| Abstract: |
Today’s mobility applications, the energy sector and production processes put increasing demands on components and tools. These demands usually require a combination of friction and wear reduction. In various fields, thin physical vapor deposition (PVD) coatings provide the performance to achieve these goals. Regarding components of tribological systems, triboactive coatings and self-lubricating coatings are in the focus of research. Triboactive coatings combine the high wear resistance of PVD hard coatings with the ability to interact with lubricant additives and enable the formation of friction and wear reducing reaction layers. Self-lubricating coatings provide solid lubricants to the tribological contact and extend the field of dry-running applications. In machining and forming processes, wear resistant hard coatings are used for decades. However, to withstand increasing cutting parameters and dry processes, friction reduction becomes increasingly important. Current research focuses on self-lubricating coatings, which contribute to reduce process forces while providing high wear resistance. The ability of thin PVD coatings to combine friction and wear reduction in various applications is key for achieving the efficiency demands of today and tomorrow.
