No matter how well gears are designed and manufactured, gear corrosion can occur that may easily result in
catastrophic failure. Since corrosion is sporadic and a rare event and often difficult to observe in the root fillet
region or in finely pitched gears with normal visual inspection, it may easily go undetected. This paper
presentstheresultsofan incidentthatoccurred in agearmanufacturing facilityseveral yearsagothatresulted
in pitting corrosion and intergranular attack (IGA). It showed that superfinishing can mitigate the damaging
effects ofIGAand pitting corrosion, and suggests that the superfinishing process is a superior repair method
for corrosion pitting versus the current practice of glass beading.
