Advances in the Metal-Based Hybrid Process of Additive Manufacturing

Topic Information

Dear Colleagues,

Due to its design freedom, additive manufacturing (AM) is widely adopted for manufacturing components for automotive to aerospace applications, food 3D printing, and healthcare applications. Compared to the conventional subtractive manufacturing methods, AM is versatile and satisfies the criteria for sustainability through net-zero manufacturing methods. Nowadays, researchers and industrialists are focused on an advanced option of AM: hybrid additive manufacturing. Hybrid additive manufacturing (hybrid AM) refers to multimaterial, multistructural, and multifunctional printing, as well as hybrid techniques and equipment. The hybrid capabilities of AM are rewriting material design norms and bringing a new dimension to designs for the additive manufacturing (AM) approach. Hybrid AM processes combine AM with one or more secondary techniques or energy sources that are completely linked and influence component quality, functionality, and process performance synergistically. Subtractive and transformational manufacturing methods such as machining, remelting, peening, rolling, and friction stir processing (FSP) are examples of secondary processes and energy sources. New economic and environmental tools, as well as sensor technologies that better support hybrid processing, are needed as interest in hybrid AM rises. Hybrid AM has entered the next evolutionary stage in additive manufacturing, with the potential to alter the way that items are manufactured. This Topic primarily focuses on the following areas of hybrid AM, but is not limited to:

• Hybrid additive manufacturing process 
• Hybrid additive manufacturing machines
• Friction stir additive manufacturing
• Ultrasonic vibration-assisted additive manufacturing
• Multi-material 3D printing 
• Multi-structural 3D printing 
• Hybrid post-processing, preprocessing, and in situ processing for additive manufacturing 
• Hybrid 3D-printed materials structure
• Nontraditional additive manufacturing process

A solid-state cold-spray technique was employed for depositing the copper-coated graphite reinforced copper-based composite coatings on aluminum alloy 6061 T6 substrate under different process parameters. The optimum process parameters of the cold-sprayed coatings were predicted in terms of surface roughness, thickness and adhesion. The surface roughness was measured using a 3D profilometer, the thickness and element constitution were detected by an optical microscope and scanning electron microscope furnished with an energy-dispersive spectral analyzer and the adhesion was detected by the scratch test method. The microstructures of the deposited coatings were also observed by a scanning electron microscope. The results show that when the coating is not oxidized and dense, the copper-coated graphite reinforced copper-based composite coating at 800 °C, 5.5 MPa, possesses the lowest surface roughness, the maximum thickness and the highest adhesion among the cold-sprayed coatings. In addition, the surface roughness, thickness and adhesion of the deposited coatings are all linear with particle velocity. Full article
