摘要

This work employed the PVD process to deposit coatings of single layer TiN, binary layer TiN/TiCN, multilayer TiN\Ti\TiN and sequenced TiN\TiCN\TiN multilayer coatings with variable individual TiN and TiCN layers' thickness on tungsten carbide disks and inserts. Also investigated herein were the fracture mechanisms and the influence of sequence and thickness of these coatings on cylinder-on-disk line contact wear mode and ball-on-disk point contact wear mode through SRV reciprocating wear tests. Actual milling tests were also performed to identify the wear performance. Experimental results indicate that the coating with a total thickness of 7 μm and layer sequence TiN/TiCN/TiN exhibits good wear resistance on SRV wear test and milling test. The thickest multilayer TiN/Ti/TiN coating, although having the highest hardness, has the worst wear resistance for all tests. Notably zero-wear performance was observed for all coating disks under cutting fluid lubricated condition due to the transferred layers formed between the contact interface.
