Technology enabling machinery to operate stably in harsh environments such as high and low temperatures
Machinery operating in harsh environments such as high or low temperatures faces challenges in controlling friction and the resulting material damage, necessitating new materials and friction systems. We are researching “new carbon materials and friction systems” to achieve low friction and wear resistance. Structures giving potential to function in severe conditions have been identified, and future applications in new machinery operating under extreme environments are anticipated.
Mechanical components that generate friction through sliding significantly impact stable machine operation and energy consumption. Particularly in aerospace machinery operating under harsh conditions such as high or low temperatures, controlling friction and the resulting material damage is challenging, necessitating new materials and friction systems.
Carbon materials exhibit extreme properties in strength, low friction, and heat resistance through microstructural control. We are researching the creation of new carbon materials and friction systems to achieve low friction and wear resistance in harsh environments. The creation of carbon materials involves attempting to control structures at the atomic level using various carbon precursors. Furthermore, since the properties of friction and wear depend not only on the original material structure but also on significant structural changes occurring between two surfaces during friction, we focus on analyzing structural changes during friction. This allows us to understand the mechanisms involved while aiming to create new ideal structures.
Micro-scale spherical structures and other architectures capable of functioning in harsh environments have been identified. Beyond enhancing efficiency through application to existing mechanical systems, these discoveries will contribute to realizing future “new machinery worked in extreme environments.”
