Carburizing of Big Module and Large Diameter Gears - September/October 2002
The article "Carburizing of Big Module and Large Diameter Gears" appeared in the September/October 2002 issue of Gear Technology.
Carburized gears have higher strengths and longer lives compared with induction-hardened or quench-tempered gears. But in big module gears, carburizing heat-treatment becomes time-consuming and expensive and sometimes cannot achieve good hardness due to the big mass-effect. Also, it is not easy to reduce distortion of gears during heat treatment.
