| 摘 要： | 基于等离子弧焊的直接金属成形方法是一种新型的快速成形工艺。对采用304L不锈钢作为单一熔覆材料的成形试验研究表明：电流、成形速度与成形轨迹宽度的关系可以采用平面几何关系表示。对成形件进行的密度、强度和硬度指标测试和金相组织观察表明：基于弧焊的直接金属成形件的组织结构和力学性能指标明显优于选择性激光烧结工艺成形件，达到或高于铸造零件。

| Abstract: | Direct metal forming based on plasma arc welding is a novel rapid prototyping process. Using 304L wire as the cladding material, the experimental results proved that the relationship among welding bead width, welding current and speed could be expressed with a plane in an X-Y-Z coordinate. Examination of the density, strength, hardness and microstructure showed that the mechanical properties and structure of the part made by direct metal forming process are better than that obtained from selective laser sintering Process,as good as or even better than castings. |
