In this study, surface corrosion of carved and polished specimens of conventional and high-copper amalgams was investigated. The specimens were studied to detect surface corrosion after immersion in artificial saliva for 48 h or 1 year, and later investigated by SEM. Corrosion was greatest in 1-year-immersed carved conventional amalgam specimens. The surface was very rough with the contours of the particles visible and deep holes opening at the surface. High-copper amalgam specimens showed less corrosion than conventional amalgam specimens.
在本研究中，对传统型和高铜型汞合金雕刻及抛光试件的表面腐蚀情况进行了研究。将试件浸泡在人工唾液中48小时或1年后，对其表面腐蚀情况进行检测，随后通过扫描电子显微镜进行观察。在浸泡1年的雕刻传统型汞合金试件中，腐蚀最为严重。其表面非常粗糙，颗粒轮廓清晰可见，表面还有深孔。高铜型汞合金试件的腐蚀情况比传统型汞合金试件轻。
