8. High-temperature gas-solid reactions forming both solid and gaseous products: thermodynamic and kinetic aspects – Applications to corrosion and protection of materials at high

temperature

Aim: to describe an important type of processes almost ubiquitous in the performance of materials under extreme environmental conditions and to discuss examples for selected materials.

Topic explanation and teaching suggestions: Understanding of this topic enables appreciation of high/very high temperature corrosion of metallic and ceramic materials in various extreme environmental conditions, in particular reactive atmospheres (“hot corrosion”). This knowledge is of particular relevance for the fundamental understanding of materials problems related to aerospace (e.g. hypersonic atmospheric re-entry and rocket propulsion) and energy production systems (gas turbines operating at HT, coal gasification, nuclear reactors, etc.). A sound knowledge of thermodynamics and kinetics of gas-solid reactions is also important for chemical vapor transport and deposition processes (see description of the relevant topic described later in this syllabus).
