I am searching literature for pure nickel coating and Ni-P coating on pure copper and I found few works on Ni-P coating but did not find anything on pure Ni coating on copper. Moreover, people use Chromate coating along with Ni coatings for pouch cell battery tabs but I am not able to find any literature on the corrosion perforation of chromate coatings used for pure copper. Any one can help me by sharing few good articles on this?
