Optimization of conditions for the formation of functional coatings based on carboxymethylcellulose with chromium

Abstract

The possibility of increasing the strength and improving the functional properties of coatings based on biopolymers by adding metal powders is considered. An approach has been proposed that makes it possible to form composites based on carboxymethylcellulose with specified mechanical properties. The procedure for adjusting the process of formation and increasing the strength of a protective coating based on carboxymethylcellulose with chromium powder is shown. For the numerical calculation of the composition and temperature conditions for the manufacture of composite materials, a software module developed in the Microsoft Visual Studio environment was used. The calculation makes it possible to determine the combination of components of the coating composition that provides the highest mechanical strength for a given value of the relative deformation of the biocomposite. An example of calculation is given for a protective coating based on carboxymethylcellulose with chromium powder. The calculation results were confirmed experimentally. Using the proposed approach makes it possible to increase the mechanical strength of coatings by 40% and improve the adhesive strength to 1 point.
