Wear behavior of Al-12Si/TiB2 coatings produced by laser cladding

► Microstructure, hardness and wear of laser clad Al-12Si/TiB2 coatings were studied. ► Microstructure presents TiB2 dispersed in α-Al dendrites and α-Al + Si eutectic. ► Microhardness is 156 HV and sliding wear coefficient is 2.65 × 10−5 mm3/(Nm). ► Wear mechanisms are asperities oxidation, their fracture and tribolayer formation. ► Brittle fracture and detachment of tribolayer lead to material removal.
