Dry cutting performance of tools deposited with TiSiN–WS2/Ti–WS2 coatings

Abstract
Two kinds of hard lubricant coatings, TiSiN–WS2 (TW) and TiSiN–WS2/Ti–WS2 (TTW), were deposited on cemented carbide tools. Microstructure and mechanical properties were studied. Dry cutting tests on hardened steel were conducted. Results showed that TTW coating had higher adhesive strength than TW and TiSiN coatings. After 2000 m dry cutting, the lubricant layers of TiSiN–WS2 and TTW coated tools were worn out, but the TiSiN layer almost kept intact and still protected substrates. Tools with TTW coating exhibited the best cutting performance with the smallest cutting force, lowest cutting temperature and no Fe adhesion on rake face. While behaviours of TiSiN–WS2 coated tools were similar to that of TiSiN coated tools, especially in high cutting speed. The deposition of WS2/Ti increased lubricant layers wear resistance and played a transition role between TiSiN and WS2 layers. This is much helpful to prolong its lubricant effect and to decrease tool wear.
