Surfaces of modern metals in Heritage conservation questionnaire

2015 12 16 18 34 14

This questionnaire is an attempt to access how the heritage conservation community understands the surfaces of modern metals. It is being conducted by David Hallam as part of a project  on the Recognition and History and technology of oxide coated modern metals.

Oxide coated modern metals

What are modern metals?

Any metal or major new alloy grouping commercialised after 1851. They may be the core of an object (as in stainless steel) or just the very surface as in metal coated plastic.

I consider oxide coated modern metals to be those that are primarily used in a bare state in such a way that the oxide is the primary interface with the environment. These metals maintain their stability thru the passive nature of this oxide. The oxide may be as a result of the alloy constitution or may be synthetically produced.
