Mechanical and hydraulic characteristics of P/M titanium filters

Conclusions For the production, by hydrostatic pressing, of filters from PTÉK, PTÉS, and PTÉM 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.Translated from Poroskhovaya Metallurgiya, No. 7(235), pp. 34–39, July, 1982.
