Frictional and Wear Behavior of Micro-crystalline and Nano-crystalline Diamond Films
In the present investigation,both micro-crystalline and nano-crystalline diamond (MCD and NCD) films are fabricated,which are characterized by FESEM (Field Emission Scanning Electron Microscopy),surface profilemeter,Raman spectroscopy and Rockwell hardness tester.Moreover,under the dry environment,the frictional behavior of both the films sliding against commonly-used materials in the metal drawing industry is studied on a ball-on-plate rotational frictional tester,including the stainless steel,low-carbon steel,high-carbon steel and copper,demonstrating that the frictional coefficients between NCD films and all these materials are relatively smaller.Furthermore,the wear rates of both the films,which are hardly measured in the ball-on-plate friction tests,are evaluated using a home-made inner-hole line drawing apparatus,with both the diamond films deposited on the inner-hole surfaces and the low-carbon steel wires as the counterparts.Inversely,the NCD films present higher wear rates than the MCD ones,which can be attributed to the deteriorative film purity and adhesion.
