The process of steel st.3 corrosion in water with additives of tiosemicarbazide has been tested by gravimetrical, electrochemical and physic-chemical (UV- and IR spectroscopy, X-Ray data, atomic absorp- tive spectroscopy) methods. It was shown that addition of tiosemicarbazide in water effectively protected steel against corrosion. The corrosion rate was 2.2–5.7 times slower and degree of protection increased up to 55.0–82.6 %.
