Özet
The corrosion effect of exhaust gases expelled from petroleum vehicles on several metals, such as iron, copper, aluminium and galvanized iron sheet was investigated. The investigations were carried out on the number of vehicles and time dependency. For this purpose, a test cell through which the exhaust gases passed directly was developed. The corrosion process on the above mentioned metals was investigated. A parallel test was made with the same elements in an atmosphere free of exhaust gases. The corrosion products formed on the surfaces of material samples were identified as mass loss by atomic absorption spectroscopy (AAS). From the solution formed by exhaust gases pH, lead amount and % compositions of exhaust gases were measured and relative humidity was observed. The surface films of corroded metals were also taken with a metal microscope. According to the experimental results, it was observed that the exhaust gases increased the galvanized iron corrosion rate. This increase occurred most on iron materials, less in galvanized iron ones and the least in copper containing ones.
