Abstract

In this study, gas-atomized CuSn10 powders were used as raw materials to manufacture 3D-printing CuSn10 samples via powder extrusion printing (PEP) technology. A laser powder bed fusion (LPBF) CuSn10 sample was prepared for comparison. The friction and wear behaviour and corrosion resistance of CuSn10 alloy were investigated. The results showed that the PEP samples prepared from unscreened CuSn10 powders had high porosity, wear rate, friction coefficient and corrosion rate. However, the properties could be improved by adjusting the powder particle sizes, including friction and wear behaviour, wear surface roughness, corrosion resistance and so on. In particular, the PEP CuSn10 samples prepared from less than 1000 mesh powders exhibited the lowest wear rate, friction coefficient and corrosion rate, which were 3.06 × 10⁻⁶ mm³ N⁻¹ m⁻¹, 0.565 and 0.0411 mm per year. In addition, the PEP samples prepared by the combination of coarse and fine powders exhibited a relatively smooth wear surface. On the contrary, the wear surface of the LPBF sample had some large furrows and high surface roughness after performing the friction and wear test.

粉末挤压印刷CuSn10合金摩擦磨损性能及耐腐蚀性能的研究

本研究以气雾化CuSn10粉末为原料，采用粉末挤压打印（PEP）技术制备3d打印CuSn10样品。制备了激光粉末床熔合CuSn10样品进行比较。研究了CuSn10合金的摩擦磨损性能和耐蚀性。结果表明，未经筛选的CuSn10粉末制备的PEP样品具有较高的孔隙率、磨损率、摩擦系数和腐蚀速率。然而，可以通过调整粉末粒度来改善其性能，包括摩擦磨损性能、磨损表面粗糙度、耐腐蚀性等。其中，小于1000孔的PEP CuSn10样品的磨损率、摩擦系数和腐蚀率最低，分别为3.06 × 10−6 mm3 N−1 m−1、0.565和0.0411 mm /年。此外，粗粉和细粉组合制备的PEP样品具有相对光滑的磨损表面。与此相反，经过摩擦磨损试验后，LPBF试样的磨损表面出现了较大的沟槽，表面粗糙度较高。
