Abstract
In this chapter, the characteristic of metals, alloys, and their typical
corrosion are introduced. Then, the protection strategies are proposed for the
conservation and protection of historical metallic artifacts. The protective coatings are
also investigated to prevent electrochemical corrosion in metal artworks from
traditional materials and methods to new nanocomposite coatings. The characteristics
of protective coatings in terms of composition, yellowing, and degradation are
evaluated. Besides chemical stability and protective properties, which are crucial
factors in choosing protective coatings for ancient metal artworks, the principles and
theoretical foundations of protecting and restoring historical monuments sometimes
limit the use of these materials. Therefore, it is necessary to review and evaluate the
materials and methods of coating metal artifacts connected with the theoretical
frameworks of restoration.
Keywords: Corrosion, Historical metal objects, Nanocomposite, Polymer, Protective coatings.
