Dry sliding wear of nanostructured Fe30Ni20Mn20Al30

An Overview of Dry Sliding Wear of Two-Phase FeNiMnAl Alloys

“…The next layer is a mechanically mixed layer with some zirconia particles embedded in it. A similar tribology was observed when testing Cu-15wt%Ni-8%Sn against zirconia [4]. Beneath the tribolayer is mainly the original pin material.…”

“…The worn surfaces of the pin looked significantly different on pins tested in argon and in an oxygen-containing environment, presumably because of oxide layers on the surface of the pin in the latter case [4,5]. Figure 6 shows an example of these differences.…”

“…The annealed Fe 30 Ni 20 Mn 20 Al 30 perhaps shows a slightly lower wear rate even though it is only 6% harder than the cast alloy at room temperature. However, the higher temperature mechanical properties may be more important since calculations suggest that the temperature at the tip of the pin is >750K [4,5]. It is worth noting that the annealed Fe 30 Ni 20 Mn 20 Al 30 shows a lower ductile to brittle transition temperature than the as-cast alloy [2].…”

“…In two previous papers the dry sliding wear of Fe 30 Ni 20 Al 20 Al 30 [4] and Fe 30 Ni 20 Mn 35 Al 15 [5] was studied in different environments using pin-on-disk wear tests with an yttria stabilized zirconia disk. Unfortunately, in those papers pins of different geometry were used and so it was impossible to compare their wear rates.…”

Surface roughness effect on the friction and wear of bulk metallic glasses

“…3b and 4b) had experienced plastic deformation during grinding/preparation prior to a sliding test which increased the plastic strains of the surface materials. The increased plastic deformation/toughness in the materials promotes the wear resistance and friction, when the wear is controlled by toughness/ductility [11,29]. It has been reported that prior plastic deformation could significantly increase the plasticity of BMGs [30,31].…”
