JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

This lab course is mainly designed to conduct the practicals like electro

deposition, verification of Faraday’s laws and evaluation of factors affecting corrosion

Course Outcome:

Through this laboratory practice, the student will be able to judge the process variables like current efficiency, current density to obtain desired electro deposition. Also the student will lay hands on the equipment designed for evaluation of corrosion studies.
