Ann Bolcavage, Rolls-Royce Corporation, USA, ann.bolcavage@rolls-royce.com

Addresses coatings and other surface modifications whose primary purpose is to sustain system performance under high-temperature and harsh thermo-chemical environments.  These include high-temperature ageing and stress, corrosion (e.g., oxidation, sulfidation, carburization, water-accelerated degradation), catalytic and physical fouling (e.g., coking, ash fouling, slagging), and wear (e.g., abrasion, erosion, impact).  Topics of interest cover the characterization and mechanistic understanding of a wide range of high-temperature degradation phenomena, as well as the materials science and surface process technologies to ameliorate them.  Typical applications span gas/steam turbines, coal, geothermal, and biomass energy conversion, chemical/petrochemical processes, and high-temperature batteries and fuel cells.

A1. Coatings to Resist High Temperature Oxidation, Corrosion and Fouling

Session Chairs:

Ying Zhang, Tennessee Technical University, USA, yzhang@tntech.edu
John Nicholls, Cranfield University, UK, j.r.nicholls@cranfield.ac.uk

Lars-Gunnar Johansson, Chalmers University of Technology, Sweden, lg@chalmers.se

Dmitry Naumenko, Forschungszentrum Jülich, Germany, d.naumenko@fz-juelich.de

This session spans all aspects of design, processing and performance of coatings to resist elevated temperature oxidation, corrosion and fouling. Topics include composition and processing optimization, effects of applied stress, characterization of coatings and reaction products, new processing methods, and modeling of fabrication and degradation processes (e.g., coating-substrate interdiffusion, thermal cycling, water-accelerated degradation, phase and microstructural stability).  Applications include gas and steam turbomachinery, diesel engines, petrochemical and gasification plants, geothermal energy, waste incinerators, boilers and metal-forming industries. Papers addressing issues as well as solutions are encouraged, with focus on coatings and surface modification.
