“…manufacturing techniques: Properties of nickel aluminium bronze conventionally manufactured using techniques such as traditional (gravity) and centrifugal casting [14,15], hot forging [16], friction stir processes [17] for further improvement of materials properties, hot forging, cold working (used especially for high ductility materials to improve materials performance, on the other hand, high strength materials are hard to cold work due to their brittleness aspect) are highlighted in Table 2. Comparing with these manufacturing techniques and others [18][19][20], we can see that L-PBF has proved its efficiency in providing good combination of properties.…”

To cope with the increasing demands of high-performance materials, efforts were made using Laser Powder Bed Fusion technique (L-PBF), taking advantage of its extremely short solidification time to fabricate copper alloy with highly refined microstructure. Copper and Copper alloys are reputed for their high reflectivity resulting in low laser absorption, which makes their 3D fabrication process very challenging. This study aims to provide high density samples in order to obtain high mechanical and tribological properties. This objective is realized through the optimum energy density value which is obtained by monitoring laser power P, scan speed v, hatch space h and layer thickness t. Upon mapping of optimum parameters, the best combination is adopted to manufacture the samples of this study. Mechanical and tribological characterization of nickel aluminium bronze alloy confirmed the efficiency of laser powder-bed fusion (L-PBF) in providing high performance materials, higher properties such as wear resistance, tensile strength and hardness were obtained compared to other manufacturing techniques.

“…In mold technology, Cu-Al bronzes compete with several alloys, therefore, it is necessary to investigate their tribological characteristics under both dry and wet conditions. Several reports on Cu-Al bronzes [12][13][14][15] indicated that both processing conditions and final microstructure determined their corrosion or wear performance however findings lacked selection of proper bronze for industrial applications, where wear and corrosion phenomena competed. In this study, it is aimed to investigate the tribological behaviour of Cu-Al-X alloys immersed into NaCl solution in order to understand the tribo-corrosion performance.…”

Among the copper based alloys, Cu-Al-X bronzes are commonly used as mold materials due to their superior physical and chemical properties. Mold materials suffer from both wear and corrosion, thus, it is necessary to know which one of the competitive phenomenon is dominant during the service conditions. In this study, tribo-corrosion behavior of CuAl10Ni5Fe4 and CuAl14Fe4Mn2Co alloys were studied and electrochemical measurements were carried out using three electrode system in 3.5 % NaCl solution in order to evaluate their corrosion resistance. In tribo-corrosion tests, alloys were tested against zirconia ball in 3.5 % NaCl solution, under 10N load with 0.04 m/s sliding speed during 300 and 600 m. The results indicate that (i) CuAl10Ni5Fe4 alloy is more resistant to NaCl solution compared to CuAl14Fe4Mn2Co alloy that has major galvanic cells within its matrix, (ii) although CuAl10Ni5Fe4 alloy has lower coefficient of friction value, it suffers from wear under dry sliding conditions, (iii) as the sliding distance increases, corrosion products on CuAl14Fe4Mn2Co surface increase at a higher rate compared to CuAl10Ni5Fe4 leading to a decrease in volume loss due to the lubricant effect of copper oxides.

“…However, these materials are considered to be attractive in their high rigidity, tensile strength, corrosion resistance and abrasion resistance (Alam et al, 1996;Yuanyuan et al, 2003). It is hard process to produce this alloy by conventional casting methods owing to low hardening spacing and a þ g 2 phases forming at 5658C.…”

AbstractPurpose -The paper's aim is to examine dry friction properties of the wear behaviors of the manufactured aluminum bronzes (C9500 and C95300) by using pin-on-disk type wear test device. Design/methodology/approach -In this study, alloys were produced by casting C95200 and C95300 aluminum bronzes norms. Produced aluminum bronzes ingot after homogeneous were formed for wearing specimen. These test were conducted on two different alloys, in the sliding velocities 1, 1.5 and 2 m/s, with four different load (25, 37.5, 50 and 62.5 N) and for four different space (500, 1,000, 2,000 and 4,000 m). Wearing specimens tested for hardness and investigated in order to spectral electron microscope photographs. Findings -After investigation, C95200 grain size was bigger than C95300. Furthermore, C95300 alloys were harder than C95200 because of more aluminum. Increasing load, sliding velocity and distance causes increasing wear. Coefficient of C95200 alloys was higher than C95300. Research limitations/implications -Aluminum bronzes show different properties according to the additional elements in them. Reliability of aluminum bronzes can be achieved by the control of chemical composition and the manufacturing method.Practical implications -Very useful information for industries using or planning to produce C95200 and C5300 alloys is provided. Originality/value -This paper identifies a resource need and offers practical help for a manufacturing operation.
