“…It is reported that the deposition efficiency is a function of energy input for a fixed volume and affects the deposited material. The deposition geometry is also reported as a function of the process parameters and temperature evolution during friction surfacing [109,110]. From the direction of friction surfacing, 6xxx series alloys as the tool material are more explored than 6xxx series alloys as the substrate material [109][110][111][112][113].…”

Due to their superior mechanical properties, formability, corrosion resistance, and lightweight nature, 6xxx series aluminum (Al) alloys are considered as a promising structural material. Nevertheless, the successful application of these materials depends on their response to the external environment. Recently, designers considered the surface properties an equally important aspect of the component design. Due to this concern, these alloys are subjected to varieties of surface modification methodologies. Many methodologies are explored to modify the 6xxx series Al alloys surfaces effectively. These methods are anodizing, plasma electrolytic oxidation (PEO), cladding, friction stir processing, friction surfacing, melting, alloying, and resolidification using high energy beams, etc. This review work discusses some of these methods, recent research activities on them, important process variables, and their role on the final properties of the surfaces.

“…Fitseva et al [11] analyzed the deposition behavior and process characteristics of titanium alloys with various rotational speeds and found increasing the rotational speed causing an increase in the coating width and thickness and also increasing the deposition efficiency up to 39%. Krohn et al [12] investigated the influence of external cooling on friction surfaced between aluminium alloys and found the intensity and location of cooling affecting process characteristics and modifying the coating geometry. In their experimental work, Stegmueller et al [13] made a study of the inductive heating effect between stainless steel and aluminium substrate and found an increase in the rotational speed causing a decrease in the coating mass and thickness but an increase in flash masses of the consumable rod.…”

In the present work, an experimental exploration was made to study the bond strength on solid-state coating of aluminum 6063 over EN24 carbon steel by friction surfacing process using different mechtrode diameter. Friction surfacing was carried out by different combinations of elemental process parameters with different mechtrode rods of 12 mm, 18 mm, and 24 mm in diameters. The result showed that the applied axial force and rotational speed has a strong correlation on diameter of mechtrode for obtaining a successful coating during the process. A non-contact infrared (NC-IR) thermometer provided the temperature profile, and the highest temperatures recorded were 358°C, 389°C, and 422°C for the 12 mm, 18 mm, and 24 mm rod diameters, respectively. The mechanical strength of the successful coating was analyzed using the Vickers microhardness and bending tests. The result exhibited that the coating sample obtained by the 18 mm rod diameter gave higher hardness value (142 HV at the interface) and bending strength (481 MPa at 120° bend angle) compared to coating samples obtained from the 12 mm and 24 mm rod diameters. The coating was analyzed using field emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray analysis (EDAX) techniques to know the feature of microstructure and intermetallic bonding. The result revealed the formation of better martensite attributes and more oxide compounds at the interface of sample made by the 18 mm rod diameter, indicating adequate molecular interlocking between aluminium and iron particles.
