中文摘要：

以TiC、镍和钼粉为原料，采用粉末注射成型工艺制备了TiC-10％Ni-10%Mo金属陶瓷，研究了脱脂方式、脱脂工艺参数及烧结工艺参数对脱脂速率、脱脂率、脱脂坯质量以及陶瓷相对致密度、硬度等的影响，并得到最优工艺。结果表明：二步脱脂工艺优于单纯的热脱脂；优化的脱脂工艺是先在正庚烷中进行溶剂脱脂，然后进行后续热脱脂，以3．5℃·min^-1速率从室温升至60℃，再以2．2℃·min^-1速率升温至300℃并保温20min，最后以3．3℃·min^-1速率升温至600℃，保温30min；最优烧结工艺是（1500-1530）℃×2h；所得金属陶瓷的相对致密度高达99％，硬度在95HRA以上，平均晶粒尺寸小于5μm。

英文摘要：

TiC-10%Ni-10%Mo cermet was fabricated by powder injection molding method with TiC, Ni and Mo powders as starting materials. The influence of debinding and sintering parameters on the debinding rate, binder loss ratio, quality of a brown compact and properties of an as-sintered cermet was evaluated systematically. The results reveal that the proposed debinding process consisted of initial solvent debinding in heptane and a subsequent thermal debinding as following： beating from room temperature to 60℃ at 3.5℃ · min^-1 , then heating to 300 ℃ at 2. 2℃· min^-1 plus a 20 min holding and final heating to 600℃ at 3. 3℃ ·min^-1 plus another 30 rain holding. The optimized sintering process was proposed as （1 500--1 530） ℃ ×2 h, by which the sintered cermet could get relative density over 99%, hardness over 95 HRA and average grain size less than 5 μm.
