摘要： Heterogeneous manufacturing is a topic that continues to receive attention. As an emerging manufacturing technology, additive manufacturing can provide strong technical support for heterogeneous manufacturing. In this study, both homogeneous and heterogeneous composite tubular bionic components were fabricated based on the cold metal transition technology, and the influence of deposition current on the microstructure and mechanical properties of the components was studied. The results show that the interface of the as-deposited heterogeneous composite component is well bonded, and there is an obvious mechanical interlocking structure. The compressive yield strength and elongation of the heterogeneous composite components are higher than those of the homogeneous components, and are positively correlated with the deposition current. Due to the fluctuation of element content, there are a large number of fine grain structures at the interface of the heterogeneous composite components, which increases the mechanical properties.
