Preparation of WC matriz composite and its cutting performance in machining titanium alloys
Titanium and its alloys, in particular the titanium alpha-beta-based alloy Ti6Al4V, are attractive materials due to their unique high strength-weight ratio that is maintained at elevated temperatures and their exceptional corrosion resistance. The major application of titanium has been in the aerospace industry and turbo-engine parts. On the other hand, titanium and its alloys are notorious for their poor thermal properties and are classified as difficult-to-machine materials. Many tools are flaccid in machining titanium alloys. For this reason, a new WC matrix composite tool material was prepared in this paper and the cutting performance was investigated in machining titanium alloys Ti6Al4V. Meanwhile, the influence of cutting speed on wear mode in machining Ti6Al4V alloy is investigated and the wear mechanisms are analyzed. Results shown in the paper that there are many causes for their influences on the tool wear, for example the cutting speed. Not only mechanical and chemical, but also thermo-chemical aspects of wear are important.
