“…SEM-EDS (JSM-7900F) was applied to examine the change in surface morphology as well as the elemental composition presented on the alloy surface after alloy samples were immersed in NaCl solution in the absence and presence of the inhibitor [ 33 , 34 ]. Furthermore, FT-IR (Nicolet iS50, wave numbers region from 4000 cm −1 to 400 cm −1 ) and XPS (ESCALAB250) techniques were used to study the chemical composition and formation mechanism of the product layer on the surface of these alloy samples [ 35 ].…”

In this work, a cerium/tetraethylenepentamine dithiocarbamate complex was synthesized and evaluated for the corrosion inhibition capability on an AA2024-T3 Al alloy in a 3.5% NaCl medium. The synthesized compounds were characterized via spectroscopic techniques. The corrosion inhibition behaviour of the complex was elucidated by electrochemical measurements and surface analysis techniques. Based on electrochemical test results, the corrosion inhibition efficiency of the complex increases with the immersion time of aluminium alloy in the test solution. The corrosion inhibition reaches 96.80% when the aluminium is immersed in a 3.5% NaCl solution containing a corrosion inhibitor for 120 h. The potentiodynamic polarization test results show that the complex acts as a mixed-type corrosion inhibitor and the passive range is widened. The surface analysis methods reveal that the corrosion inhibition ability of the complex originated from the formation of a protective layer on the Al surface. This film is created from the physisorption and chemisorption of cerium ions and organic parts simultaneously released from the complex molecules.

“…Including the metal substrates and the Zn coatings, the interfacial intermetallic compound (IMC) layer are essential for bonding between aluminium and steel substrate in RSW joint [2,7,10]. The IMC layer tend to form at the interface of dissimilar metals via atomic diffusion during welding [13][14][15]. The thickness of the IMC layer strongly affects the strength and fracture modes of aluminium/steel RSW joints.…”

Interfacial intermetallic compound (IMC) layer is critical during realizing the galvanic corrosion mechanism and strength degradation of aluminium/steel resistance spot welding (RSW) joints. The effect of IMC layer on the corrosion behaviour of RSW joint between 5182 aluminium alloy and galvanized DP780 dual-phase steel was investigated by immersion corrosion method and electrochemical method. Results demonstrated localized corrosion around Fe-rich phase particles on aluminium nugget and preferential corrosion at the interface front near IMC layer. The IMC layer had the highest open circuit potential value of -0.569 V and low corrosion current density among the investigated nugget and substrates. The potential difference (0.184 V) between the cathodic IMC layer and large area of anodic aluminium nugget was responsible for the preferential initiation of localized corrosion at the interface front near the IMC layer.

“…Along with the diffusion evidence in other areas of the contact, they noticed tiny flaws around the welding interface. According to SafaraliFeleh Shargh et al [29], raising the temperature and duration of the process of heat treatment at the specimen interfaces tends to decrease the energy stored during explosive welding, the distinction in the concentration of aluminium when compared to steel in the interface layer, the rate of corrosion (current density), and the electrical charge transfer. In order to investigate dissimilar welding between H21 steel and copper alloy of 1015, Sahin et al [30] coupled friction welding with a heat transmission mechanism.…”

By using fusion welding to weld AISI 304 austenitic stainless steel (ASS) and commercial copper, the creation of brittle intermetallic in the weld region that compromises the strength of the joints is the primary challenge. However, friction welding is a suitable method for joining these two materials because no obvious defects are produced at the joints. The joint strength is significantly influenced by the friction-welding-process variables including the pressure of friction, pressure of forging, time of friction, and time of forging. Throughout this study, a central composite factorial design-based empirical relationship-building effort was carried out to determine the tensile strengths of friction-welded AISI 304 austenitic stainless steels (ASS) and commercial copper alloys dissimilar joints from the process variables. The process conditions were optimized employing response surface methods in order to attain the joint’s optimum tensile strength. This research revealed that the greatest tensile strength of the joint created with the friction pressure of 60 MPa, forging pressure of 60 MPa, friction duration of 4 s, and forging time of 4 s, correspondingly, was 489 MPa. As a result, the intermetallic formation at the interface could be identified.
