Abstract
In today's manufacturing landscape, stringent requirements and specifications for mechanical properties and other characteristics have become crucial for top casting manufacturers. This paper focuses on using Scanning Electron Microscopy (SEM) as a powerful tool to analyze internal defects that significantly impact the performance of castings. Specifically, it delves into various aspects of this approach, including the identification of bifilm deficiencies in ductile and chromium cast iron, near-surface corrosion induced by sulfur, micro-shrinkage under risers, remnants of lustrous carbon, and other microstructural features. The paper elucidates the methodology employed to detect these defects, presents the results of their analysis, and explores potential causes behind their occurrence.
