INVESTIGATION OF THE PRODUCTION PROCESS OF TWO-LAYER POWDER PERMEABLE MATERIALS BY THE ION-PLASMA SPUTTERING METHOD
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.
