Abstract
The process of corrosion st.3 steel in water with thiocarbohydrazide additives had been tested by gravimetric, electrochemical and physics-chemical (UV- and IR-spectroscopy, XR-structure analysis) methods. It was shown that thiocarbohydraz de additives in water decreased the steel corrosion. The corrosion rate decreased time 1.2-7.5 times and protection degree increased to 55-87% depending on testing and of the inhibitor concentration. Mechanism of inhibitor action was proposed.
