Wear of metal-working tools ion plated with titanium nitride

Abstract

AbstractThe tribological properties of ion-plated titanium nitride coatings have been studied in pin-on-disc, dry sand +rubber wheel, and bending-under-tension friction tests. These results are compared with the performance of tools having these coatings in industrial metal-working processes. The coatings were found to increase the life of the tools by two to ten times compared with uncoated tools with the same cutting parameters. The increase in life in the metal-forming processes studied was even longer.
