Purpose: Many methods are well-known for surface consolidation of aluminium alloys. Fabrication of the new surface layers on aluminium alloys with high hardness and good tribological properties are presented in this paper. Design/methodology/approach: In that aspect, the conception of creating the surface layers containing manganese, nitrogen and oxygen (Mn-N-O) on AlSi13Mg1CuNi alloy used in production of the internal-combustion engine pistons was considered and described. Findings: The (Mn-N-O) layers are structurally connected by diffusion with aluminium base, demonstrates a zonal microstructure with the surface hardness about 358 HV0.01. The (Mn-N-O) layers increase significant the wear resistance of AlSi13Mg1CuNi alloys in frictional association with grey cast iron (hardness 197 HB) and simultaneously decreases the corrosion resistance in 0.01 M solution H2SO4. Research limitations/implications: In the future tribological researches should be applied also another materials as anti-specimens, for example spheroidal cast iron with chromium or molybdenum coatings. Practical implications: The (Mn-N-O) surface layers can be recommended as the tribological layers limiting the abrasive wear of the machine parts made from aluminium alloys. Originality/value: In the article performed the fabrication method of the new (Mn-N-O) surface layers and its beneficial structural and tribological properties for increase the wear resistance of the aluminium alloys.
