Study on the Influence of Hydrogen Flow Rate and System Inlet-to-Outlet Gas Flow Rate Ratio on the Properties and Compact Strength of Tungsten Powder AITranslate
Abstract AITranslate
Tungsten powder was prepared from yellow tungsten oxide by stepwise reduction.The effects of hydrogen flow rate and system inlet-to-outlet gas flow rate ratio on the properties and compact strength of tungsten powder were systematically studied.The results show that with the increase of hydrogen flow rate,the particle size of tungsten powder is refined,but the change of its compact strength is small.When the hydrogen flow rate is 250 L/min,the particle size of tungsten powder is 3.30μm,and the compact strength is 4.1 MPa.When the hydrogen flow rate increases to 800 L/min,the particle size of tungsten powder is 2.72μm,and the compact strength is 4.2 MPa.At the same time,the system inlet-to-outlet gas flow rate ratio significantly affects the compact strength of tungsten powder.When the system inlet-to-outlet gas flow rate ratio is 1∶1,the particle size of tungsten powder is 2.76μm and the compact strength is 1.6 MPa.When the system inlet-to-outlet gas flow rate ratio is increased to 1∶0.9,the particle size of tungsten powder rises to 3.06μm and the compact strength is increased to 4.4 MPa.
