A2.12

(Α2.1+Α2.11)

Purpose of the Course:

The purpose of the course is to review the nature and characteristics of materials as well as the parameters, such as structure and processes, that affect the properties of materials. The study of the corrosion of metal objects, the knowledge of atmospheric pollutants as well as their possible effects on the artworks of the exhibition spaces.

Educational Objectives:

Upon completion of the course students should know about the different groups of materials and how their structure and processes affect the properties of these materials and the pathology of the components of works of art.

Course Analysis:

In the context of the course, a review is made of the nature and structure of materials as well as the parameters that influence their properties. Metal materials are the main study model, but individual references are also made to the other categories. Among the key concepts and areas covered are the crystal structure of solids, diffusion, selected physical and mechanical properties and their relationship to microstructure, presence of phases and treatment (mechanical and thermal) of the material, equilibrium phase diagrams, major classes of metals materials (e.g. iron alloys, copper, etc.), corrosion, oxidation and methods of their protection. They will also study:

– Corrosion occurrence conditions and types of corrosive environment, thermodynamics and kinetics of corrosion, selective predisposition of alloys and metals to corrosion, mechanisms and types of corrosion, methods of protection against corrosion, methods of restoration of metal objects.

– The physical, chemical, biological and other factors that affect the constituent materials of works of art and other related structures.

– The main and secondary pollutants of the reaction cycle of sulfur and nitrogen, their reactivity in air and between air and surface.

– Air pollution and marine aerosols, case studies.

– Criteria and methods for measuring the environmental factors that cause damage. Monitoring of climatic and microclimatic parameters, temperature, humidity, gaseous pollutants.

– Study of the transport and deposition mechanisms of gaseous pollutants
