A common failure mode seen during the testing and operation of spacecraft is termed ‘cold-welding’ (‘coldwelding’, ‘contact welding’, ‘adhesion’, ‘sticking’ or ‘stiction’). Coldwelding is a solid-state welding process in which joining takes place without fusion or heating at the interface of the two parts to be welded. This effect mainly concerns metal-to-metal contacts. It was first recognized as a general materials phenomenon in the 1940s: Clean, flat surfaces of metal might strongly adhere if brought [...]

Ball bearings are essential components in various mechanical systems, designed for their high hardness to ensure wear resistance and the ability to withstand high contact stresses. For many years, this design philosophy served well as long as traditional bearing configurations with predominantly compressive stresses were prevalent. Stress corrosion cracking (SCC) was not a significant concern in such setups. However, as the industry continues to evolve towards more efficient and lightweight integrated solutions, where bearings are [...]
