Functional grade composites Cu–10Sn–5Ni reinforced with 10 wt%SiC and 10 wt%Al2O3, respectively, and their alloy was developed through horizontal centrifuge cast technique. Sample composites and alloy were cast at cylindrical dimensions of Φout100 × Φin70 × 100 mm. They were later subjected to tribology analysis during non-lubricated sliding. Anti-wear performance variations at inner (0–8 mm) and outer (8–15 mm) wall thicknesses...Read More

The functionally graded Cu-11Ni-4Si/10wt%WC composite and its alloy have been synthesized using horizontal centrifugal casting technique to compare the mechanical and tribological improvement and its utility for bearings and bushes. Microstructure analysis and mechanical tests showed 43% improvement in hardness and 160% improvement in tensile strength at inner radial distances...Read More

This study investigates the mechanical and tribological properties of a functionally graded Cu–Sn–Ni/Al2O3 metal matrix composite, synthesized using horizontal centrifugal casting technique with dimension Φout100 × Φin85 × 100 mm. The microstructure was examined along radial distances at 1, 8, and 13 mm from outer periphery. Specimens were tested for tensile strength from outer (1–8 mm) and inner...Read More
