| Abstract: | Titanium and titanium alloys have the low specific gravity, high specific strength, excellent biocompatibility, and good corrosion resistance, showing the great application potential in the aerospace, biomedicine, chemical engineering, shipbuilding, automobile, and other fields. The powder injection molding (PIM) technology used for titanium alloys increases the utilization rate of materials, realizes the large-scale and low-cost preparation of small and medium-sized titanium products with complex shape, and significantly promotes the development of titanium and its alloys. At present, there are few reports about the titanium alloy binder system for powder injection molding, and the development of new type titanium alloy binder system for powder injection molding is in a stagnating state. The research status of the different titanium alloy binder systems for powder injection molding was introduced in this paper, and some improvements for the existing problems were suggested as the reference for researchers. |
