“…This 3.4%-C iron contains about 1% copper and 0.5% manganese (mass composition [11]) and was previously tested on gears with very good results [7]. Austempering aimed at a balanced ADI, without reaching too high of a mechanical resistance to avoid fragilization.…”

a b s t r a c tAn experimental study to evaluate the power dissipation of gears was performed.Three low-loss gear models were manufactured using standard 201 pressure angle tools. Austempered ductile iron (ADI) and 20MnCr5 carburized steel gears were tested in an FZG gear test machine using mineral, ester and polyalphaolephine (PAO)-based oils.The results compare power dissipation, the influence of different tooth flank geometries, materials and lubricants.This work concludes that conventional power-transmission gears can be replaced by these improved and more efficient low-loss models, which can be produced using common tools and that steel gears can be successfully replaced by austempered ductile iron gears.

“…Austempered ductile iron (ADI) has been used for a wide variety of applications in automotive, rail, and heavy engineering industry because of its excellent mechanical properties such as high strength with good ductility, good wear resistance, and good fatigue properties [1][2][3][4]. Furthermore, the density of ADI is lower than steel.…”

“…The use of austempered ductile iron (ADI) for power-transmission gears is possible since improved alloys and heat treatments were developed [5]. Gears made of Cu-Mn ADI were previously tested, scuffing and pitting tests revealing full operative capacity and performance [6,7].…”
