“…This intermixing leads to bonding between the coating and the substrate. The orientation of the grain and boundaries between the smaller BCC grains of the substrate and the larger FCC grains of the coating is also a strong evidence of the bonding of the friction surfaced coatings [14]. However, crack formation at the interface of the coating and the substrate of a single layer in Fig.…”

“…In most of the coatings, hardness measurement reveals an increase in hardness near the surface of the coating due to significant grain refinement. Vilaca et.al [14] observed that the grain refinement is a result of nucleation and the growth of new grains that occurs due to high strain rate characteristics of the solid state processing. Fig.…”

SummaryNowadays friction surfacing (FS) has become a popular solid state surface coating technology suitable for a range of substrates. The technology has the ability to produce coatings with marginal dilution and good metallurgical bonding. The present study has aimed at producing a single-track and a three-track overlapping coatings on high-speed steel substrates using an AISI 316 consumable rod. Microhardness of coatings was examined by a Vickers micro hardness tester. Coatings of all the friction surfaced samples in as-deposited condition showed significant hardness. The infrared thermography showed that the peak temperature achieved by the AISI 316 coating was about 1020 ͦ C. The coatings, thus attained, were further analysed for their microstructural features and interfacial characteristics by using FE-SEM. The EDX analysis showed the presence of nickel, chromium and oxygen, which indicates the formation of oxide compounds. The formation of AISI 316 deposits on the HSS substrate and the effect of coating overlapping are discussed in this article.

“…The FS tests involved an initial stage in which the rotating consumable rod was plunged into the steel plate at a 2.5 mm/min feed rate until the rod was consumed in 1 mm. This was performed to heat the rod/plate interface and initiate viscoplastic flow at the rod tip, which led to the characteristic flash formation [12]. Then, the substrate was moved relative to the rod following a 0.5 ratio between total vertical (downwards) and horizontal displacement, for pre-defined forward speeds of 250, 400, and 600 mm/min.…”

“…From an application perspective, various different substrate/coatings have been pursued by FS, including stainless steel, tool steel, alloy steel, and Al-alloy and Ni-alloy coatings, mainly on carbon steel substrates [1]. The development of stainless steel, Ni-alloy, and Ti-alloy coatings on carbon steel is interesting for structural elements operating in reactive environments and investigations have been directed to both metallurgical/mechanical behavior of the FS coatings [7,[9][10][11][12] as well as corrosion resistance [13,14]. Tool steel coatings have been pursued because of their industrial relevance [15].…”

Friction surfacing is a solid-state joining process that can be applied to develop similar or dissimilar combinations/joining partners that exhibit sound mechanical properties while avoiding some of the problems associated with the conventional deposition methods in which fusion is involved. Currently, however, the friction surfacing process is carried out in specialized equipment which do not yet have widespread industrial use. With the objective of exploring new application possibilities, in the present work, the viability of employing the friction surfacing process in a machining center with computerized numerical control was investigated. To this end, the deposition of 6351 Al-alloy coatings on a 1020 carbon steel substrate was pursued. After preliminary tests for determining viable deposition parameters, the influence of process variables (rod diameter, rotation, and forward speed) on coating geometry and mechanical properties was investigated using design of experiments methodology. Adhesion of the coatings was evaluated by applying a simple push-off test. The surface finish of the substrate plate was found to influence heat generation during the deposition process and impacted coating deposition. The results demonstrated that, although parameters must be carefully tuned, the process can be feasibly applied under the experimental conditions investigated, and a maximum push-off force value of 4250 N could be achieved.

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.
