“…The evaluation of the coating/substrate interface's strength was conducted using the push-off test (POT). 31 The SPT was conducted per the method described by Guduru et al 32 The measurement process of the coating/substrate interface strength and shear strength was repeated three times in each condition to ensure the reproducibility of the results. Additionally, an assessment of hardness changes was performed using the Vickers microhardness measurement method, following the ASTM E384 standard, employing a 100 g load for a duration of 10 s. To further evaluate the wear resistance of the coating, cylindrical samples with a diameter of 6 mm, oriented perpendicular to the coating, were meticulously prepared.…”

In this study, we investigated the impact of ageing heat treatment following friction surfacing of a solid solution-treated Al-16Si alloy on coating geometry, microstructure, and wear resistance. We employed a simulation using the smoothed-particle hydrodynamics (SPH) method alongside experimental analysis. The simulation results revealed that as the rotational speed increased from 600 to 1000 rpm, the coating efficiency decreased significantly from 31.2 to 13.1%. When comparing the coating to the substrate and the consumable rod, it was seen that after ageing heat treatment, the wear rate of the coating made at a rotational speed of 600 rpm dropped by a lot, by 70% compared to the substrate and by 53% compared to the consumable rod.

“…Since from the development of friction surfacing process it was used to coating the substrate with the materials only available in the consolidated form [9][10][11]. However, the coating of ceramic and carbonaceous materials (such as SiC, TiC, Al 2 O 3 , WC, TiB 2 , MoS 2 , Graphite etc) which have proved to upsurge the tribological performance of the aluminium alloy through composite fabrication (with other liquid metallurgy, powder metallurgy routes etc.)…”

In present study, a strategy for mechanical exfoliation of graphite to a few layered graphene (FLG) coupled with its mechanical infusion onto aluminium (Al6061) substrate through a solid-state friction surfacing (FS) methodology is developed and documented. Here, a graphite-rich and expendable FS tool fabricated through conventional powder metallurgy is used as a source of graphite. Later on, this expendable tool is utilized for impregnating graphite on the aluminium alloy surface through FS. The high frictional shear stress during FS results in the exfoliation of graphite to FLG which is confirmed by the characteristic wrinkled morphology through FE-SEM studies. Experimental results revealed successful impregnation of FLG flakes up to ∼165 μm depth on the surface of aluminium matrix. The effect of graphite flake size (60 mesh (max. 250 μm) and 325 mesh (max. 44 μm)) on specific wear rate and its ability to mechanically exfoliate into a FLG structure is also analysed. Dynamic recrystallization due to plastic deformation during FS results in∼90% grain size reduction relative to the as-received aluminium alloy (reference Al). Excellent interfacial bonding with mechanical intercalation between graphite flake and aluminium matrix is also observed through TEM studies. Intermetallic phase such as Al 4 C 3 is observed at the Al/graphite interface with larger flake size. The tribological properties are significantly improved with the graphite reinforcement leading to the decrease in coefficient of friction by ∼12.5 and 26.7% with graphite of 250 (FS250) and 44 μm (FS44) flake size respectively as compared to the reference Al. The least specific wear rate is observed for FS44 which is about ∼53.4 % and∼28.57 % less than the wear rate of reference Al and FS250, respectively. The microhardness, nano-hardness and XRD studies further corroborate the results.

Friction surfacing finds its application in areas which require joining of dissimilar metals with superior wear property. The current work investigates the solid‐state coating of Alloy 36 over ductile cast iron (SG Iron) by friction surfacing process. The effect of process factors on the actual geometry of the coating was investigated through testing and a desirability‐based technique. Spindle speed, axial force, and table traverse speed were the three most important variables for bonding fidelity. Analysis of variance was used to examine how the input parameters affected the output parameters. Experimental findings are validated using artificial neural networks and response surface methodology which are then used to predict how the system will respond to various operating scenarios. The research demonstrates that speed, rather than force or traverse action, has a more substantial effect on both materials. The response surface methodology statistician approach was utilized to identify the most important factors influencing the process parameters. As a result, the load is determined as the most crucial component that impacts bonding to the substrate. According to the data, the output parameters have the most impact on lowering the bonding geometry.
