SYMPOSIUM H
Advanced Characterization Techniques for Coatings and Thin Films

Technical Symposia: A | B | C | D | E | F | G | H
Topical Symposia: TS1 | TS2 | TS3 | TS4 | TS5

Symposium Chairs

Marco Sebastiani, Roma TRE University, Italy, marco.sebastiani@uniroma3.it
Benoit Merle, Friedrich-Alexander University Erlangen-Nürnberg, Germany, benoit.merle@fau.de

This symposium focuses on recent advances in the structural, micro-structural, and mechanical characterization of coatings and thin films, which enhance our understanding of the growth and surface modification processes as well as the fundamental structure-property-processing relationships. Of interest are contributions that either highlight the application of, or draw attention to, recent advances in analytical methods, characterization techniques, and novel nano-mechanical testing methods for coating evaluation. Analytical methods may include numerical evaluation and quantification procedures (e.g., factor analysis, depth profiling, 3D mapping, etc.) to reveal the micro- and nano-structure, chemical composition, residual stress, chemical states, and phases of coatings, thin films, interfaces, and surfaces during or after surface modification. Micro-mechanical methods may include compression, bending, or toughness testing to determine coating behavior, particularly at elevated/service temperatures and in harsh environments, and the relationship to coating performance and lifetime. Residual stress analysis, phase characterization, surface topography probes, compositional analysis, high-resolution spatial imaging and analysis, and hardness measurements continue to be subjects of interest in this session. In-situ characterization methods and other novel techniques presenting the combination between microstructural nano-mechanical probes are highly encouraged.

H1. Spatially-resolved Characterization of Thin Films and Engineered Surfaces

Session Chairs

Michael Tkadletz, Montanuniversität Leoben, Austria, michael.tkadletz@unileoben.ac.at
Xavier Maeder, EMPA, Switzerland, Xavier.Maeder@empa.ch

In this session all aspects concerning novel spatially-resolved structural, microstructural and chemical characterization techniques, especially those ones that advance the in-depth understanding of the relationship between the processing, the structure and the properties of thin films and engineered surfaces. Particular attention will be given to papers providing information on novel cutting-edge experiments on the analysis of the microstructure and microstructural evolution of thin films, including in-situ measurements during film growth, spatially resolved analysis of residual stress and three-dimensional chemical mapping. Emphasis will be given to novel high-resolution techniques, such as Atom Probe Tomography, X-ray nano-diffraction, advanced TEM characterization, micro-Raman spectroscopy, etc. Papers are furthermore also solicited in the emerging area of three-dimensional microstructural characterization in small volumes, such as FIB/SEM tomography, in-situ EBSD and/or ToF-SIMS 3D mapping.

H2. Advanced Mechanical Testing of Surfaces, Thin Films, and Coatings 

Session Chairs

Benoit Merle, Friedrich-Alexander University Erlangen-Nürnberg, Germany, benoit.merle@fau.de
Marco Sebastiani, Roma TRE University, Italy, marco.sebastiani@uniroma3.it

This session covers advanced mechanical characterization techniques for surfaces, thin films and coatings with a focus on the development of novel methods rather than the application of standard methods to new materials. This includes novel methods of performing nanoindentation testing or analysis methods and testing of micro-scale testing geometries produced using focused ion beam (FIB) machining or issues related to the FIB-machined structures. Particular attention will be given to papers providing details on developing techniques such as novel fracture testing geometries. Emphasis will be given to testing techniques performed in situ in the SEM, TEM, Raman, X-ray beamline, etc. Papers are also solicited in the emerging area of nano- or micro-testing at high strain rates.

Invited Speakers

Megan Cordill, Erich Schmid Institute, Austria
“In-situ-squared: Combined Electro-mechanical Behavior of Thin Films with One Experiment”

Karsten Durst, Technische Universität Darmstadt, Germany
“Recent Advances in Micro-cantilever In-situ Bending Experiments”

H3. Characterization of Coatings in Harsh Environments

Session Chairs

Jeff Wheeler, ETH Zürich, Switzerland, Jeff.Wheeler@mat.ethz.ch
James Gibson, RWTH Aachen, Germany, gibson@imm.rwth-aachen.de

Session H3 covers the characterization of the coatings microstructure and mechanical behavior under harsh and/or unusual environments, such as high or cryogenic temperatures and radiation. Particular attention will be given to papers providing characterization in-situ in the harsh environment, rather than ex-situ after exposure: e.g. nanoindentation testing performed at high temperatures rather than after an annealing treatment in a separate furnace. Emphasis will be given to work which shows progress pushing the testing envelope further into harsher environments or combining multiple characterization techniques to gain information on coatings’ behavior under severe or aggressive environments.

Invited Speaker

Daniel Kiener, Montanuniversität Leoben, Austria
“In-situ Study of Deformation and Fracture Processes in Nanostructured Metals at Elevated Temperatures”
