Symposium Chairs

Thomas W. Scharf, University of North Texas, USA, Thomas.Scharf@unt.edu 

This symposium covers all aspects of tribology (friction/wear/lubrication), mechanical properties, and adhesion of coatings and engineered surfaces. The scope includes both experimental investigations and modeling of static (indentation/fracture/adhesion/impact) and dynamic (oscillating/scratching/sliding/rolling) contacts, and contact/fracture mechanics across multiple length scales from atomistic to macroscopic. Papers are welcome which contribute to an improved understanding of the science/mechanisms underlying the tribological and mechanical response and performance of engineered surfaces and coatings in addition to papers that explore recent advances in coating design and development for specific applications. Special emphasis is placed upon characterization (friction/wear/lubrication/mechanical properties), of coatings and engineered surfaces, process-structure-property interrelationships, length scale dependence of properties and/or performance, and property/performance mapping. All materials (e.g. metals, ceramics, polymers) are of interest, but additional emphasis is given to multi-functional (hard and lubricious) and nanocomposite coatings for extreme environments, tribological and mechanical properties of nanostructured coatings, diamond and diamond-like carbon, and coatings for advanced aerospace, automotive and machining applications. Papers are also solicited describing instrumentation advances and new measurement techniques across all length scales.

E1. Friction, Wear, Lubrication Effects, & Modeling  

Session Chairs

Juan-Carlos Sánchez López, CSIC-University Sevilla, Spain, jcslopez@icmse.csic.es
Samir Aouadi, Southern Illinois University, Carbondale, USA, saouadi@physics.siu.edu
Vincent Fridrici, École Centrale de Lyon, France, vincent.fridrici@ec-lyon.fr
Osman L. Eryilmaz, Argonne National Laboratory, USA, eryilmaz@anl.gov 

This session covers all the essential phenomena related to contacting surfaces, friction, wear and lubrication. Contributions are solicited that report on the development of materials, thin films or innovative structures to reduce friction. The study of liquid or boundary lubrication for coatings is within the scope of this session. Of particular interest are coating/thin film architectures of multilayered or composite coatings exhibiting nanometer scale hard and solid lubricating features. Particular attention will be given to papers providing new understanding of tribological phenomena of coatings and thin films. Emphasis will be given to contributions proposing some understanding of the role of coating composition and structure in the improvement of tribological properties, such as friction reduction or wear protection, or the achievement of new functionalities (thermal cycling resistance, fracture toughness, oxidation resistance, etc.). Papers are also solicited in the emerging area of mathematical and physical/chemical modeling of tribological interaction at the atomic or molecular level to assist in surface engineering of improved tribological surfaces and coatings.

David F. Bahr, Washington State University, USA, dbahr@wsu.edu
Richard R. Chromik, McGill University, Canada, richard.chromik@mcgill.ca 

This session is devoted to the measurement and modeling of the mechanical properties of the surface and near-surface regions of thin films, coatings, and surface engineered bulk materials. Topics of particular interest include:

• mechanical property mapping using instrumented indentation methods,
• extraction of mechanical properties and constitutive properties by modeling of indentation load-displacement curves,
• novel test methods, such as: micro-pillar compression, MEMS test beds, and in situ testing in SEM or TEM,
• quantitative determination of interface adhesion and residual stresses
• fatigue studies of thin films in microelectronics and MEMS applications,
• microtribology and nanotribology.

Special consideration will be given to papers that address processing-structure-mechanical property relationships across multiple length scales (from the atomic scale upwards).
