The process of producing powder permeable materials made of spherical bronze powders by tin-phosphorous pressing method has been investigated. A technique for producing experimental samples based on the granulation of powders by a pore-former has been described. The technology is simple to carry out and it does not require complex equipment. Products have a satisfactory set of properties.

The investigation results of the production process of powder permeable materials (PPM) by forming thin permeable layers by means of ion-plasma sputtering method in a vacuum with the use of removable agents have been presented. The method makes it possible to obtain a continuous coating on the surface of the porous substrate. The layer formation on the surface of the porous substrate is provided by the use of the removable agent. After its removal, the layer sputtered on its surface remains an independent unit in the structure of the twolayer permeable material. The coating applied to the substrate has an open porosity.
