- Abstract
The efficiency of forging processes is significantly influenced by the tool and scrap costs which in their turn depend on the life time of forging dies. The tools used for hot forging are subject to process-related high mechanical, tribological, chemical and thermal-cyclic loads which usually interact with each other. In comparison to other manufacturing methods, the resulting load spectrum leads to extensive wear and thus to the failure of forging dies after a short tool life. To increase the wear resistance of forging dies, duplex treatments consisting of plasma nitriding and plasma deposition techniques were used to improve the surface properties and hence to increase the die life time. By basic investigation of the wear mechanisms the potentials of newly developed vanadium doped chromium nitride and boron containing titanium nitride coating systems were investigated. Within the presented work it is demonstrated that vanadium-doped chromium nitride layers have a high wear reduction potential for hot forging dies.
