Introduction to Electrodeposition (ED) Experimental Laboratory

Outline

(Click each photo to view a high-resolution one.)

• We have a laboratory in Ookayama Campus of Institute of Science Tokyo (Meguro-ku, Tokyo) where we can conduct electrodeposition (ED) experiments.
• A variety of experiments can be conducted: evaluating ED behavior such as throwing power, identifying ED mathematical model parameters that can be used with the ED simulator "EDESFEM", etc..
• As the ED lab is a university facility, people from outside the university can also conduct experiments as they like by re-configuring and adding devices.
• ED paint should be prepared-and-sent by a paint manufacturer or collected-and-sent from an actual ED line. (The lab does not have equipment for making ED paint.)
• Pre-treated plates (test pieces) should be manufactured and sent by test piece companies. (The lab does not have equipment for making test pieces.)
• If you would like to visit the ED lab., please feel free to contact us by email.
