“…This is an unexpected outcome considering that a number of authors state that an increase in micro-hardness is one of the primary benefits of FSP [44,45]. The lack of any hardness increase identified in the present study has also been reported by Chen et al [46] whilst investigating the effect of FSP on the mechanical properties of AA5083.…”

This study forms an initial investigation into the development of SprayStir, an innovative processing technique for generating erosion resistant surface layers on a chosen substrate material. Tungsten carbide – cobalt chromium, chromium carbide – nickel chromium and aluminium oxide coatings were successfully cold spray deposited on AA5083 grade aluminium. In order to improve the deposition efficiency of the cold spray process, coatings were co-deposited with powdered AA5083 using a twin powder feed system that resulted in thick (>300 µm) composite coatings. The deposited coatings were subsequently friction stir processed to embed the particles in the substrate in order to generate a metal matrix composite (MMC) surface layer. The primary aim of this investigation was to examine the erosion performance of the SprayStirred surfaces and demonstrate the benefits of this novel process as a surface engineering technique. Volumetric analysis of the SprayStirred surfaces highlighted a drop of approx. 40% in the level of material loss when compared with the cold spray deposited coating prior to friction stir processing. Micro-hardness testing revealed that in the case of WC-CoCr reinforced coating, the hardness of the SprayStirred material exhibits an increase of approx. 540% over the unaltered substrate and 120% over the as-deposited composite coating. Microstructural examination demonstrated that the increase in the hardness of the MMC aligns with the improved dispersion of reinforcing particles throughout the aluminium matrix

“…In this study, the difference value between the cumulative strains at different rotational speeds is close to 2. Studies (Fan et al, 2012;Xu et al, 2017;Chen et al, 2016b) indicated that each increase of 1 in the accumulation of strain during SPD has a significant effect on the microstructure of the material. Especially when the grain size is large, the influence of the strain is more significant.…”

“…Increasing pass times and changing direction of tool rotation between the two passes can improve the plastic deformation of the processed materials. Hence, the grain refinement and improvement in materials properties are more significant [28]. Multi-pass FSP has been widely used in the production of composites.…”

Friction stir processing (FSP) is a novel solid-phase processing technique that is derived from friction stir welding (FSW). The microstructure of the base metal can be modified with the friction heat and stir function during processing. It can be used to fabricate surface composites and in situ composites by adding reinforced particles into the metal matrix via FSP. Friction stir processing can significantly improve the hardness, wear resistance, ductility, etc., while preventing defects caused by material melting. It is an ideal material processing technology and has good prospects in the field of superplastic materials and for the preparation of metal matrix composites. This paper reviews research developments into the principle, process, and applications of FSP technology as well as its future research directions and development prospects.
