The nitriding process begins at the surface of the part with the formation of a compound (aka white) layer, which depends to a large extent on the composition of the steel (in particular, the carbon content).

The Doctor has always been fascinated with anything involving case hardening. Gas nitriding is no exception; a seemingly old and well-established technology that changes so little that it begs the question, “What’s new?” Well, as it turns out, quite a bit. Let’s learn more.

The terms sound alike and often cause confusion, but nitrocarburizing and carbonitriding are distinct heat-treating processes.

In order to establish a more effective and economic production system, the goal is to move away from batch-type logistics and toward “one-piece-flow” production.

In order for manufacturers and heat treaters to make an informed decision on what case-hardening equipment to purchase, they must have more than a theoretical knowledge of the processes they may be considering.
