This symposium covers all aspects of tribology and mechanical property assessment of coatings and thin films.  The scope includes sliding, rolling, impact, rotating and cutting surfaces of metallic, ceramic, and polymeric materials. Papers are welcome in the general topic areas of tribological coatings and recent advances in their design, development, mechanical assessment, characterization, and applications. Special emphasis is placed on friction, wear, and lubrication of coatings, multi-functional coatings for severe tribological environments, mechanical characterization of tribological coatings, friction and wear mapping, tribology of diamond, diamond-like carbon, and related coatings, amorphous and nanostructured coatings, and coatings for advanced machining applications. Papers dealing with surface engineering and modeling to improve performance of tribological coatings as well as studies of tribology and mechanical properties of coatings in the nanoscale regime are also solicited.

E1. Friction and Wear of Coatings: Lubrication, Surface Effects, & Modeling 

Session Chairs:

Juan-Carlos Sánchez López, CSIC-University Sevilla, Spain, jcslopez@icmse.csic.es Ryan Evans, Timken Company, ryan.evans@timken.com
Samir Aouadi, Southern Illinois University, Carbondale, saouadi@physics.siu.edu

This session is dedicated to the study of friction and wear of solid lubricating or antiwear coatings and thin films. Contributions are solicited that report improvements in tribological performance for a range of applications, by using innovative materials or structures. Particular attention will be given to papers providing new understanding of tribological phenomena of coatings and thin films. Papers that provide correlations between process parameters, chemical/physical/microstructural properties, mechanical properties, coating/substrate adhesion, and tribological performance are encouraged. The study of liquid or boundary lubrication for coatings is within the scope of this session. Papers are also solicited in the emerging area of mathematical modeling to provide wear maps and to assist in surface engineering to design coatings with optimal tribological performance.

E2. Mechanical Properties and Adhesion 

Session Chairs: 

Ming-Tzer Lin, National Chung Hsing University, Taiwan,  mingtlin@dragon.nchu.edu.tw    Johann Michler, Empa, Switzerland, Johann.Michler@empa.ch

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: 1) mechanical property mapping using instrumented indentation methods, 2) extraction of mechanical properties and constitutive properties by modeling of indentation load-displacement curves, 3) novel test methods, such as: micro-pillar compression, MEMS test beds and non-destructive, laser and acoustic techniques, 4) quantitative determination of interface adhesion and residual stresses and 5) modeling of fracture mechanics and dynamic impact. Special consideration will be given to papers that address processing-structure-mechanical property relationships across multiple length scales (from the atomic scale upwards).

E3. Tribology of Nanostructured  & Amorphous Films

Session Chairs:

Vincent Fridrici, École Centrale de Lyon, vincent.fridrici@ec-lyon.fr
Osman L. Eryilmaz, Argonne National Laboratory, USA, eryilmaz@anl.gov

This session focuses on recent advances made in both fundamental and applied tribological studies and practical applications of amorphous and/or nanostructured coatings and thin films. Nanoscopic solid lubricant and hard materials of special interest include diamond-like carbon, nanocrystalline diamond, carbon nitride, carbon nanotubes, metal carbides/nitrides, refractory metal oxides, borides (e.g., Ti-, W-, Zr-) and related materials and composites. Of particular interest are coating/thin film architectures of multilayered or composite coatings exhibiting nanometer scale hard and solid lubricating features. 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. The role of operating conditions, such as thermal cycling and load/speed dependency, and environment, such as inert and oxidizing, is within the scope of this session with the achievement of multifunctional or environment-insensitive tribological coatings being of high interest. In addition, the session will focus on bridging the gap between tribological experiments and tribochemical characterization with macro, micro and nanoscopic behavior.

E4/G4. Coatings for machining advanced materials and advanced manufacturing Methods 

Session Chairs:

Mirjam Arndt, OC Oerlikon Balzers AG, Liechtenstein, mirjam.arndt@oerlikon.com
Xueyuan Nie, University of Windsor, Canada, xnie@uwindsor.ca

This session should focus on recent developments in coatings, deposited by PVD, HPPMS, CVD and hybrid coating technology, to fulfill the demands in the manufacturing industry, i.e. machining of CFRP/Ti, CFRP/Al, titanium and nickel based alloys, dry machining, machining austempered ductile iron (ADI) or CGI, hot forging, forming of hardened steels and lightweight materials, die casting, and plastic injection molding. Current coatings must be tuned to operate effectively under extreme conditions like high temperature, high pressure, intense chemical or mechanical wear, and a combination of those. Contributions should emphasize tribological and wear aspects of hard, superhard, nanocomposite and lubricious coatings with respect to their mechanical and physical properties.

Junhee Hahn, Korea Research Institute of Standards and Science, South Korea, juny@kriss.re.kr  

Papers are solicited on recent advances in the field of nanotribology and microtribology. Papers on microscale and MEMS/NEMS device tribology are also encouraged. Nanoscale studies of friction, wear, adhesion, and surface physics/chemistry are of particular interest. Studies of lubricious thin films and hard coatings to mitigate failure in extreme environments (e.g, elevated temperature, high humidity, vacuum etc.) are also sought. Advances in instrumentation and new measurement techniques on the micro and nanoscales are encouraged. The session is intended to extend understanding of tribological phenomena to the micro/nanoscales to enable future miniaturization of advanced systems, and places emphasis on advanced measurement systems and techniques that advance the state of the art.
