Porosity % measurement of sponge
WebMar 10, 2024 · Wednesday - March 10, 2024. Porosity is often thought to be a major concern in metal additive manufacturing, but current levels of porosity are not like they were fifteen years ago. Most additive parts we typically see today are at least 99.5% dense, and in many cases, 0.5% porosity does not have an influence on the properties of the part. http://pmdtechnology.com/PMD%20Physics/PMD%20Physics%20-%20Sponges.html

The technique of mercury porosimetry consists essentially in measuring the extent of mercury penetration into an evacuated solid as a function of the applied hydrostatic pressure. As described above, from atmospheric pressure to 200 MPa, a corresponding pore diameter from 15 μm to 7 nm can be covered. WebThe measured l t of the porous P(VDF-HFP) with thicknesses above 300 µm was 6–12 µm in the wavelength range of 420–1100 nm. Later on, Zou et al. developed a 3.5 µm-thick porous PS film with an l t below 1 µm at a wavelength of 500 nm, based on water vapor-induced phase separation. [ 20 ]
