No matter how well gears are designed and manufactured, gearcorrosion can occur that may easily result in catastrophic failure.Since corrosion is sporadic and a rare event and often difficult toobserve in the root fillet region or in finely pitched gears withnormal visual inspection, it may easily go undetected. This paperpresents the results of an incident that occurred in agearmanufacturing facility several years ago that resulted inpitting corrosion and intergranular attack (IGA). It showed thatsuperfinishing can mitigate the damaging effects of IGA and pittingcorrosion, and suggests that the superfinishing process is asuperior repairmethod for corrosion pitting versus the currentpractice of glass beading.
