Finite Element Analysis Of Surface Hardening Treatments Of Steels For Automotive Powertrain Applications, Filippo Jones

Electronic Theses and Dissertations

Surface hardening is a procedure that is usually performed on steel components, in order to impart in these the strength and surface hardness that are necessary for their correct operation, whilst maintaining a reasonable value of ductility in the overall component.

The latter is usually composed of a sequence of heat treatments: carburizing, quenching and tempering. Each of these have different effects that, if correctly combined, can lead to the desired final mechanical properties in the component.

Carburizing is a process that increases the amount of carbon concentration at the component surface. Quenching is a quick decrease in temperature that …
