Development of a new non-destructive method for analysis of the atmospheric corrosion and corrosion protection of copper and copper alloys

Objective


As a contribution to the increasing efforts for the conservation of historical monuments and other metallic objects a research programme is proposed aiming at a novel non-destructive in-silu analytical method for control of patina layers as well as of effects and durability of protective organic coatings interacting with the metal, the corrosion layer (patina) and with the environment. The main part of the project will be the development and application of a new non-destructive, in-situ, analytical method on the basis of the photothermal deflection spectroscopy.


Results of this method will be calibrated by means of standardized artificially produced patina layers on bronze substrates such as cuprite, antlerite, brochantite and defined mixtures of these compounds and of standardised organic coatings and shall then enable a reliable, easy, fast, and non-destructive control of patina and protective layers on real bronze monuments or other metallic objects exposed to atmosphere. Besides the development of this new technique, the special progress of the proposed programme will be an ample application of various, complementary, standard microrange and microanalytical techniques available at the three coopersting institutes. Such combined techniques have been used rarely up to now for the problems under consideration. The precompetitive equipment and procedures to be developed in the proposed project are expected to find a widespread applicability in the field of protection of metallic objects and cultural monuments.
This application will enable a review of previous conservation measures and technologies as well as an assessment of environmental risk factors leading to dangerous surface damages of historical metal monuments.
