Abstract: Influence of
reinforcement on the wear properties of Aluminium-12%Si (LM6) reinforced with
Boron Carbide particles (quantity from 3 to 12wt% in steps of
3wt%; size 40-80mm) was investigated
using a computerized pin-on-disk wear test rig under dry sliding conditions at
room temperature. Cast-iron chill was used. Castings were prepared using dry
sand moulds and particles
were introduced into the matrix using Vortex-Route Method. An attempt to analyze
and evaluate the wear properties of these developed composites with respect to
Cast-iron chill, reinforcement and microstructure, is made. Test results have
shown that the wear properties of these developed composites were appreciably
influenced by the chill and reinforcement. It was found that 9wt% of particles in Aluminium-12%Si (LM6) alloy
exhibited the least wear rate.
Keywords and phrases: wear, dry sliding, boron carbide, reinforcement, chills.
