“…Copper-based functional layers are particularly well suited for low-speed and heavy-duty applications in wind turbines owing to their excellent tribological characteristics, good thermal conductivity, high load-bearing capacity, and high fatigue strength. [3][4][5] In light of the advances in lead-free materials, the antifriction layer fabricated by adding graphite, Bi, FeS, and other lubrication components to an Sn bronze matrix is regarded as the ideal bearing material. [6,7] However, austenite transformation occurs in steel near the liquid-solid compound interface of Sn bronze and low-carbon steel.…”

To address the challenges of liquid metal embrittlement (LME) cracks and low bonding strength at the Sn bronze/steel liquid–solid compound interface, an innovative Sn bronze/Al bronze/steel laminated composite is fabricated using a wire arc additive manufacturing (WAAM) process, which involved introducing an Al bronze interlayer. The microstructure of interlayer and its related interfaces, as well as the mechanical properties of the composites, are investigated. Results show that the microstructure of Al bronze is mainly composed of α‐Cu and β‐Cu3Al. An interdiffused layer with a maximum thickness of 5 μm exists at the Al bronze/steel interface, which plays an important role in interface adaptation. The Sn bronze/Al bronze interface possesses a 30 μm α(Cu–Al–Fe) transition layer, and the continuous transition of α + β → α(Cu–Al–Fe) → α(Cu–Sn) from the base material to the clad layer is realized. No LME cracks are found in the steel after the Al bronze and Sn bronze deposition. The Al bronze/steel and Sn bronze/Al bronze interfaces exhibit strong bonding strengths of 395 and 361 MPa, respectively.

Due to their superior mechanical properties, formability, corrosion resistance, and lightweight nature, 6xxx series aluminum (Al) alloys are considered as a promising structural material. Nevertheless, the successful application of these materials depends on their response to the external environment. Recently, designers considered the surface properties an equally important aspect of the component design. Due to this concern, these alloys are subjected to varieties of surface modification methodologies. Many methodologies are explored to modify the 6xxx series Al alloys surfaces effectively. These methods are anodizing, plasma electrolytic oxidation (PEO), cladding, friction stir processing, friction surfacing, melting, alloying, and resolidification using high energy beams, etc. This review work discusses some of these methods, recent research activities on them, important process variables, and their role on the final properties of the surfaces.
