| 摘要: |
| 为了科学评价再制造技术发展现状和竞争力，对再制造关键技术进行了分类、梳理和分析。采用文献计量学方法，重点分析了与废旧机电产品再制造相关的11项技术的国内外科技文献（SCI、CNKI）发文及专利申请情况，评价了再制造技术研究热点与趋势、研究水平和领先国家的技术发展态势。结果表明，再制造技术研究论文年均增长率达14.0%，专利年均增长率达27.8%。国外再制造技术热点主要集中在绿色清洗、无损检测与寿命评估、激光熔覆修复成形等，我国多集中在无损检测与寿命评估和修复成形两方面。我国再制造技术研究论文总体水平与发达国家还有较大差距，但部分再制造关键技术取得突破，已形成我国“尺寸修复、性能提升”的技术特色。我国在未来再制造技术体系构建中，应加强3类技术的协调发展，重点研发增材再制造技术、高效表面修复技术、智能先进涂层修复技术、绿色清洗技术以及无损检测与评估技术。 |

| Abstract: |
| To evaluate the state of the art and competitiveness of the remanufacturing technologies, the key technologies of the remanufacturing technologies were carefully analyzed in this paper. Domestic and foreign literatures and patents of eleven remanufacturing technologies about waste mechanical and electrical products from SCI and CNKI were analyzed. The research hot areas, development trends, research level of the remanufacturing technologies, and the development trends in leading countries were evaluated. Results show that the annual growth rate of published research papers about remanufacturing technologies is about 14% and that of patents is about 27.8%. The research hot areas of remanufacturing technologies in the foreign countries focus on green cleaning, nondestructive testing and life evaluation and laser cladding maintaining. Meanwhile, the hot research areas in China focus on nondestructive testing and life evaluation and maintaining technologies. Although the total quantities of published research papers of the developed countries are far more than that of China, major breakthroughs in some of remanufacturing technologies are made and special features like "dimension repairing and performance promoting" are formed in China. The direction of the system of remanufacturing technologies is pointed out. Three categories of remanufacturing technologies need to be developed coordinately and the priority research areas should focus on material increase remanufacturing technologies, high efficiency surface maintaining technologies, advanced intelligence coating systems, green cleaning technologies and nondestructive testing and evaluation technologies. |
