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.

A method of obtaining filter materials from metal powders intended to significantly improve the uniformity of properties along their working surface has been described. The method is easy to perform and is based on granulating the initial powders by the porogen through transferring it into an aqueous solution. It eliminates the segregation of porogen in the bulk of the charge during the implementation of technological operations and enables the automation of the pressing process.
