Duplex treatment

Duplex treatment = Plasma nitriding + PVD coating in one process

The combination of a thermochemical plasma nitriding process with the following deposition of an eifeler PVD coating in an non-interrupted system process we call duplex treatment.

The surface hardness of the tool material is definitively increased, which contributes considerably to the increase in performance of the PVD coating.

Therefore we developed a nitriding process, suitable for this procedure and applied it on an Alpha 900 coating system, where it is performed before the coating process. Basically all coating- and nitriding-capable steel materials are suited for this process.

Tools are an application emphasis for which this procedure currently is selected regularly and successfully for the forming of high-strength sheet materials. VARIANTIC or TiCN is often utilized in this manner.

Combinations with other coatings are also possible. For consultation in concrete applications, our executive consultants are available to you at all times.
