Wear resistance analysis of the aluminum 7075 alloy and the nanostructured aluminum 7075 - silver nanoparticles composites
Nanostructured composites of the aluminum 7075 alloy and carbon-coated silver nanoparticles were synthetized by the mechanical milling technique using a high-energy mill SPEX 8000M; the powders generated were compacted, sintered and hot-extruded to produce 1 cm-diameter bars. The composites...

| description | Nanostructured composites of the aluminum 7075 alloy and carbon-coated silver
nanoparticles were synthetized by the mechanical milling technique using a
high-energy mill SPEX 8000M; the powders generated were compacted, sintered
and hot-extruded to produce 1 cm-diameter bars. The composites were then
subjected to a wear test using a pin-on-disc device to validate the
hypothesis that second phase-ductile nanometric particles homogenously
distributed throughout the metalmatrix improve the wear resistance of the
material. It was found that silver nanoparticles prevent the wear of the
material by acting as an obstacle to dislocations movement during the plastic
deformation of the contact surface, as well as a solid lubricant when these
are separated from the metal-matrix. |
