“…During the tests, the rotation speed, normal load, and total sliding distance were adjusted as 0.08 m/s (150 rpm), 20 N, and 150 m, respectively. A setup with a block-on-cylinder configuration mounted inside a heating chamber was used for HT tribology tests at 450 °C to simulate aluminum extrusion conditions [ 25 , 26 , 27 ]. A cylindrical billet of A6080 (ϕ 100 mm × 30 mm) served as a counterpart using a normal force of 70 N, a sliding speed of 0.27 m/s (53 rpm), and a total sliding distance of 2000 m. The configurations for the tribology tests are shown schematically in Figure 1 .…”

In this study, heat-treated and multisurface engineered DIN 1.2367 tool steel was subjected to room and elevated temperature wear tests, and the effect of nitriding on its tribological behavior was investigated. CrN, AlTiN, and CrN/AlTiN coatings with a total thickness of 2 µm were obtained by arc cathodic physical vapor deposition on conventional heat-treated and gas-nitrided steels. The white layer formed during nitriding was removed, and a diffusion layer (100 µm) was achieved in the cross section of the steel having a tempered martensitic matrix. The highest surface hardness was attained with an integral coating (CrN/AlTiN), and surface hardness increased even more after nitriding due to the formation of a multicomponent ceramic layer on top of the diffusion layer. The room temperature wear tests performed against an alumina counterpart revealed that (i) CrN/AlTiN-coated steel had the highest friction coefficient of 0.26, which further increased to 0.33 by nitriding due to the increase in shear strength, and that (ii) with increasing surface hardness, the specific wear rates (W) of the heat-treated and coated steels could be ranked as follows: WCrN/AlTiN < WAlTiN < WCrN. The wear rates decreased when nitriding was carried out prior to coating. In order to simulate the aluminum extrusion conditions, hot wear behavior of the surfaces against AA6080 alloy at 450 °C was investigated. The hot wear tests revealed that (i) high friction coefficients were reached due to the adhesive characteristic of aluminum to the surfaces, (ii) the nitrided and CrN/AlTiN-coated sample exhibited the lowest wear rate among all studied surfaces, and (iii) the film damage on the worn surfaces mostly occurred in the form of droplet delamination.

“…For resistance spot welding, a water-cooled copper electrode with a contact diameter of 4 mm was used in a resistance spot welding machine, with parameters ranging from 5 kA to 50 kA based on literature recommendations. Friction stir spot welding (FSSW) of this alloy was performed on a CNC vertical milling machine using AISI 1050 steel as the tooling material and using specific parameters [11]. AA1050 aluminum strip used a heated flat die driven by a hydraulic flat ram for vertical compression.…”

The study explores the innovative friction-assisted solid-state lap seam welding method, showcasing its success in creating multi-metal, multi-layered friction seam welds with diverse materials. Metallurgical bonding achieved through dynamic recrystallization at the seam weld interface resulted in enhanced tensile strength compared to base metals. The research emphasizes the method's applicability in the aeronautic industry, addressing challenges in joining advanced materials. The environmental advantages of Friction Stir Welding (FSW) over conventional arc welding are highlighted, offering valuable insights into its superior mechanical properties. The findings suggest promising avenues for advancing welding techniques, urging further research for refining metallurgical bonding mechanisms and optimizing process parameters for diverse material combinations.
