The Use of Volatile #Inhibitors to Suppress Corrosion of #Metals in the Atmosphere of Livestock Buildings by L E Tsygankov in BJSTR

Abstract

At room temperature, the protective efficacy of the #volatileinhibitors (VIC) “IFHAN-A” (A-112, 114 and 118) was studied under #atmosphericcorrosion of carbon steel St3, brass L62 and copper M2 in the presence of #corrosionstimulants (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 #carbonsteel 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%.
