Abstract
The mechanism of corrosion inhibition of austenitic steels 10X18N10T and 10X17N13M2T in strong acids, as well as the possibility of increasing the anti-corrosive effect of bark extracts by changing the species composition of tree bark, mineral and organic additives have not been sufficiently studied. The aim of the work is a gravimetric and electrochemical study of the effect of temperature and inhibitory compositions based on aqueous extracts of aspen (EKO), spruce (EKE) and pine (EKS) burk on the rate and mechanism of 10X18N10T and 10X17N13M2T steels corrosion in 5% hydrochloric acid. This acid is used with the addition of an inhibitor for washing and chemical cleaning of cooking and heat exchange equipment. New data on the kinetics of acid corrosion of the studied steels are obtained and analyzed, which are necessary to determine the mechanism of inhibition by water-extractive substances of tree bark. It is shown that with the same content of 1 g / l the inhibitory effect of wood bark water-extractive substances on steels acid corrosion increases in a number of EKS <EKE< EKO, with an increase in the concentration of extractive substances to 3,8 g / l and a temperature from 20 to 50 °C, when mixing bark extracts of different types and even stronger when introducing synergists hexamethylenetetramine or potassium iodide into the extracts.
