| Abstract (in another language): | Interest in metal-ceramic membranes used in filtering equipment, due to their stability in chemically and biologically aggressive environments. Their important characteristic is porosity. This is an aggregate characteristic of the size and number of pores. Changing the parameters of the technological process of creating membranes entails a change in their morphological structure, which in turn changes the porosity. The method of x-ray tomography allows you to control the internal local structure of the membrane without its physical destruction. The visualization of the result of the technological process provides an opportunity to evaluate how the change in a particular parameter of the technological process affects the internal structure of the membrane, and thus optimize the creation process. In addition to this, it is possible to calculate the integral parameters of the structure, such as porosity, specific surface area and pore size distribution. This paper presents the results of a tomographic study of a metal-ceramic membrane obtained by the method of self-propagating high-temperature synthesis. The tomographic reconstruction was performed by back projection with filtering and correction for the effect of “beam tightening”. Additional mathematical processing (bilateral filtering and binarization by the Otsu method for unbalanced classes) was applied to the result of the reconstruction in order to evaluate the porosity of the studied sample, its specific surface and build the pore size distribution. It should be noted that the methods demonstrated and the results obtained allow us to study the effect of synthesis parameters on the quality of the membranes obtained and consider the X-ray tomography method as a candidate for inclusion in the complex of methods for studying membranes. |
