A shorter cycle time of the Nitreg® process carried out predominantly on carbon and low alloy materials.

Its objective is to reliably produce a nitrided case with typically increased WL content and a particular nitrided phase configuration in the WL.

Nitreg®–C is a controlled version of nitrocarburizing. It allows for precise Kn control during the process. The additions of carbon bearing gases to the nitriding atmosphere help to increase the relative content of the epsilon phase.

The advantage of a Kn controlled technology is best evidenced when increased wear and/or corrosion resistance is sought. Such properties of the nitrided case are not only influenced by the thickness and relative phase composition of the WL. They also strongly depend on the relative level of porosity developed in the WL.

The Kn control is essential in producing the desired WL configuration

Example of various porosity levels achieved through Kn control are shown below.

Benefits:

• Increased wear/corrosion resistance on selected alloys

• No distortion

• No brittleness

• Excellent process reliability
