| dc.description.abstract | The aim of this work was to study the effect of Gabraun`s water on corrosion of low carbon steel compared with the water from Zweala, Ubari and Sebha. The corrosion tests were carried out in this study. The test solutions used in this study were Gabraun, Zweala, Ubari and Sebha water samples. From the results, it was found that the weights of the specimens immersed in Gabraun`s water were increased, this is because of the formation of scales on the surfaces of the specimen, that was expected to be the result of high pH (10.04), high alkalinity (620) and high TDS. While the weights of the specimens immersed in Zweala Ubari and Sebha water were decreased. From the results of the average of corrosion rates, it was found that the average of the corrosion rate of the specimens immersed in sebha`s water is less than that immersed in the Ubari and Zweala water respectively. Also it was observed that during and after the specimen immersion in Gabraun’s water, the color of the specimens seems to be the same as before the immersion, this is also because of the formation of scales that protect them. The color of the specimens immersed in the other types of water were changed to red brown color. It was assumed that the scale formation can be started at TDS between 58000mg/L and 64000mg/L and also at pH between 9 and 9.5. In addition, the Langelier Saturation Index (LSI) indicator results, give an indication that Gabraun water sample is not a corrosive media (scale formation can occur), while the other types of water samples used in this study are a corrosive media and are compatible with the test results of Gabraun water sample and an average of corrosion rates of other types of water samples. Morever, the potential pH diagram (Pourbaix diagram) for iron exposed to water, give an indication that Gabraun water sample is not a corrosive media, whereas the other types of water samples used in this study are a corrosive media | ar |
