In the paper,WC-10Co-1TaC adjustable abnormal blade is prepared by powder injection moulding.Scanning electronic microscope,optical
microscope,mechanics machine as well as magnetism test-machine are used to characterize the morphology,appearance,microstructure and mechanical performance respectively.The results show that the cracks and deformations during debinding can be effectively controlled as
solvent debinding and
thermal debinding are combined.The ideal parameters for solvent debinding include the temperature of 40℃,the volume ratio of solvent to sample of 7:1 and the debinding time of 6 h.Correspondingly,the removal of organic binder comes to 50% during solvent debinding.The carbon content can be controlled at a appropriate level after solvent debinding.The specimens are heated from room temperature to 420℃ at the rate of 2 ℃/min,followed by a hold time of 45min.The ultimate bending flexture strength of 2200 MPa(5×5×35),microhardness(HV30)of 1350,coercive force of 10.7 kA/m and cobalt magnetism(Com)of 9.4 can be achieved after sintering at 1 420℃ for 60min in vacuum atmosphere.The properties can completely meet the industrial demands of the parts.
