| Abstract: | The catalytic debinding is a new trend of the development direction of debinding techniques of metal injection molding (MIM) due to its inherent advantages. The catalytic debinding of a novel type binder for MIM was studieded in this paper. The results show that the novel catalytic debinding type binder can be quickly removed by catalytic decomposition using HNO 3 gas as the catalyst, and debound part has good shape retention and no obvious defects. It has shown that the debinding time, debinding temperature and composition of feedstock have obvious effect on the debinding efficiency. The weight loss increases with increasing debinding time, debinding temperature, and the polymer blend. |
