An interesting case study of failure analysis of defect on the surface of some galvanized fuel tank will be published on October 2015 in Case Studies in Engineering Failure Analysis
A peculiar type of edge discoloration defect on the surface of some galvanized fuel tank was observed, causing significant appearance problems. In the study, the surface defect was characterized by visual inspection, optical microscopy, scanning electron microscopy and energy dispersive spectroscopic analysis to understand the source and mechanism of the defect. The paper presents the results of the investigation.
