AGMA 99FTM5-1999 pdf download

Early stages of micropitting were examined on experimental gears designed for surface fatigue studies by the AGMA Helical Gear Rating Committee. Optical profilometer, SEM and metallographic examinations were conducted on the first prototype gearset tested. The gearset...
