Friction surfacing of aluminum to steel: Influence of different substrate surface topographies Open
In the present study, AA6082 aluminium is deposited onto AISI 4140 steel substrates via friction surfacing (FS). Aiming to understand the influence of substrate surface for the bonding mechanism during the plasticising as well as the depos…

Precipitation Evolution in the Heat‐Affected Zone and Coating Material of AA2024 Processed by Friction Surfacing Open
Herein, self‐mating coating depositions are generated from Al–Cu–Mg alloy AA2024 by using the solid‐state joining method, friction surfacing (FS). The precipitation evolution in the heat‐affected zone (HAZ) of the substrate material and in…

Effects of Microstructure Modification by Friction Surfacing on Wear Behavior of Al Alloys with Different Si Contents Open
In this work, Al alloys with 6.6%, 10.4%, and 14.6% Si were deposited as thick coatings by Friction Surfacing (FS), resulting in grain refinement and spheroidization of needle-shaped eutectic Si phase. Lubricated sliding wear tests were pe…

Alloy Microstructure Dictates Corrosion Modes in THA Modular Junctions Open
Implant failure resulting from corrosion processes within modular junctions is a major concern in THA. Our results suggest that implant alloy microstructure is not sufficiently standardized and may also dictate specific corrosion modes and…
