This research studies the preparation bipolar plate metal aluminum coated carbon by spraying methods. By piloting the Numbers graphite F H B HB 2B 3B and 4B. Select the graphite rods Numbers are low resistance. Usher graphite rods Conductive color mix used is binder Spraying coating onto aluminum plate 6061. By Conditions in the coating is percent coated specimen 3,6,9, and 12 Graphite by mass. Volume Substances spraying onto specimen at different coatings. Then study interfacial contacts resistance between corrosion rate of specimen.
The results were number 4B graphite rods low have resistance . aluminum plate 6061 at through the coating spraying percent 9 by mass spraying volume is 50 times have corrosion rate equal 0.34348 mm /yr. and interfacial contacts resistance is 87.67 mΩ*cm2 is appropriate value. When Used in study factors of temperature onto specimen plate in the process of coated spraying. Found temperature of the specimen has very less effect for interfacial contacts resistance. but affects the corrosion rate of specimen. can to resistance corrosion well at high temperatures. Because the temperature at 90 °C have corrosion rate smallest 0.1539 mm / yr. which is a condition appropriate be used for Preparation bipolar plate metal aluminum coated carbon.
