Conserving Archaeological Metals
Take a moment to watch the small bubbles coming off the metal artifacts inside this tank. You're witnessing an electrical and chemical reaction that converts rust and other corrosion products into a more stable form. Electrolysis, or electrolytic reduction, is an electrochemical process that can be harnessed to clean and conserve corroded archaeological material. The process involves passing ...
If the metal artifact is highly corroded this conversion may result in the loss of surface detail, an undesirable consequence. Metallic products that are formed on the surface of the artifact are sometimes beneficial and aesthetic, at other times they can obscure surface details or can be somewhat unnatural looking (such as those formed when ...
Recognizing Active Corrosion
Metal corrosion can be active or inactive. Some objects may be corroded but stable, and therefore inactive; others may be actively corroding. An important part of preventive maintenance of metals is to recognize the early stages of destructive, active corrosion. Very few shiny metal artifacts will ...
Understanding the corrosion mechanism of iron artifacts using Mssbauer ...
A cross-sectional analysis of the corrosion layers on an artifact was performed to better understand the corrosion products and their formation mechanisms. The products formed in different sections ( metal , intermediate, and surface) of the corrosion layers on the iron artifact were identified, and a corrosion mechanism was proposed.
The transformations of corrosion products are often accompanied by subtle changes in geometry and porosity, opening ways for oxygen to penetrate more easily and access the remaining metallic core of the artifact [3, 4].
