The rapid growth of electric mobility introduces unique challenges for lubricants, distinct from those in internal combustion engines. Key requirements include electrical compatibility to prevent short circuits, superior thermal managementto handle heat generated by batteries and motors, and material compatibility with plastics and seals. Lubricants must also address noise, vibration, and...
The study investigated a water-based lubricant specifically designed for power tools, such as diamond drilling tools used in the construction industry. The water content in the lubricant enhances heat transfer capabilities and provides superlubricity, thereby improving thermal management and gearbox efficiency during operation. The formulation was evaluated using standardized ASTM laboratory...
In this study, friction and wear of conventional and alternative high performance polymer compounds for compressors were investigated in gaseous hydrogen and nitrogen up to 80 bar of gas pressure. The compounds used were a commercial PEEK matrix with 10 wt.% each of PTFE, graphite, and short carbon fibres (Polytron), a PPS matrix with 10 wt.% each of PTFE and graphite (MOCOM), and an...
The deployment of hydrogen as a sustainable alternative to fossil fuels demands the use of materials that can ensure safety, durability, and performance across a range of operating conditions. Thermoplastic polymers are increasingly used in hydrogen infrastructure and components due to their chemical stability, low weight, and processability. However, their tribological performance...
