[Case Study] Surface Cross-Section Analysis of Brass with Zinc Depletion
Copper (Cu) is distributed in the areas where zinc has been removed! We will introduce examples of surface cross-section analysis.
This is a case study on the corrosion of brass products using a copper chloride aqueous solution, focusing on the areas where dezincification occurred, including surface observation and cross-sectional analysis. The corroded areas show white corrosion products due to the corrosion of zinc. Observations with a digital microscope revealed traces of immersion at the boundary between the corroded and normal areas. Element mapping results from the cross-section where dezincification occurred confirmed that the surface is covered with corrosion products of zinc, while copper (Cu) is distributed in the areas where dezincification took place. [Case Summary] - Observation of Corroded Areas: Observing the boundary of corrosion - Magnified Observation and Element Analysis: Further magnified observation and elemental analysis of the corroded areas - Element Mapping: Investigating elemental distribution in the cross-section *For more details, please refer to the PDF document or feel free to contact us.
