“…The identification of the steady state regime (SSR) of the micro-scale abrasive wear tests was determined by analyzing the graph of the wear coefficient (k) as a function of the sliding distance (S). In addition, the graph of wear volume (V) as a function of the sliding distance was used for the verification of obtaining the SSR [29,30]. The wear coefficient tends to a constant value as the sliding distance increases, as shown in Figure 8 Due to the fact that the SSR is achieved when the variation of the VMR as a function of the sliding distance shows linear behavior, and R 2 values near the unit were obtained, it can be assumed that the SSR was really achieved for all tested conditions.…”

The idea for this work came from a market need to obtain coatings or sealants that would extend the useful life of metallic materials in applications that involve exposure to corrosive environments. The main objective of the nanoceramic sealant studied in this work is to extend the life of metallic fasteners. To evaluate the performance of the sealant from other perspectives, microstructural analysis, adhesion test, micro-scale abrasive wear tests and corrosion test were carried out. These tests were performed on samples coated only with white zinc, which is commonly used in the fastener industry, and on samples coated with white zinc followed by application of the nanoceramic sealant. The application of the nanoceramic sealant contributed to the improvement of corrosion resistance and reduction of the corrosion rate. The corrosion rate of the sample coated with the sealant reduced by 62.2% when compared to the sample that only went through the white zinc coating process. The coating showed low adhesion to the substrate with the presence of severe delamination and microcracks. This feature contributed to the low wear resistance presented by the coating under the conditions studied in this work. Less attention, compared to studies involving corrosion resistance, has been given to wear resistance in the fastener industry. The results obtained in this paper show that the study of tribological behavior is an important factor in increasing the efficiency of fasteners applied in harsh environments.

“…The Tribology research group of Universidade do Estado de Santa Catarina (UDESC) has conducted research on Tribology, Surface Engineering and Powder Metallurgy since 2009. The group develops studies considering improving materials' tribological behaviour through surface changes, increasing materials' tribological performance, especially in parts produced by powder metallurgy [333,[358][359][360][361][362][363][364]. The group has been developing niobium-based tool materials (cermets) [365][366][367][368] and zinc-aluminium alloys [369].…”

This first regional issue published in STMP highlights the potential and importance of the research carried out in Latin America regarding surface engineering and tribology. In order to celebrate this important initiative, a complete historical account of Brazilian tribology is presented for the first time. It initiates with the first steps of Brazilian tribology in the 1980s, followed by the evolution and expansion of tribology research both in academic centres and industry. Focus is given to two outstanding achievements of Brazilian tribology: the fully flexible engines that run at any proportion of ethanol and gasoline and a fully innovative, completely oil-less family of hermetic compressors. The status-quo of the current research groups on tribology is described. Finally, the future trends envisaged by the Brazilian tribology community are presented.
