Vibrational Molding of Filtering Materials Using Stainless Steel and Saponite Powders

The paper describes the results of vibrational molding and proposes a process for producing a gradient filtering material from stainless steel and saponite powders by vibrational segregation. Methods of theoretical and analytical mechanics, oscillation theory, vibrational mechanics, experimental design theory, and computer simulation were used. The surface and microstructure of the samples were examined and their density across the thickness was determined by metallographic analysis using a Micro Optic MMP-4 microscope with the Smart-Eye software. The structural properties and the concentration of the key mixture component were examined throughout the sample height with the ImageJ2x software package. The vibrational amplitude and frequency inducing gradient segregation were determined. An approach was proposed for producing porous gradient filtering materials using an industrial UVM-60/60 vibrating machine. The C++ Builder environment was applied to develop a second-order mathematical regression model by processing the experimental data obtained from a symmetric rotatable uniform design.
