Kesan Pemendapan Elektroforesis Gam Arab terhadap Halaju Kakisan pada Aluminium 5052

Abstract: Plat dwikutub adalah salah satu komponen utama sel fuel membran pertukaran proton (PEMFC). Aloi aluminium (Al5052) merupakan salah satu logam yang digunakan sebagai plat dwikutub kerana mempunyai kekonduksian yang tinggi dan ringan. Namun, sistem PEMFC yang berasid (pH3-6) adalah mudah untuk bahan Al5052 mengalami kakisan sehingga dapat mengurangkan prestasi PEMFC. Oleh itu, bagi mengurangkan halaju kakisan yang berlaku, kajian ini menggunakan perencat hijau gam Arab dengan kaedah pemendapan elektroforesis (EP… Show more

“…The EPD process was performed at room temperature with AA5052 as the cathode. The EPD process was conducted for 10, 20, and 30 min with an applied voltage of 20 V. Corrosion rate tests included weight loss analysis of AA5052 coated and uncoated chitosan; these were immersed in 0.5 M H 2 SO 4 for 72, 120, and 168 h at room temperature [19][20][21][22][23].…”

“…Based on Table 4, the corrosion potential values (Ecorr) of metal AA5052 coated with the inhibitor layer were always below the corrosion potential value (Ecorr) of metal AA5052 uncoated with an inhibitor layer; chitosan is a mixed inhibitor with dominant protection in the cathodic area [19][20][21]. A decrease in the value of corrosion potential (Ecorr) at a temperature range of 298 K to 333 K indicated an increase in the anodic reaction, in which the oxidation process took place faster.…”
