“…The microstructures of the consumable rod in the flash (region A) and the heat-affected region (region B) are presented in Figure 16. Similar to findings by Vilaça et al [20], the grain structure in the flash was finer and more uniform than in region B, since the flash materials experienced significant plastic deformation. During the FS process, the rod was subjected to substantial plastic deformation.…”

In this work, friction surfacing (FS) of AA5083 on a DH36 steel substrate was experimentally studied. The process parameters such as rotation speed, travel speed and feed rate are of great significance to the success of the FS process. Seven friction surfaced plates with different combinations of parameters were examined. Optical microscopy, SEM and EDS were used to analyse the characteristics of the microstructure and composition of the interface between the surface and the substrate. The results show that the deposition surface quality decreased as the feed rate, travel speed and axial force increased. However, the bond strength increased with higher feed rate, higher rotation speed and lower travel speed. Elemental diffusion of Fe to AA5083 was established, and the intermetallic compound FeAl3 was produced in the interface.

“…During channelling, rotating profiled pin generates an upward force, due to which parting of the plasticized material occurs around the pin from the plasticized material. As the plasticized material is shifted upwards through the rotation of the pin and it is deposited on the top of the nugget beneath the shoulder surface a channel is formed [48].…”

Friction stir based processes are solid state processes which significantly contribute to joining/processing of materials and surface property enhancement. It replaces conventional joining/processing techniques owing to their unique features such as reduced distortion, reduced porosity defect, reduced heat affected zone (HAZ), no requirement of shielding gas, eco-friendly etc. Also, It enhances the mechanical and metallurgical properties of the material namely grain refinement, microstructure modification, homogenization, corrosion, fatigue, wear and hardness, which are laborious to attain in fusion welding. This review approaches the detailed study on friction stir-based processes, starting from friction stir welding and their applications in present scenario.

“…Puli and Janaki Ram 7 proposed to machine the unbonded edges by up to 3 mm (1.5 mm each side) before performing the next deposition. In addition, the deposition of multiple successive layers increases the thickness of the coating surface, thus increasing the possibility of producing profiles with desired geometries after machining processes 8 .…”

Assessment of Process Parameters by Friction Surfacing on the Double Layer Deposition

The friction surfacing process of two deposited layers on two deposition surface conditions, i.e., a smooth interface and a rough interface, was investigated. The control parameter of the deposition process was the rod feed rate with the use of a conventional milling machine. Analyzes of the surface characterization and microstructural characterization along the produced deposits were performed. The interface strength of the substrate/deposit1 (smooth) and deposit1/deposit2 (rough) was evaluated by bending tests and the micro-hardness profile along the transverse section of the substrate/deposit1 and deposit1/deposit2. The bending tests revealed the presence of smalls delaminations with no evidence of fracture at the rough deposit1/deposit2 interface (D1/D2) with less predominance in the deposition condition 3B. This suggests that the combination of the travel speed of 5.5 mm/s and an increase in the consumable rod feed rate of (≥5.5 mm/s) increases the adhesive strength of the two produced interfaces.
