The study conducted by the Lehigh University Institute for Metal Forming, funded by Carpenter Technology Corporation, aimed to simplify the selection of coatings for cold heading processes involving stainless steels and high-temperature alloys. Proper lubrication, consisting of coatings and lubricants, is crucial to reduce friction during cold forming, preventing issues like galling and die seizing. Previously, selecting the right coating was challenging due to a lack of objective tests. The researchers developed a two-part testing methodology to evaluate the performance of various coatings under conditions that mimic actual manufacturing processes. The tests, which included wire drawing and trapped wire extrusion, assessed the coefficient of friction and maximum extrusion load, providing valuable data on coating effectiveness. Results indicated that duplex coatings generally outperformed single coatings in severe applications, with specific coatings like Carpenter Technology KnightCote showing significant advantages. The study concluded that both the wire drawing and extrusion processes must be considered when evaluating coatings, and future work will refine testing procedures to further enhance the understanding of coating performance in cold heading applications.
