[Example] Cross-sectional observation of a car door handle cover.

Conducting magnified observation and elemental mapping using a scanning electron microscope (SEM)! Introducing examples of cross-sectional observation.

We present a case study where we created a cross-section to investigate the plating layer of a car door handle cover, followed by magnified observation and elemental mapping using a scanning electron microscope (SEM). For the plated section, we created a cross-section using ion milling and measured the thickness. The total plating thickness was found to be approximately 11-12 μm, with the thin outermost plating (chrome) measuring about 85 nm, and the second layer of plating underneath measuring about 850 nm. Additionally, the elemental mapping results confirmed that the substrate was a thick copper plating, with nickel plating applied on top of it, followed by chrome plating.

[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.

[Example] Measurement of the thickness of chromate treatment film

A chromate layer confirmed on approximately 1μm thick zinc plating! Introducing examples of film thickness measurement.

We would like to introduce a case where we measured the thickness of a chromate treatment film at our company. For colored chromate metal parts, we performed cross-section processing using ion milling, and observed the cross-section using a field emission scanning electron microscope (FE-SEM) to measure the film thickness. When observing the cross-section of the film with FE-SEM, a chromate layer was confirmed on top of a zinc plating of just over 1μm. Further magnification revealed that the thickness of the chromate layer was approximately 420nm. 【Case Overview】 ■Sample investigated: Chromate ■Cross-sectional film thickness measurement: Measurement of chromate film thickness *For more details, please refer to the PDF document or feel free to contact us.
