“…Below this was a mechanically mixed layer (MML) that was several microns thick consisting of an equi-axed nanocomposite of a Cu-rich metallic phase and (Fe, Cr) 2 O 3 -based oxide particles, which was formed by compaction and mixing of wear debris. Below the MML was a severely plastically deformation layer (SPDL) consisting of elongated nanograins of a CueNieSn solid solution [15].…”

“…In other words, the wear resistance of NMCs at 18 N is improved, which is most likely as a result of microstructural evolution. Previous studies show that microstructural changes are observed near the worn surfaces [20], and the most common forms are dislocation substructure [21], mechanically mixed layer [22,23] and NC tribolayer [15,22,23].…”

“…As a result, a mixed layer is produced at the interface. It is well documented that the mechanical mixed layers or tribo-layer often contain oxides and that a continuous oxide layer may be beneficial to reduce friction and wear (Singh,et al (19,21)). Furthermore, it has also been well 3 Si alloys and copper alloys respectively, and found that the formation of the mechanical mixed layer on worn surfaces protected the materials from adhesion and thus resulted in a lower wear rate.…”

This paper provides an in-depth investigation into the formation of the mechanical mixed layer (MML) and its role in Cu-15Ni-8Sn/graphite composites. Wear tests were conducted at room temperature using a ring-block configuration with the applied load of 50 N and sliding speed of 0.42 m/s. SEM, EDS and XPS were performed to analyze the worn surfaces and sub-surfaces.Results indicated that high graphite content contributed to the formation of a protective MML.When the MML formed on the tribo-surface as graphite content increases, both the friction coefficient and wear rate greatly decreased. The friction coefficient with a stable value of 0.075 and wear rate of 6.10×10 -16 (m 3 /N• m) were the lowest when an apparent tribo-layer appeared at the graphite content of 38 vol. %. The characteristics of the MML and its influences on wear mechanisms of the composites are discussed. The MML existing on the worn surface protected the materials from severe adhesion and abrasion, the predominant wear mechanisms changed to delamination, which resulted in the drastic changes in wear resistance and friction coefficient.
