Abstract

The paper describes the vibrational molding results 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, theoretical oscillation and vibrational mechanics, experiment planning theory, and computer simulation are used. Surface, microstructure, and thickness measurements were performed by metallographic analysis using a Micro Optic MMP-4 microscope with the Smart-eye software. The structural properties of the samples and the concentration of the key powder mixture component along the sample height were examined with the ImageJ2x software package. The amplitude and frequency of the vibrating stand that induce gradient separation were determined. An approach is proposed for producing porous gradient filtering materials using UVM-60/60 industrial vibrating equipment. The C++Builder environment was used to develop a second-order regression mathematical model by processing experimental data obtained from a symmetric rotable uniform plan.
