Aluminum Alloy Powder

Purpose This study aims to investigate the effect of coatings prepared by the addition of copper-aluminum alloy powder on the corrosion behavior of 90/10 copper-nickel alloy. Design/methodology/approach Coatings of copper-aluminum alloy powder at different contents (Wt.% = 50%, 60%, 70% and 80%) were prepared by the high-temperature heat treatment process. The microstructure and component of the coatings were characterized by scanning electron microscope, X-ray diffraction, energy dispersive spectrometer and X-ray photoelectron spectroscopy. The electrochemical properties of the coating were explored by electrochemical impedance spectroscopy. Findings The results show that the aluminized layer was successfully constructed on the surface of 90/10 copper-nickel alloy, the composition of the coating was composed of copper-aluminum phase and aluminum-nickel phase, the existence of the aluminum-nickel phase was formed by the diffusion of Ni elements within the substrate and because of the diffusion, the Al-Ni phase was distributed in the middle and bottom of the coating more. The Al-Ni phase is considered to be the enhanced phase for corrosion resistance. When the copper-aluminum alloy powder content is 70 Wt.%, the corrosion resistance is the best. Originality/value The enhancement of corrosion resistance of 90/10 copper-nickel alloy by the copper-aluminum alloy powder was revealed, the composition of the aluminized layer and the mechanism of corrosion resistance were discussed.

Purpose This study aims to investigate the effect of changes in iron content in 70/30 copper–nickel alloy on the corrosion process. Design/methodology/approach 70Copper–30Nickel-xFe-1Mn (x = 0.4,0.6,0.8,1.0 Wt.%) alloy were prepared by the high frequency induction melting furnace. The scanning electron microscope, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy were used to analyze the morphology and component of the corrosion product film. Findings The results show that the corrosion resistance of 70/30 copper–nickel alloy added with 1.0%Fe is the best, and the film is divided into inner dense Cu2O composite film and outer hydration loose layer; XRD showed that after adding 1.0% Fe, the content of Cu2(OH)3Cl in the corrosion product film was significantly reduced, while the content of Cu2O remained unchanged; XPS showed that nickel accumulates in the inner layer of corrosion product film; the stage growth mode of the film, the role of nickel in it and the enrichment mechanism of iron in the inner film were summarized and discussed. Originality/value The changes in the composition and structure of the corrosion product film caused by the iron content are revealed, and the mechanism of the difference in corrosion resistance is discussed.

Marine Engineering

Copper–nickel alloy has the potential in sustaining the recent demands in advanced marine engineering applications. It has been found advantageous over other copper alloys due to the unique properties and corrosion resistance they possess. However, the structure of Cu–Ni alloy alone is not sufficient to withstand many applications, as the structure cannot perform efficiently in an aggressive environment. The performance of this alloy inherently depends on carefully select alloying compositions, as the alloying elements are associated with the precipitation of intermetallic particles that will enhance mechanical properties and corrosion resistance when designing the component of Cu–Ni alloys. A combination of alloying elements has been conceptualized in the designing of copper–nickel alloy. This review described the role of alloying elements in modifying the microstructural features through phase transformation and how it affects the improvement of the mechanical and physical properties of Cu–Ni based alloys. The effect of alloying elements on the structure and properties of Cu–Ni alloys have been critically summarized based on surveying the works done by authors on this category of structural modification binary Cu–Ni alloy.
