Study on Solvent Debinding Process of Powder Injection Molded Ti(C, N)-based Cermets

摘要

The solvent debinding processes of wax-based binders in powder injection molded Ti(C,N)-based cermets were 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 was studied. It can be found that upwards of 70% paraffin waxes were removed and open pore channels were formed basically when the samples were immersed in heptane for 6 h at 50 ℃.
