information on wear behavior rather than RCF. The results suggest that the two-roller method could differentiate the BG materials in terms of wear behavior. Considering these results, both the BOF and the BOR are applicable to distinguish BG and GP materials in terms of fatigue resistance. In particular, the BOF is judged to be more suitable for comparison of the RCF behavior of BG materials, which are commonly tested under higher contact stresses.

Book excerpt: High hardness, low coefficient of thermal expansion and high temperature capability are properties also suited to rolling element materials. Silicon nitride (Si3N4) has been found to have a good combination of properties suitable for these applications. However, much is still not known about rolling contact fatigue (RCF) behavior, which is fundamental information to assess the lifetime of the material. Additionally, there are several test techniques that are employed internationally whose measured RCF performances are often irreconcilable. Due to the lack of such information, some concern for the reliability of ceramic bearings still remains. This report surveys a variety of topics pertaining to RCF. Surface defects (cracks) in Si3N4 and their propagation during RCF are discussed. Five methods to measure RCF are then briefly overviewed. Spalling, delamination, and rolling contact wear are discussed. Lastly, methods to destructively (e.g., C-sphere flexure strength testing) and non-destructively identify potential RCF-limiting flaws in Si3N4 balls are described.
