It is extremely important that these automated and semiautomated industrial cyberphysical systems operate safely without risk to human life or compromising productivity. Critical infrastructure and critical manufacturing facilities are potentially subject to all types of attackers (state-sponsored cyber attackers and cyber criminals, terrorist groups, hacktivists) who, whether for political, economic, or ideological reasons, select the attacked establishment, thus 2024-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/25730 Effect of loading conditions on the scratching behaviour of a TiBN and different DLC top-layered coatings applied on X210Cr12 cold work tool steel Fülöp, Fruzsina; Maros Berkes, Maria Coatings and coated tools are more and more commonly used in the automotive industry due to their performance-increasing ability. During their application, they have to perform good tribological resistance, including scratch resistance, which may be influenced by many factors such as loading force, type of coating, etc. In the current research work, we investigated the scratching behaviour of four different industrially applied wear-resistant coatings – TiBN, TiBN+DLC, TiAlN+DLC, and CrN+DLC – under different constant loadings of F = 10, 15, 50, and 100 N. Based on the obtained results, we established that the monolayer TiBN has a higher resistance to scratch loading than the DLC top-coated systems. Morphological failure analysis revealed that the damage mechanism of the multilayer coatings with di 2024-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/25729 Some Insights into the Scratch Resistance Assessment of Polycrystalline Diamond Coatings Jalalova, Pusta; Berkes Maros, Maria This study explores the scratch resistance and adhesion performance of polycrystalline diamond (PCD) coatings, crucial for their application in demanding industrial environments. Applying instrumented scratch testing, a practical, quick, cheap, and reliable test method, the adhesion strength of PCD coatings on steel substrate is assessed. Recognizing the limitations of the conventional scratch testing using a diamond stylus when applied for PCD coatings, a modification, namely the use of a stainless steel ball as a scratching tool, and its applicability for characterizing the scratch behavior of PCDs are discussed to offer a simpler and more economical way for tr 2024-01-01T00:00:00Z http://hdl.handle.net/20.500.14044/25728 Production's risk mitigation on the field of Automotive Industry Gal, Istvan; Hima, Zoltan; Tick, Andrea Due to its dynamic nature and complex supply chains, the automotive industry faces many production risks that can significantly affect operational efficiency and product quality. Vehicle production is highly demanding in terms of energy and raw materials. This paper examines the risks in the automotive industry, presents strategies that can be used to reduce these risks, since the goal is to increase flexibility and ensure a smooth production process. The adequacy of supply chain management, quality control, technology adoption, workforce training and regulation in its critical areas are examined, which cover the manufacturing process. The implementation of these strategies is crucial for automakers to effectively manage uncertainties, maintain high production standards, and maintain their reputation against competitors. By emphasizing the proactive measures presented, continuous improvement and collaboration with key stakeholders, automakers can strengthen their manufacturing processes against potential disruptions, ensuring sustainable growth, sustainability, and success in a highly evolving industry. 2024-01-01T00:00:00Z
