“…Vickers microhardness profile across the coating/substrate interface (Rafi et al, 2011c). Rao et al (2012a) reported some mechanical effects on the carbide distribution in the FS of Stellite6 over mild steel, such as their fragmentation into finer particles as a consequence of the bulk plastic deformation of the consumable rod. Kramer de Macedo et al (2010) studied the viability of recovering components in ABNT 1070 high carbon steel using consumable rods of ABNT 8620, ABNT 4140 and austenitic stainless steel AISI 310.…”

“…Considering other solid state cladding processes, such as, explosive cladding or roll bonding, FS can be seen as a more versatile alternative for localized treatments. Rao et al (2012a) compared the microstructure and hardness of Stellite6 coatings produced by FS with those produced by fusion based processes, such as, gas tungsten arc and plasma transferred arc welding. Friction surfaced coatings presented a finer microstructure and relatively higher hardness values (Fig.…”

Friction surfacing (FS) is a solid state technology with increasing applications in the context of localized surface engineering. FS has been investigated mainly for producing fine grained coatings, which exhibit superior wear and corrosion properties. Since no bulk melting takes place, this process allows the dissimilar joining of materials that would be otherwise incompatible or difficult to deposit by fusion based methods. Several studies also emphasize its energy efficiency and low environmental impact as key advantages when compared with other alternative technologies. Main applications include the repair of worn or damaged surfaces through building up or crack sealing. It has also been applied to enhance surface properties at specific areas in the manufacturing of parts and tools. A wide range of materials combinations has been deposited by FS, mainly alloy and stainless steels. Aluminium, magnesium and titanium alloys have also been investigated, including the production of metal matrix composites. Starting with a brief introduction, this review presents a detailed description of the thermo-mechanical and microstructural transformations, as well as, process modelling approaches. The material combinations investigated so far and the effect of process parameters are also addressed. An overview of the main technologic and equipment 6.2. Pre-heating or cooling concepts .

“…The Friction Surfacing (FS) technique has become an essential form of surface engineering, since the coatings deposited by this process may be used for extending the service life of various components by repairing worn parts and improving wear resistance and anticorrosion properties 1,2 . The FS concept was first patented as a metal coating process by Klopstock and Neelands, in 1941 3 .…”

Titanium Grade 1 was deposited on Ti-6Al-4V, 2 mm thickness, by Friction Surfacing. The process parameters were rotational speed, deposition speed and consumption rate. Only the rotational speed was varied in order to evaluate the influence of this parameter on the coatings generated. The applicability of the process has been described for a large number of materials, although the depositions of titanium alloys are still not widely studied. The objective is to investigate the effects of the rotational speed on the coatings' geometry and microstructural evolution. This investigation has shown that Titanium Grade 1 coatings can be deposited onto a Ti-6Al-4V by Friction Surfacing depending on the rotational speed. The coatings' surface homogeneity was influenced by the rotational speed, being inhomogeneous for the lowest speed. The coatings' thickness and width increased with enhancing this speed. The heat affected zone in the substrate corresponded to the complete thickness under the depositions.
