Ti(C,N)基金属陶瓷注射成形溶剂脱脂工艺研究
Solvent Debinding Process of Ti(C,N) Based Cermet Powder Injection Molding
摘 要
以Ti(C,N)基金属陶瓷粉末为研究对象,采用三组不同配比的蜡基粘结剂,考查了注射成形溶剂脱脂工艺中脱脂温度、脱脂时间、试样厚度及溶剂种类和浓度等参数对坯块脱脂率的影响,对溶剂脱脂过程中脱脂坯尺寸的变化及可溶性组元的最大脱除率等也作了初步的研究.结果表明:采用3#粘结剂的脱脂坯溶剂脱脂缺陷最少,较适合于溶剂脱脂;采用正庚烷对该粘结剂的脱脂坯进行50 ℃溶剂脱脂,经过6 h可脱除70%以上的石蜡,连通孔道基本形成.

Abstract
The solvent debinding process of three different wax-based binders in Ti(C,N) based cermet powder injection molding was studied.Effects of debinding temperature,debinding time,sample thickness,solvent types and solvent concentration on binder removal were investigated.Also,the dimension change of samples during the solvent debinding process and the maximal binder removal of dissoluble component were studied elementarily.The solvent debinding quality of the samples based on 3# binder system was the best,and these samples were more suitable for solvent debinding.More than 70% paraffin waxes were removed and open pore channels were formed basically when the samples based on 3# binder system were immersed in heptane for 6 h at 50 ℃.
