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.
