Study on CrC-WC Composite Powders Synthesized by Carbothermal Reduction Method AITranslate
Abstract AITranslate
Cr3C2-30 WC composite powders were prepared by carbothermal reduction method at 1 400 ℃ for 1 h.The phase composition and microstructure of the composite powders were characterized by XRD and SEM,and then the Cr3C2-based cermets were prepared with self-made Cr3C2-10 WC composite powders.The results show that the phase transition during synthesis reaction of Cr3C2-30 WC composite powders is mainly WO3 → WO2.9 → WO2.72 →W(W2C),Cr2O3 → Cr7C3 → Cr3C2 and W solution into Cr3C2 to form(Cr,W) C solid solution.With the carbothermal reduction temperature increases,the grain size of compo-site powders increases,and about 3~5 μm small particles agglomerate and melt to form 10~20 μm large particles at 1 400 ℃.Cr3C2-10 WC composite powders can significantly inhibit growth of the hard phase in traditional Cr3C2-20 Ni cermets.The bending strength of cermets increases from 850 N/mm2 to 1 240 N/mm2,with an increase of 45.9%.At the same time,the HV30 hardness increases from 930 MPa to 1 030 MPa,with an increase of about 10.8%.
