Friction and wear behaviors of compacted graphite iron with different biomimetic units fabricated by laser cladding

► Fabricating biomimetic units to form wear resistant surfaces by laser cladding. ► Investigating four different cladding ceramics on friction and wear of biomimetic specimens. ► Reinforced microstructure of biomimetic unit is the main contribution to wear resistance. ► Cladding TiC is the best in anti-wear while cladding B4C is the highest in friction coefficient.
