Publication Access status: Open Access , Boridische Oberflächen für die UmformungThis study investigates boride surface modifications for forming tools and their applicability from hot forging to bending processes. Gas boriding produces extremely hard boride layers (> 2,000 HV) on tools and high-temperature materials at temperatures above 750 °C. Industrial trials demonstrate significantly reduced wear, doubled tool life, and low coefficients of friction and adhesion against aluminum, copper, and titanium alloys; however, they require adapted process control and post-treatment. Quinary Ti-Si-B-C-N coatings, deposited via PECVD and frequently used as a duplex system with plasma nitriding, achieve superhardness up to 40 GPa, high oxidation resistance, and excellent anti-adhesion even on complex geometries. For bending tools, the combination of both approaches enables application-specific optimization between maximum wear protection, local load-bearing capacity, and economic constraints.Source Type:InProceedings3 9 - Some of the metrics are blocked by yourconsent settings
Publication Access status: Open Access , Datengestützte Umformtechnik: Künstliche Intelligenz zwischen Prozesswissen, Regelung und ProduktionsrealitätWith the 7th Biegeforum, the Chair of Forming Technology at the University of Siegen once again offers researchers the opportunity to present their topics and findings to a specialist audience from industry and academia. This conference volume brings together current research findings and innovative developments in forming technology, highlighting the broad scope of the research field. The Biegeforum thus underscores its role as a key platform for exchange between research and industry — a role it has fulfilled since its first edition in 2011.Source Type:Conference ProceedingsSeries:Forschungsberichte des Lehrstuhls für Umformtechnik3 8
