Increase in homogenization of bidisperse mixture of spongy titanium powders and reduction in energy consumption during its preparation in the production of thin permeable elements

In our previous papers it was shown that introduction of spongy titanium powder particles of 10-15% by weight of fine fraction (0.1-0.16 mm) into the charge based on coarse fraction (0.63-1.0 mm) enables to increase the tensile strength of compressed and sintered permeable element samples made from such bidisperse charge under tension from 36-38 MPa to 72-75 MPa. Thus the average sample pore sizes are reduced from 220-240 μm to 143-165 μm. Ensuring its homogeneity in large volumes and thus, if possible, minimizing power consumption for mixing, drying and other possible operations become a problem in the production of permeable elements from such bidisperse charge.
