Abstract
Friction and wear are responsible for approximately one-fourth of the global energy losses. According to Holmberg et al., these losses correspond to 119 EJ of the world’s total energy consumption from tribological contacts, based on the main sectors: transportation, manufacturing, power generation and residential. In this case, 20% (103 EJ) is used to overcome friction and 3% (16 EJ) is used to re-manufacture worn parts due to wear-related issues. These global energy losses have a huge impact on economic and ecological aspects. Figure 1 summarizes the impact of friction and wear on energy consumption, generated costs and CO2 emissions.
