Nano-Parctials as corrosion inhibitors for Aluminum alloys in acidic solution at different Temperatures

Synthesis of sulfur nanopartical (SNPs) from mixture theosulphate sodium with Alhagi extra plant. When the change of the color after mixture theosulphate sodium with Alhagi extra plant from yellow to brown indicated the synthesis sulfur nanopartical . Atomic forces microscope (AFM) was used to study the surface topology of the formulated sulfur nanopartical was size 82.39nm. The sulfur nanopartical was used protection aluminum from corrosion in acid media, the study corrosion in different temperature,the inhibition efficiency (%IE) of sulfur nanopartical was high in low temperature, therefore the sulfur nanopartical was active inhibition for aluminum in low temperature in acid media. The values of the thermodynamic parameters at different temperatures for Aluminum in presence sulfur nanopartical are higher than in the absence sulfur nanopartical, also the negative value of ΔH* for corrosion processes in absence and presence sulfur nanopartical reveal the exothermic nature of Aluminum.
