چکیده
|
Corrosion in drinking water distribution systems can be caused by several factors,including the type of materials used,the age of the piping and fittings,the stagnation time of the water and the water quality in the system,including its ph. the aim of this work is to study the effect of inhibiting the 5-amino-1,3,4-thiadiazole-2-thiol (att) on the corrosion of ductile iron in a solution simulating the ground. this study was prepared using electrochemical methods. the results show that the att is a good inhibitor in this aggressive environment. the results obtained from the different corrosion assessment techniques are in good agreement. the effect of immersion time,temperature,ph and alkalinity of environment were also studied and the results were discussed. © 2017,university of mohammed premier oujda morocco.
