| Abstract Scope |
Additive repair by the process of directly printing metals onto damaged parts has significant potential to reduce costs of maintenance and repair operations, especially in the marine and shipbuilding industry. In this study, additive repair of Duramold-2™ (Al-Cu-Ni-Fe-Mg) cast alloy was conducted by deposition of AlSi10Mg through selective laser melting (SLM). The microstructure of the additively repaired aluminum, including the interface, was investigated using advanced electron microscopy techniques. Excellent bonding between the AlSi10Mg and Duramold-2™ substrate was observed. Mechanical assessment of repaired samples, including micro-hardness measurements and uniaxial tensile testing, supported the microscopy observations. The fracture surface of tensile specimens was also investigated, where failure was consistently observed in the substrate. The SLM-AlSi10Mg repair material reliably possessed better performance than the substrate, mainly due to its refined microstructure. |
