Technical Symposium PP
Symposium PP focuses on plasma vapor deposition technologies, which are central to thin film synthesis and surface engineering. The symposium covers the development and enhancement of established technologies, and novel concepts, as well as advances in diagnostics and fundamental understanding of deposition processes.
PP1. PVD Coating Technologies
This session solicits contributions related to the development of new PVD methods and the advancement of industrially applied technologies. Sputtering, cathodic arc, anodic arc, laser, and electron beam-based methods and their combinations are considered in particular. The session welcomes contributions incorporating topics such as in-situ measurements, plasma transport in electromagnetic fields, plasma diagnostics, and computer-aided process development. Furthermore, the session will cover digital methods to understand and control thin film deposition processes, encompassing topics such as simulations, small and large-scale data analysis, in-situ process feedback control, and real-time optimization related to PVD technologies. Potential application areas include deposition technologies in use for 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.

PP2. HiPIMS, Pulsed Plasmas, and Energetic Deposition
The energy carried to the thin film during deposition is crucial in reducing the growth temperature and improving the 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 e.g., optical, wear-resistant, or photovoltaic applications. This session solicits contributions from academia as well as industry and covers both the physics and the applications of energetic deposition. Topics of interest include plasma generation and discharge physics, plasma surface interaction and diagnostics, modeling and data-driven process understanding and simulations, reactive processes and process control, mechanisms of film growth, surface and interface engineering, industrial applications and production, upscaling, and associated equipment.

We want to span the whole range from applications for DLC or ta-C on engineering components as well as coatings employed in devices and displays or electrochemical applications like fuel cells and electrolytic applications. Deposition technologies include plasma-based methods CVD, PVD, and their combination, arc, ion-beam, and laser-assisted deposition and HIPIMS as well as dip coating, sol-gel, and other transfer techniques. This session includes fundamentals and the development of interfaces between substrate and DLC to improve adhesion, supporting layers, and hybrids with hard coatings, industrial practices, scalability, and cost estimates.

PP5. Microfabrication Techniques with Lasers and Plasmas
Laser and plasma sources provide tunable fluxes of photons, electrons, ions, and radicals available for microscale-controlled or selected-area film deposition, surface etching/texturing, and functionalization. The scope of this session encompasses laser, plasma, and electron/ion beam processes aimed at chemical modification for catalytic substrates and surface engineering to fabricate biomaterials and microelectronic devices. Here, strategies to synthesize nanostructured interfaces enabling few-atom catalysts, organic tissues, and electronic heterostructures, like large-area laser microtexturing and plasma-enhanced atomic layer deposition, will be discussed. This session thereby welcomes contributions on laser, plasma, and particle beam techniques to generate functional interfaces in the domains of atoms, polymer chains, nanoparticles, cells, microchips, and entire tissues, with experimental and modeling approaches. Such a multiscale perspective will enable the design of green, sustainable processes for tailoring surface properties, like microlithography and plasma polymerization, thereby appealing to scientists interested in energy, packaging, and semiconductor applications.

PP6. Greybox Models for Wear Prediction
The prognosis of the wear behavior of coated tools and components is still unsolved and sufficiently accurate models to predict the wear behavior do not yet exist. Methods of machine learning in combination with conventional simulation approaches offer high potential to tackle this issue. By using these methods, the understanding of the wear mechanisms and the forecast of wear development and lifetime can benefit. Consequently, tool and component development as well as machining processes and applications can be improved by an adjustment of the process parameters or by an adjustment of the coatings deposited on the tools or components in order to achieve a higher productivity and a longer lifetime. Regarding wear prognosis, “Whitebox” models, based on physical laws and analytical correlations, represent the state of the art to determine the behavior of, for example, tools during the cutting process. Nevertheless, for a very complex and non-linear system behavior like wear progress of tools, whitebox models are limited. One possibility to predict non-linear behavior is offered by data driven “Blackbox” models, mostly based on machine learning algorithms. To utilize the benefits of whitebox and blackbox models and to overcome the limitations of both, they can be combined into “Greybox” models. This offers great potential to improve prediction accuracy of wear and remaining service life.
The session welcomes contributions that address wear prognosis of coated tools or components by conventional simulation approaches in combination with data-driven models. Emphasis can be directly on greybox approaches or on particular analytical or data-driven models. Of particular relevance will be whitebox models that combine coating properties and behavior in processes and contribute to an increased prediction accuracy of established models. Also, welcome are contributions to blackbox models for high-performance applications with coated tools or components. In particular, the need for blackbox models should be described, and how these models can be combined with whitebox models to form greybox models. Moreover, the greybox modelling approach can be extended to other applications of the coating industry in the future. Contributions to this topic from scientists and from industry in the fields of coating technology, production, mathematics and information technology are very welcome to contribute to the session and present their work.
