✦ Synopsis

This paper is a study on the kinetics ofcorrosion of some types ofcarbon steel: OLC-15,OLC-35, OL-37 and OLC-45 in acid corrosive media: HCI, HCIOs, HC104 and HsPO1, in various experimental conditions. In order to follow the evolution of the corrosion process, we have used a radiochemical method based on the principle of isotopic dilution. The corrosion process, specific for the systems under study, has been quantitatively described by means of a kinetic parameter called "the degree of resistance of metallic sample against the action of the aggressive medium". Out of the experimental data, we have noticed that, at each moment, the degree of resistance of each type of steel under study in theacid corrosive solutions with the same concentration, increases in the series: HC1-z HCIO, < HCIO, < H 3 Pod, whence we have drawn the conclusion that the hvdrochloric acid is a much stronger corrosive medium than the chloric, perchloric and phosphoric acids.
