Resumen

El artículo presentó una investigación multianalítica de un conjunto único de herramientas de cobre que se remonta a la Edad Oscura, de la tumba de KHENNU Y APA-EM-SA-F (289) en el sur de Memphis, Saqqara. Se utilizó estereomicroscopio para examinar la morfología de los productos de corrosión de la superficie exterior. Se utilizó un microscopio metalográfico para investigar la microestructura del núcleo metálico y la estratigrafía de las capas de corrosión. Se utilizó SEM-EDX para identificar la composición elemental de los objetos. Se utilizó espectroscopía XRD y Raman para analizar la superficie externa y la corrosión interna, respectivamente. La investigación microscópica reveló que las capas de corrosión consisten en una capa externa, una capa debajo de la superficie y productos de corrosión internos. Cuprita, paratacamita, nantokita, atacamita, malaquita y calconatronita fueron identificadas por espectroscopía XRD y Raman como corrosión superficial e interna. SEM-EDX reveló que los objetos del estudio de caso consisten en metal de cobre sin ningún elemento de aleación adicional. El estudio presentó un tratamiento adecuado para estos objetos friables o tales casos, y luego presentó un procedimiento de fijación seguro mediante una técnica de costura a través de hilos inertes transparentes. Los resultados revelaron que el ambiente de enterramiento y el almacenamiento a largo plazo en un ambiente incontrolado juntos causaron una corrosión progresiva de los artefactos estudiados.
