Advanced tribological solutions for sustainable future

This special issue contains the research articles from the 4th International Brazilian Conference on Tribology (TriboBR 2023), held in Vitória, Brazil, on 26–30 November 2023. Profs Henara Lilian Costa and Cherlio Scandian chaired the conference. This special issue contains 10 selected research articles from TriboBR 2023. The great majority was presented at two sessions, in which Professor Giuseppe Pintaude had acted as Chairman: Automotive Tribology and Tribology in Manufacturing. These two sectors require more attention from tribologists because they deal with energy, efficiency, reliability, and economy. A brief description of all the research articles is presented here.
