Tribology of Self-Lubricating Metal Matrix Composites

Development of a Cu/MoS2/Ni Self-Lubricating Composite Clad through Laser Additive Approach over a Ti6Al4V Substrate and Its Characterizations

“…Also, a large number of grooves and oxide wear debris are distributed over the wear track. Thus, the substrate shows adhesive wear and oxidation wear as the dominant wear mechanisms, while the coating part predominantly shows adhesive wear. − …”

Influence of sintering pressure on microstructure and tribological properties of Copper–Tin composites containing graphite and MoS2

“…It may be inferred that the temperature of the specimen rises as a result of high-speed friction, and Sn oxides form on the friction surface, as shown in particular by the elemental distribution diagram in figure 10 where the distribution areas of Sn and O elements generally overlap. The lubricating film is strengthened through diffusion by SnO 2 , which also increases the film's wear resistance [32]. The friction surface of sample 1 was relatively smooth, and SnO 2 distribution was uniform, so the wear resistance was improved; The friction surface of sample 2 was rough and SnO 2 distribution was uneven, so the wear resistance was poor; The friction surface of sample 3 was very smooth, and the SnO 2 distribution was more uniform, and the content was larger, which promoted the improvement of wear resistance.…”
