Powder Injection Molding of TiC-10%Ni-10%Mo Cermet
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20 min,最后以3.3 ℃·min-1速率升温至600 ℃,保温30 min;最优烧结工艺是(1 500~1 530) ℃×2 h;所得金属陶瓷的相对致密度高达99%,硬度在95 HRA以上,平均晶粒尺寸小于5 μm.
Abstract
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: heating 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 min 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.
