Friction Surfacing Deposition by Consumable Tools
Abstract Friction surfacing is a new variation of friction stir processing for surface property modification of metallic substrates. There is an increasing body of literature about friction surfacing by deposition of metal from a consumable tool to a solid substrate. Friction surfacing has many potential applications in joining, coating for corrosion resistance, and repair of degraded components. This article presents a review of the basic principles and latest research organized by processing techniques and variations, thermomechanical transfer and deposition of material, and finally metallurgical, mechanical, and chemical properties of the resulting deposition. Different friction surfacing processes are reviewed of novel tool–substrate configurations for material deposition for noncoating purposes like keyhole filling and joining dissimilar materials. Possible future topics of study for this area are discussed, which include deeper understanding of material transfer through metallurgy, FEM, and scale up of the technique for practical application.

Friction surfacing is a solid-state metal deposition technique suitable for a wide range of metallic materials. This technique results in coatings on surfaces for joining purposes or surface modification applications such as wear and corrosion performance improvements. In this study, a novel approach in friction surfacing is utilized in which the consumable tool deposits material from its side instead of the end of the tool, which has been employed in conventional friction surfacing. Frictional heat enables plastic deformation, which results in the depositing of the consumable material on the substrate surface. The process is carried out at temperatures below the melting point of the consumable material, resulting in a solid-state deposition process. In the current study, scanning electron microscopy and energy dispersive spectroscopy have been employed for the characterization of the interfaces and coatings. The results of this study exhibited that there is no elemental diffusion between the tool and substrate materials at the interface, showing that the process temperature was low enough to prevent plasticizing of the substrate surface.
Friction Surfacing From Radial Surface of A6063 Aluminum Alloy Consumable Tool Onto A36 Carbon SteelFriction surfacing is an advanced technique to create solid-state deposition of wide range of materials onto a similar or dissimilar material substrate. This paper describes the study of a novel method to deposit material onto a substrate by friction surfacing. In the friction surfacing technique, the heat is generated entirely by friction. This metallic deposition technique consists of a rotating consumable tool that rubs against the surface of the substrate, and due to the frictional heat and forging generated between the tool and substrate, material is deposited onto the substrate. The material transferred from the consumable tool to the substrate occurs from the side of the tool, while in the conventional friction surfacing method, the material transfer happens from the end of the tool. In this investigation, the single and double-pass deposition of A6063 aluminum alloy onto an A36 carbon steel substrate was successfully carried out. To study the influence of the process parameters on the friction depositions, the substrate was divided into three sections, while the applying forces were varied in each section. Process parameters such as tool rotational speeds, table traverse speeds and normal force were experimented. A customized JET JMD-18 milling machine was used to carry outmore »
A Novel Approach to Friction Surfacing: Experimental Analysis of Deposition from Radial Surface of a Consumable ToolThe friction surfacing technique is an advanced method for creating coatings of various materials onto the surface of a similar or dissimilar material substrate. In this method, there is no external source of heat energy, and all the heat energy required in this method is generated by friction. In this paper, a novel method of friction surfacing from the side of the consumable tool is introduced. The most significant difference in this technique is that material transfer will occur from the radial surface of the consumable tool as opposed to the end of the tool as in conventional friction surfacing. In lateral friction surfacing, the side of the rotating consumable tool is pressed against the substrate surface, which generates frictional heating and shear forces at the interface between tool and substrate. A layer of tool material is transferred from the consumable rod to the substrate surface as the tool moves across. In this study, 6063 aluminum alloy and AISI 1018 carbon steel are used as the materials of consumable tool and substrate, respectively. The impact of process factors, surface roughness values, tool mass loss, and deposition thickness are discussed in detail. The experimental results of this study reveal that lateralmore »
Friction surfacing technique is a thermo-mechanical approach for metallic deposition, suitable for a broad range of materials and applications. Friction surfacing can be employed for various industrial purposes such as coating, welding, repairing defective parts, surface hardening, and improving corrosion performance. In this technique, frictional heat generated at the interface of the consumable tool and substrate results in a severe plastic deformation at the end of the rod, enabling the deposition of a consumable material on the substrate surface. In this investigation, a novel method in friction surfacing, lateral friction surfacing, is employed to deposit the aluminum coatings. In this novel approach, the side of the consumable tool is pressed against the surface of the substrate, and the material transfer happens from the lateral surface of the tool. This technique provides extremely thin and smooth deposits, which are more consistent compared to the conventional approach of friction surfacing. Moreover, this technique enables fabricating of deposits in lower temperatures, lessening the thermal impacts on the microstructures and mechanical properties of the deposits. In this investigation plates of 1018 mild steel were partially coated with various aluminum alloys and corroded in an accelerated corrosion test chamber. The corrosion performance of the partiallymore »
