| Abstract Scope |
The Directed Energy Deposition (DED) process is a 3D printing additive manufacturing technology that simultaneously deposits laser energy and metal powder to create a molten pool, and then solidifies it through layering. The DED process offers the advantages such as few geometric constraints, ease of repair, and rapid manufacturing capabilities. Titanium powder coatings generally exhibit excellent corrosion resistance, hardness, and wear resistance, making them widely applicable in industries such as aviation, automotive, and medical fields. Numerous studies have investigated the influence of machining parameters on the microstructure of titanium parts produced using DED. However, the effect of powder recycling on the microstructure and mechanical properties of titanium has not been systematically studied. In this study, various powder property evaluations, including particle size, flow rate, flowability, and ONH analysis, were conducted to evaluate whether titanium powder could be recycled. Subsequently, the distribution and formation mechanisms of the available powders were considered. |
