Abstract

At room temperature, the protective efficacy of the volatile inhibitors (VIC) “IFHAN-A” (A-112, 114 and 118) was studied under atmospheric corrosion of carbon steel St3, brass L62 and copper M2 in the presence of corrosion stimulants (CS) in the air: CO2 ((0.2-0.6) vol. %); H2S ((10- 30) mg /m3); NH3 ((20-60) mg /m3) and 100% relative humidity, which simulates the atmosphere of livestock buildings. In the case of carbon steel in the presence of a binary mixture of CSs: CO2+NH3, CO2+H2S and NH3+H2S, the protective action of the VIC is between 67 and 95%. When corrosion of brass and copper, the protective capacity of IFHAN-112 and IFHAN-118 decreases accordingly to 10 (Cu, IFHAN-112, NH3+H2S) and 13 (brass, IFHAN-118, СО2+H2S) % or 30% (brass, IFHAN-118, NH3+H2S). These VIC stimulate copper corrosion in the presence of a binary mixture (CO2 + H2S). Only in the presence of IFHAN-114, the protective effect does not decrease below 74%.
