Title: Deposition of Hard Films on Hot-Working Steel Dies for Aluminum Extrusion

Author: K. Mueller

Description: The author describes a duplex process for improving die performance and the quality of extruded products that consists of applying a combination of a plasma nitiriding (PN) pretreatment and a plasma-assisted chemical vapor deposition (PACVD) or plasma-assisted physical vapor deposition (PAPVD) pretreatment process to a hot-working steel die for aluminum extrusion. The result is to achieve a duplex layer with a higher macro hardness and critical load in comparison with conventional films without plasma nitriding treatment.
