A rust converter based on plant components for restoration work.

The main drawback of products based on ferrous metals is their low corrosion resistance in moist conditions. Secondary methods of corrosion protection include methods aimed at stopping the corrosion process and binding the corrosion products to stable compounds where the metal corrosion process has already begun. The paper is concerned with investigating the transformation of steel corrosion products into stable products in the presence of phenolic compounds of plant origin that are economically efficient and environmentally safe inhibitors. The results of the investigation confirm the effectiveness of using hydrolyzable tannins as rust converter, in particular those containing a sufficiently high concentration of gallic acid.
