摘　　要：金属零件直接制造技术目前已成为快速成形技术的研究热点和重要发展方向。提出一种基于微束等离子熔覆工艺的直接金属成形方法,介绍该方法的工作原理和系统构成,设计并开发基于等离子熔覆的金属零件直接制造软、硬件系统,并采用该系统进行中空零件成形实验。实验结果表明,并采用微束等离子熔覆直接制造系统可以得到成形良好、组织细密的金属零件。Direct fabrication of metal components becomes one of the most interesting fields in the research and development of rapid prototyping technology at present. A directly metal forming technique was presented based on micro plasma arc cladding. The principle of process and structure of forming system were introduced, and the hardware and software of directly metal forming system were implemented. A hollow cylindrical part experiment was carried out. The experimental result shows that full-density metal components with compact texture can be obtained by the developed forming system.
