“…The authors reported a decrease of corrosion current after artificially ageing the deposited material. Similar observations were stated by Pirhayati et al 14 for FS deposited AA6061. The specific literature available on the corrosion behavior of FS deposited material is not very extensive, but related materials’ processing approaches, which are also based on friction and plastic deformation, like friction stir welding (FSW), show a larger amount of research studies with regard to corrosion 15 .…”

Friction surfacing (FS) is a solid-state coating technology for metallic materials, where the deposition of a consumable material on a substrate is enabled via friction and plastic deformation. The deposited layer material commonly presents a significantly refined microstructure, where corrosion could be an issue due to this grain refinement within the layer deposited, possibly creating micro galvanic pairs. The present work investigates the corrosion behavior of the FS deposited material as well as stud base material and substrate using cyclic polarization tests and open circuit potential (OCP) monitoring. Comparing the FS deposited material and the respective consumable stud base material (both AA5083), the grain size is correlated with the results from the corrosion tests, where the deposited material shows more equiaxed and refined grains in comparison to the stud base material. The cyclic potentiostatic polarization tests showed that the stud base material is more resistant to pitting nucleation presenting smaller pits and a lower amount of pits compared to deposited material and substrate. As a complement to OCP test, the stud base material is also more stable on a chloride solution compared to the substrate and the deposited material.

In this paper, the evolution of the microstructure, mechanical properties, and intergranular corrosion (IGC) resistance of an Al-Mg-Si-Ag alloy is systematically investigated. For the as-cast alloy, the microstructure consists of the Mg2Si phase and Mg32(Al, Ag)49 phase. In the isothermal aging process, the novel alloy presents a significant age hardening effect. The ultimate tensile strength (UTS) and yield strength (YS) of the peak-aged alloy are 342 MPa and 231 MPa, respectively, which are 53 MPa and 84 MPa higher than that of the as-quenched alloy. The main strengthening phase at the peak-aged stage of the alloy is the MgAg phase, which has a body-centered cubic structure with a lattice constant of a = 0.33 nm. In addition, the IGC resistance of the peak-aged alloy is worse than that of other aged alloys. The corresponding microstructure of GBPs of the peak-aged alloy is more consecutive, and this is the main reason for the deterioration of IGC resistance of the alloy.

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.
