Abstract
For the production, by hydrostatic pressing, of filters from PTEK, PTES, and PTEM electrolytic titanium powders and a screened 0.63–1.0 mm fraction of the powder forming during the crushing of TG-Tv titanium sponge, the recommended pressure range is 78.5–157 MPa. The mechanical strength of filters from screened TG-Tv powders is, other things being equal, 1.2–4 times higher than that of filters from electrolytic powders. The filtration indicators (coefficients of permeability and filtration) of filters from screened TG-Tv and electrolytic powders are generally virtually identical, but with coarse (0.63–1.0 mm) electrolytic powders they are two to seven times higher than with electrolytic powders.
