Symposium B focuses on surface engineering and materials science of hard coatings. We are interested in fundamentals of deposition processes, properties of new single, multilayer, nanocomposite and nanostructured hard coatings, process-structure-property relationships, substrate effects, modeling, and industrial practices.
B1. PVD Coatings and Technologies
This session solicits contributions (except those covered by the topical sessions) related to sputter-deposition, cathodic and anodic arc discharges, laser ablation, electron beam (with and without additional ionization) and combinations of PVD coating methods. We welcome contributions on in-situ measurements, process modeling, plasma transport in electromagnetic fields, and multi-phase, gradient and nanostructured coatings, as well as hard and superhard coatings. Applications include but are not limited to wear-protective coatings for components and tools, low-friction thin films, high-temperature wear-, erosion-, and corrosion-resistant coatings, optical layers, biomaterials, decorative coatings, and materials for energy applications.

B5. Hard and Multifunctional Nanostructured Coatings
This session solicits contributions related to nanostructured and nanocomposite coatings as well as multicomponent and layered films with morphological designs adapting the microstructure down to the nanoscale level. The desired functionalities range from structural properties such as high hardness, toughness, or thermal stability to chemical inertness up to adaptive mechanisms like controlled friction as well as sensing properties. The session not only emphasizes the design and synthesis of novel coating concepts but also their characterization, modeling, and applications. In addition, combined functionalities such as self-adaptive mechanisms based on phase transformations within specific architectures – just to mention one possibility – are highly appreciated to explore the next level of multifunctional coatings.

We are interested in both experimental and computational studies of knowledge-based chemical and structural design approaches. Studies on growth kinetics, prediction and explanation of structure and properties of surfaces, interfaces, and thin-film material systems, as well as the thermodynamic processes involved, as well as coating process technologies are particularly welcome.

B7. Plasma Surface Interactions, Diagnostics and Growth Processes
Plasma diagnostics of materials synthesis and modification processes provide important insights on processing-structure-property relationships. The objective of this session is to show the utility of such correlations. Talks featuring new plasma diagnostic techniques, characterization of plasmas in novel processes, and correlation of intrinsic plasma properties to the structure and composition of materials are welcome.

B8. HiPIMS, Pulsed Plasmas and Energetic Deposition
Energy carried to the thin film during deposition is crucial in reducing the growth temperature and improving properties of thin film materials. Higher plasma density leads to enhanced ionization of the film precursors and offers better deposition process control. This results in improved coating characteristics, valuable for e.g. optical, wear resistant, or photovoltaic applications. This session solicits contributions from academia as well as the industry which cover both the basic physics and the applications of energetic deposition. Topics of interest include, but are not limited to: plasma generation and discharge physics, simulation and modelling, reactive processes and process control, mechanisms of film growth, surface and interface engineering, industrial applications and production, up scaling and associated equipment.
