| Description |
An attempt has been made to understand the mechanism of material removal during two-body abrasive
wear of Al-alloy (LM13)-SiC composite under varying experimental conditions through the wear
surface and subsurface examination. It has been noted that the mechanisms of material removal during
the wear process are primarily cutting and plowing, which lead to formation of continuous wear
grooves. In the composite, SiC particles act as protrusions over the surface and protect the matrix
from wear. But at higher applied load, coarser abrasive size, and larger sliding distances, some of the
SiC particles get fractured into fine particles and scooped off from the wear surface leading to a
higher wear rate. The subsurface studies show severe plastic deformation and finally formation of a
mechanically mixed layer (MML) over the plastically deformed zone. The MML gets fractured during
the wear process and finally removed by the formation of lateral and transverse cracking. The cracks
are generally initiated at the interface of MML and the plastically deformed zone and propagate along
the weaker region in MML. The material removal mechanism has been schematically presented in
order to have a better understanding.
