研究成果
The feasibility of Rapid Prototyping based on Laser Cladding to produce commercial pure Ti thin straight parts is demonstrated. The technique provides exclusive advantages for component manufacturing from precursor materials extremely difficult to work by conventional machining methods. The parts obtained were fully dense without cracks or pores, with a mean surface roughness of Ra=17.51 μm.
研究不足
The study focused on simple parts and did not explore complex geometries or the full range of potential applications. The process parameters were kept constant without monitoring-controlling systems producing changes on them.
1:Experimental Design and Method Selection:
Rapid Prototyping Based on Laser Cladding technique was selected to produce pure titanium parts. A fiber laser was used as a heat source to process cp-Ti powder.
2:Sample Selection and Data Sources:
Commercially pure titanium (cp-Ti) grade 4 particles with a size between 75 and 180 μm were used as precursor material.
3:List of Experimental Equipment and Materials:
Fiber laser delivering a maximum power of 200 W, Photron Fastcam 1024 high-speed video camera, SEM (Philips XL-30), EDS (EDAX PV9760), Optical Profilometry (Wyko-NT1100).
4:0).
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The precursor material was blown into a scanning laser beam in an inert atmosphere. The substrate was moved to create clads layer by layer.
5:Data Analysis Methods:
Generated parts were analyzed by OM, OP, SEM, and EDS to study morphology, microstructure, and composition.
