Ball on plane rolling tests to evaluate gears contact fatigue

Two groups of specimens were manufactured to obtain microstructural features and mechanical properties similar to gears tooth's surface: a) with shot-peening and b) without shot-peening. Results indicate the occurrence of two failure modes: pitting and spalling. Fatigue life were analyzed using Weibull modelling with maximum likelihood estimation and likelihood ratio tests.
