从几乎完全致密的TiC基金属陶瓷中添加纳米锡粉，在有限比例的单相镍和两相镍钴金属粘结剂的情况下获得的两种刀具，在干切削一种中碳钢(AISI1045)时进行了端面铣削操作。研究了材料的显微组织和力学性能。为了更好地理解热磨损机理，对磨损机理(主要是扩散磨损和氧化磨损)进行了详细的研究和比较。刀具A与刀具B相比，在所采用的切削条件下，刀具A在加工中碳钢时具有较好的抗氧化变形能力，但在相同条件下的冲击破碎性较低。
The two milling tools obtained from nearly full dense TiC-based cermets with TiN nanopowders addition, with limited percentage of monophase nickel and biphase nickel–cobalt metal binders, were tested in face milling operations, in the dry cutting of a medium carbon steel (AISI1045). Microstructure and mechanical properties were studied. Wear mechanisms (mainly diffusion and oxidation) were investigated in detail and compared each other in order to better understand key aspects due to thermal wear mechanisms. Comparing tool A with B, under the adopted cutting conditions, the tool A has a better resistance to oxidation deformation in machining medium carbon steel, but lower impact breakage property on the same conditions.
