Castings Defect Analyses

Abstract:

The aim of the contribution is to use metallographic analysis to determine the root cause of the castings’ defects. The paper will show two cases of defects occurring in the ductile iron castings with surface treatment such as galvanizing and painting. Defects were observed on both the inner and outer surfaces of the castings. Light (LM) and electron microscopy (SEM) was used for individual analyses, including measurement of the local chemical composition by the EDS analysis.
