Abstract

To examine the tribological properties of TiN films and the cutting performance of TiN coated carbide tools, TiN coatings were deposited by using direct current-pulse bias voltage Arc Ion Deposition technique on AISI 1045 steel and YG6 indexable turning tool. The dry tribological behaviors of TiN coating on AISI 1045 steel have been studied in a ball-on-disk tribometer. The dry turning tests of AISI 4119 steel were performed using TiN coated and uncoated carbide tools on the CA6140A lathe. The effects of the two kinds of tools on cutting forces, surface qualities and tool wear have been investigated to assess the performance of TiN coated cemented carbide tools. The results showed that TiN films produce lower friction coefficient than AISI 1045 steel; The main wear mechanisms of TiN coated tool is abrasive wear and accompanied with adhesive, diffusion and oxidation wear.
