摘要
The delamination of a model polymer on galvanished steel has been analysed in detail with a scanning Kelvinprobe in the presence of defects, which penetrate the coating and the zinc layer. The delamination rate is determined by cathodic reactions, which destroy the zinc/ polymer interface, and by a subsequent anodic zinc dissolution, which is necessary to cathodically protect the defect (steel). The width of the cathodically protected zone is determined by the scanning Kelvinprobe, too. (C) 2001 Elsevier Science Ltd. All rights reserved.
