Purpose: Main purpose of the paper is results share of AlSi9Cu and AlSi9Cu4 cast aluminium alloys treatment investigation. Processing was performed using CAE-PVD method in order to obtain gradient coatings. Design/methodology/approach: CAE-PVD method was used to obtain gradient coatings on AlSi9Cu and AlSi9Cu4 cast aluminium alloys after heat treatment. Investigation of resulting material was performed using SEM, TEM, GDOS, ball-on-disk wear resistance test and microhardness test. Findings: The investigations presented in this paper reveal that it was possible to successfully deposit Cr/CrN/CrN, Cr/CrN/TiN, and Ti/Ti(C,N)/(Ti,Al)N nano-crystalline coatings on Al-Si-Cu aluminium substrate using CAE-PVD method. Investigations of the coatings reveal a microstructure that adhere tightly to the aluminium substrate without any visible delamination but with visible transition zone between the investigated layers and the substrate material. Research limitations/implications: There is need for further research activity in field of nanocomposite films and coatings that should concentrate on following problems: controlled grain size of coatings/films, development of hybrid coatings with unique physical and functional properties, e.g. nanophase biomaterials. Practical implications: Better understanding of mechanisms that proceed during CAE-PVD treatment of AlSi9Cu and AlSi9Cu4 cast aluminium alloys. Creation of material, that, thanks to the treatment, can be coated with layer characterized by gradient chemical composition with unique physical and functional properties (e.g. higher microhardness or corrosion resistance, lower friction coefficient, etc.) that can be successfully applied within aerospace and automotive industry or even on field of biomedical applications with use of nanophase biomaterials or nano-crystalline amorphous materials. Originality/value: Cr/CrN/CrN, Cr/CrN/TiN, and Ti/Ti(C,N)/(Ti,Al)N nano-crystalline coatings were deposited on Al-Si-Cu aluminium substrate. They are characterized by visible transition zone (gradient) between the investigated layers and the substrate material.
