The paper presents data on strengthening induction heat treatment (IHT) of die tools (punches) and production of wear-resistant Zr-containing coatings on their surfaces. Preliminary results were obtained on the forming limit diagrams (FLD) during drawing (Nakazima’s test) of sheet C45 carbon steel. It was established that punches with Zr-containing coatings after IHT had better characteristics for stretching compared to the uncoated tool steel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
