[Case] Investigation of the Cause of Discoloration of the Metal Part of the Clipboard

Observation and analysis of discoloration due to metal corrosion! Introducing case studies on the investigation of discoloration causes.

We would like to introduce a case where discoloration due to common metal corrosion was observed and analyzed at our company. Upon observation with a scanning electron microscope (SEM), traces of corrosion were confirmed. This discoloration is presumed to have occurred due to the corrosion of iron material beneath the nickel plating, resulting in the precipitation of rust, which is the product of that corrosion, on the surface. 【Case Overview】 ■Observation of Discolored Area: Magnified view of the discolored area ■Magnified Observation and Elemental Analysis: Further magnified observation and elemental analysis of the discolored area ■Structural Analysis: Structural analysis using Raman spectroscopy ■Cause of Discoloration: The discoloration is primarily due to the corrosion of iron, known as "red rust." *For more details, please refer to the PDF document or feel free to contact us.
