Specimens were anodized in TSA bath then sealed in boiling water bath. Anodizing was performed with potential variations of 11, 13, 15, 17, 19, and 21 volt (V). Corrosion resistance test was carried out by 96 hours salt spray test and potentiodynamic polarization. Coating weight was determined by gravimetric method and coating thickness was determined by metallographic method. Salt spray test results showed that anodizing potential did not affect corrosion resistance. Corrosion potential has the same value with pitting potential for all specimens. Corrosion potential increases with increasing anodizing potential from 11 V until 19 V and then decreases at 21 V anodizing potential. Corrosion current was not affected by anodizing potential. Coating weight and coating thickness increases with increasing anodizing potential.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]2024-T3,Anodizing potential,Corrosion potentials,Corrosion resistance tests,Gravimetric methods,Metallographic method,Potential variations,Tartaric-sulphuric[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Al 2024-T3 alloy,Anodizing,Tartaric-sulphuric[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is supported by PT[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1204/1/012039[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
