The spur gear in question was found to have cracks at most of the spline roots (~80%). The crack surface showed brittle mode of failure. Analysis suggests hydrogen embrittlement as the mechanism of failure. Improper processing appears to be the reason for hydrogen embrittlement. A detailed analysis of the failure has been presented in this report and a few recommendations suggested for preventing the recurrence of similar failure.
