Corrosion behavior of composite Udimet 700 with (5%& 10%) alumina powder superalloys was studied in 1 M HCl using some new organic compounds “4-((4-aminophenyl) diazenyl) benzene-1,2-disulfonic acid (compound I), N-(benzo[d] thiazol-2-yl) -2-cyanoacetamide (compound II) and ethyl (E)-2-cyano-2- (2-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)hydrazono) acetate (compound III)”. Electrochemical studies were carried out, utilizing potentiodynamic polarization, electrochemical impedance spectroscopic and electrochemical frequency modulation methods. Tafel plots demonstrate that the pre...
