Abstract:To improve oxidation resistance, the granule of refractory metal compound is intermingled with car鄄
bon鄄carbon composite. The change of matrix influences the mechanical property greatly. The cutting temperature in鄄
creased slightly, which was lower than the temperature of common metal obviously. The influence of the cutting tem鄄
perature for the tool life is minimal. However the high hardness of the granule of refractory compound caused the abra鄄
sive increas dramatically, and the decreased of tool life. The dominant wear mechanism was abrasive wear, meanwhile
there was different form of tool wear and tool breakage.
