Inve stigation of inhibition effect of ۳-(۲-C hloroph enyl)-۴-(۴ -nitroph enyl)-۱H-۱,۲,۴-triazole-۵(۴H) -thione against copper corr osion in ZnO nanofluid

Nanofl uids are ne w engineer ed material s with great potential to handle th ermal limitation of common thermal fluid (such as water, industrial oil and so on) for using in heat transfer equipments and electrical devices. An im portant overlooked practical feature of nanofluids is how these nanoparticles in th e fluid im pact on the corrosion rates of the metals th at are in contact with the nanofluids. Corrosion i nhibitors are widely used in industry to re duce the corrosi on rate of m etals and alloys incontact with ag gressive. M ost of the corrosion in hibitors are syn thetic che micals, expensive and very haza rdous to environments. Therefore, it is desirable to sourc e for env ironmentally safe inhibitors. There are some reports on the inhibition effects of non-toxic compounds on the co rrosion of m etals.In the present work, the inhibition effect of ۳-(۲-Chloropheny l)-۴-(۴-nitrophenyl)-۱H-۱,۲,۴-triazole-۵(۴H)-thio ne (Cl-ph)as non-toxic compounds on th e copper corrosion in ZnO nanofluid was stu died. ZnO nanopartic les synthesized then potentiodynamic pol arization method and weight-loss measurement we re used to evaluate the inhibition efficiencies . There is not any report of this view that to investi gation of c opper corrosion and in hibition effect of (cl-ph) against coppe r in ZnO n anofluid so far [۱-۵].
