Current failure mechanisms and treatment methods of hot forging tools (dies) - a review

• The hot forging process is the most common method in forming technologies. durability of tools has an effect on total cost up to 30%. Identification current failures mechanisms can assist select suitable treatment method. Treatment methods prolong life cycle tools. This article presents a critical overview failure and applied improve surface integrity die used process. knowledge from this study enables longer mean times between cost-effective processes. In literature, several independent review works have been developed provide conceptual methods. Despite all these efforts, there still no comprehensive improvement mutual frame show research status for preventing present study, presented based theoretical empirical obtained experience authors. paper aims perspective tool failures, including wear (abrasive wear, adhesive oxidation, thermal fatigue cracking), mechanical cracking, plastic deformation, corresponding methods, (nitriding, hybrid procedure, pad welding, beam technology, treatment) coating techniques (CVD, PVD, duplex coating, PACVD, TRD) which turn allows control potentially extend metal
