On the project
Většina selhání tribologických uzlů souvisí s procesy opotřebení, které jsou však pouhým důsledkem procesů tření a mazání. Primární snahou je snížit tření a opotřebení, tj. zajistit mazání za podmínek superlubricity. V současnosti se materiály a maziva, vykazující superlubricitu, testují převážně na nanoúrovni, případně na mikroúrovni. Pro lepší poznání za podmínek, ve kterých pracují běžné stroje, je třeba provést detailnější výzkum na makroúrovni.
