Abstract

This article presents information about methods for evaluating the permeable materials based on metal powders mechanical and filtration properties. It describes methods for determining the permeability coefficient and local permeability coefficient, filtration fineness, and shear strength of powder materials, assessing the sintering quality of composite permeable materials containing fibers, and testing for strength under operating pressure differentials (up to 1 atm). The role of 3D-modeling in improving the efficiency of research is highlighted, enabling the rapid development and manufacture of fixtures for hermetically sealed specimens as their shape and size change.
