摘要：The corrosion rate of aluminum allo y at deferent concentrations of HCl and NaOH was deduced by chemical methods. It was found that dissolution rate of aluminum alloy depends on the concentration of corrosive med ia. The inhibition efficiency of Cantaloupe juice and seed extracts in 1.0M HCl was higher than that in 1.0M NaOH solutions. In both acidic and basic media, the increase in Cantaloupe extract s resulted in a increase both o f the inhibition efficiency and the degree of surface coverage. Good corrosion inhibitor properties of cantaloupe extracts are due to presence of many organic substances. The adsorption of these organic compounds on the aluminum surface makes a barrier for mass and charge transfers. The adsorption of Cantaloupe juice and seed extract molecules on aluminium metal surface in 10.M HCl obey Langmuir's adsorption isotherm. In case of base media, the adsorption Cantaloupe juice obey Langmuir's isotherm and Temkin iso therm was fit to Cantaloupe seeds.
