Enhancement of Hardness and Moderation of Surface Defects of 14K, 18K Yellow Gold Alloy by Heat Treatment Ahn, Ji-Hyun; Seo, Jin-Kyo; Ahn, Yoeng-Gil; Park, Jong-Wang;
In this study, we conducted heat treatment on 14K, 18K yellow gold alloy at various temperature conditions for improving their hardness and moderating their surface defects. Also after the heat treatment we used EPMA (Electron Probe Micro Analyzer), XRF (x-ray Fluorescence spectroscopy) for qualitative analysis and OM (optical microscope), SEM (scanning electron microscope) to investigate the changes of surface grain boundary. We used Vickers hardness tester to verify the changes of hardness. After the heat treatment, 14K, 18K gold alloys showed improved hardness and moderated surface defects at specific temperatures and duration.
