摘 要：Chloride ions interact with aluminium in marine atmosphere to form corrosion *** to this corrosion reaction occurs on their surface,aluminium is oxidized into Al3+.The corrosion reaction accelerates deterioration in metal and it produces galvanic,pitting,stress,crevice,intergranular *** ions decrease internal and external strength of aluminium *** is a very important metal so used in different appliances for ***,water,air transports,housing,railways and other *** and electrospray techniques used to check the corrosion of aluminium *** nanocoating and electrospray materials applied tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and *** materials formed composite barrier and developed a passive surface for *** barrier reduced the corrosion rate of *** spray and chemical vapour deposition technique used for coating *** corrosion rate of metal was determined by gravimetric *** potential and current density were calculated by *** composite barrier formation was confirmed by activation energy,heat of adsorption,free energy,enthalpy and *** thermal parameters were obtained by Arrhenius equation,Langmuir isotherm and Transition state *** adsorption of tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and MgO electrospray on aluminium surface was depicted by Langmuir,Frundlich and Temkin *** results of surface coverage area and coating efficiency were noticed that both materials were mitigated the corrosion rate of aluminium in chloride ions environment.
