The Stationary Shoulder Friction Stir Welding (SS-FSW) technique benefits from reduced heat input, improved mechanical properties and surface finish of the weld, avoiding the need for post weld processing. Coatings on the tool probe and the shoulder for welding of aggressive Aluminium alloys have rarely been successful. Such coatings must be well adherent and inert. In this study, coated tools were used for SS-FSW of AA6082-T6 alloy. Performance of a nanoscale multilayer TiAlN/VN coating deposited by High Power Impulse Magnetron Sputtering (HIPIMS) technology was compared with amorphous Diamond Like Carbon (a-C:H) by Plasma Assisted Chemical Vapour Deposition (PACVD), AlTiN deposited by arc evaporation and TiBCN along with TiB2 produced by Chemical Vapour Deposition (CVD) methods. The TiAlN/VN coating was found to have low affinity to aluminium, acceptable coefficient of friction and provided excellent weld quality by inhibiting intermixing between the tool and workpiece materials resulting in a significant reduction in tool wear.

HFACVD (Hot Filament Assisted Chemical Vapour Deposition) is a typical technology which permits the coating of soft materials with hard or super hard layers which lead to ultra wear resistant tools. Typical tools obtained with this technology are based on a diamond layer. Unfortunately, these tools are not suitable for machining of ferrous alloys due to chemical issues, yet their use is very promising in the machining of composites based on aluminium matrix and reinforced with alumina or silicon carbide. In this paper HFACVD diamond coated, WC and PCD tools are used in turning of Al2O3/Al composites until they are completely worn out. The results show that the diamond tools can be competitive with both the WC and PCD ones in the industrial applications.
