| It is well-known that foot-and-mouth disease (FMD) disinfectant was sprayed on every road near the areas infected by FMD in order to prevent the spread of the disease. Environmental, harmful, and corrosive effects from the spraying of FDM disinfectant are current issues. Most of FMD disinfectant was acidic and many people are concerned about the corrosion of metallic parts of cars, houses and other structures. This work evaluated the effect of FMD disinfectant on the corrosion of carbon steel, aluminium, and galvanized steel. Regardless of the FMD disinfectant, the pHs were acidic and the reduction-oxidation potentials were highly noble. The results of a polarization test confirmed that carbon steel and galvanized steel exhibited anodic dissolution by anodic polarization, but only aluminium exhibited passivity. In an immersion test, the corrosion rate of aluminium was the lowest among three alloys, and with a decreasing dilution ratio of the disinfectants, the corrosion rate of the three alloys linearly increased. Furthermore, an empirical equation to estimate a corrosion rate by various dilution ratios was derived. |
