Mechanical, thermal, and corrosion properties of Cu-10Sn alloy prepared by laser-powder-bed-fusion additive manufacturing

In this study, the production of full-density Cu-10Sn bronze parts by selective laser melting (SLM) technique and the examination of microstructural, mechanical and corrosion properties were carried out. Cu-10Sn pre-alloyed powders produced by gas atomization technique were shaped using SLM technique within selected parameters and then microstructural properties were determined. Depending on the microstructural properties, the mechanical and corrosion behaviors were determined. The obtained results were compared with similar bronze materials produced by conventional methods. Different characterization techniques were used for microstructural characterization. The microstructure of the Cu-10Sn alloy was observed to consist of dendritic primary α and δ-Cu41Sn11 phases. According to the mechanical test results of the samples produced at densities of 8.75 g cm-3 at room temperature, the yield strength was measured as 420 MPa, the tensile strength was 578 MPa, the elongation was 32 % and the hardness value was 160.3 HV0.2. For the electrochemical experiments, the corrosion rate of the samples was found to be 4.38 mpy. As a result of the productions and experiments, it was determined that the samples produced by the SLM method provide very good mechanical and corrosion properties compared to the literature.

“…Mechanical fatigue is the most damaging type of material degradation. It is responsible for 80-90% of the related failures [1], making the study of the fatigue performance and the design of fatigue-resistant metals crucially important [2][3][4][5][6]. Rich volumes of literature offer different theoretical [7][8][9] and experimental [6,10] approaches to predict fatigue life, among which microstructure-sensitive and thermodynamically-based models are becoming widespread [11][12][13].…”

“…In both studies, the temperatures during stress relief annealing were considered too low to significantly reduce the corrosion behaviour. Zeng et al [ 20 ] have reported that annealing at 600 °C for CuSn leads to improved corrosion resistance and larger grains. Furthermore, an XR measurement shows that after annealing, only al-pha-Cu(Sn) is present, while alpha and delta (Cu41Sn10) are found before annealing.…”

Corrosion Resistance of 316L/CuSn10 Multi-Material Manufactured by Powder Bed Fusion

Research and industry are calling for additively manufactured multi-materials, as these are expected to create more efficient components, but there is a lack of information on corrosion resistance, especially since there is a risk of bimetallic corrosion with two metallic components. In this study, the corrosion behaviour of a multi-material made of 316L and CuSn10 is investigated before and after a stress relief annealing using linear sweep voltammetry. For this purpose, a compromise had to be found in the heat treatment parameters in order to be able to treat both materials together. In addition, additively manufactured and rolled samples were investigated and used as a reference. Interaction of the two materials in the multi-material could be demonstrated, but further investigations are necessary to clearly assess the behaviour. In particular, the transition region of the two materials should be investigated. In this study, a stress relief heat treatment at 400 °C caused a slight improvement in the corrosion resistance and reduced the scatter of the measurements significantly. No significant difference was measured between the additively produced and rolled samples.
