Electrochemical surface treatment and coating techniques such as electroplating, anodising or currentless conversion coating formation offer numerous possibilities to specifically change and improve physical and chemical properties of technical surfaces. Understanding the interactions at the electrolyte/substrate interface including the effects of electrolyte, electric regime and substrate is vital to achieve tailored composition and structure for the optimal performance of surfaces in service, e.g. resistance against corrosion and wear, optical properties, biological compatibility etc. This is crucial to obtain innovative high-quality products and to ensure the responsible use of resources in energy-efficient production processes, which are economically, environmentally and socially sustainable.
After receiving his diploma in Mechanical Engineering in 2011, Maximilian Sieber became a research associate in the Materials and Surface Technology Group at Technische Universität Chemnitz. The research was focused on the development of electrolytes and electric regimes for electrochemical surface treatment processes (anodic oxidation, plasma electrolytic oxidation, electrodeposition). The process parameters were interrelated with structure, composition and the resulting service properties of the produced coatings, mainly regarding corrosion and wear resistance. In-situ diagnoses of the coating processes were performed by high-speed acquisition of pulsed current and potential signals and superimposing electrochemical impedance spectroscopy on the applied electric regimes. In 2016, he finished his PhD-thesis “Electrochemical model for the conversion of aluminium by anodic oxidation” under supervision of Prof. Thomas Lampke.
Afterwards, he joined the German company EXCOR Korrosionsforschung GmbH, a supplier of temporary corrosion protection solutions with specialisation on the VCI method (volatile corrosion inhibitors). As a scientific collaborator, he was involved in analysis and development of test methods to understand and improve the corrosion protection effect of VCI-containing packaging materials like films, papers, cardboards, diffusers etc. in service.
In December 2020, he has joined the Surface Technology Group in the Department of Materials and Manufacturing at JTH.
