Al bronze are the choice of material for relatively high wear applications besides appreciable mechanical and corrosion properties. In present work, the effect of different heat treatment processes on tribological characteristics of Ni-Al bronze (CuAl10Ni5Fe4, UNS C63000) has been studied. The hot rolled bar of 30 mm diameter was subjected to annealing, quenching and aging processes separately, consequently their effect on microstructure was studied and co-related with tribological characteristics. The formation and nucleation of various phases due to the thermal treatments were observed using optical microscopy. The wear behavior was studied using ball on disk arrangement with 100Cr6 ball and Ni-Al Bronze samples as disk. The characteristics and mechanism of wear track was studied using scanning electron microscope. It was observed that the water quenched sample followed by aging at 300°C exhibited best tribological characteristics.

AbstractHere, the corrosion properties of chromium (Cr) added to a copper-aluminum-nickel (Cu-Al-Ni) alloy were studied. Primarily, the alloy samples were prepared by increasing the percentages of Cr composition in the following series of 4%, 8% and 12% by keeping other alloying elements as constants. The alloy was made using the powder metallurgical technique. Consequently, hot forging was done on the sintered specimen. Both hypothetical and authentic densities were found for the hot forged samples which showed that the densities kept on increasing with the addition of Cr. The Cr embellishments were exposed using optical microscopy of varying magnifications. The corrosion properties achieved from the potentiostat showed that the corrosion resistance upsurges more than the other commercially available nickel-aluminum-bronze (NAB) alloys due to the Cr embellishments. The corroded surface was then investigated using scanning electron microscopy (SEM) which disclosed the formation of different κ phases along with an α matrix and other intermetallic phases in the present alloy. Furthermore, hardness tests were taken and these established that the hardness increases with Cr accompaniments. Thus, the present alloy can be endorsed as a novel material (Cu-Al-Ni-Cr) in the propellers of ships in which both hardness and corrosion resistant are obligatory.

The Impact

The effect of dopant and heat treatment on the microstructure and mechanical properties of Nickel-aluminum bronze (Cu-10%Al-5%Ni-5%Fe-x%Mo) were extensively investigated. The cast samples were heat treated through different processes, including solutionizing, quenching, and aging; their microstructures were examined using an optical microscope, scanning electron microscopy and energy dispersive spectroscopy analysis and their mechanical properties determined. The microstructure of the as-cast samples consisted of Cu-rich ‘α-phase, ‘κ-phases and small volume fraction of β'-phase while solutionizing transformed the β'-phase to a homogenous β-phase, α, and κ phases. Quenching transformed all β phase to β'-phase, however, aging the alloy precipitated fine dispersive strengthening κ-phases from the quenched microstructure. The results of the mechanical tests showed that the aged samples had improved excellent mechanical properties compared to the as-cast samples. Compared to the base alloy, the tensile strength and hardness of the aged 2% Mo sample increased by 58% and 55%, respectively while the impact strength and elongation decreased by 27% and 22%, respectively. Similarly, the tensile strength and hardness of the aged 3% Mo sample increased by 44% and 49%, respectively, while the impact strength and % elongation decreased by 23.9% and 24.9%, respectively.
