摘要
利用光内送粉技术对小间隙双层斜套的成形工艺进行了研究,采用依次独立堆积路径、法向分层、无错位堆积工艺方法成形了双层斜套。实验结果表明,该工艺可以提升激光成形双层斜套的效率,节约金属粉末,有效保证薄壁件的厚度均匀性和双层斜壁之间的间距稳定性。成形件表面形貌平整,显微组织致密均匀,无裂纹、气孔等缺陷,显微硬度分布均匀。
Abstract
By means of the technology of inside-beam powder feeding, the formation technology of double-inclined-walled parts (DIWPs) with small gapsis is investigated. By using the methods of sequentially independent accumulation path, normal layering, and non-dislocation accumulation, the DIWPs are formed. The experimental results indicate that the technology proposed can increase the forming efficiency of DIWP, save metal powder, and ensure the thickness uniformity of thin-walled parts and the gap stability of the double inclined walls. The formed parts have smooth surfaces, uniform morphology, no cracks, no holes and no other defects, and uniform microhardness distributions.
