| Abstract: |
| Remanufacturing engineering has become one of the key contents in the national developing strategic emerging industry. As a key technology for remanufacturing engineering, thermal spraying has the characteristics such as wide kinds of feed materials, little restriction on substrate geometry and dimensions, controllable coating thickness, simple processing management, low investment, high deposition efficiency and special surface properties. Thermal spraying can also be regarded as a key technology due to its capability of remanufacturing damaged parts and property upgrade. As a result, it performs a booming development applied in many equipment components remanufacturing in the industries such as national defence, printing, aerospace, petrochemical, mining machinery and electric power. In this study, the present status of research and typical applications of thermal spraying technologies used in remanufacturing field was reviewed, including supersonic atmospheric plasma spraying, high velocity flame spraying and high velocity arc spraying methods. The characteristics of the thermal spray techniques were analyzed, and some remarks on the future development of the technologies used in remanufacturing field were put forward, including enhancing the adaptability investigations of thermal spraying available for remanufacturing, the multitechnology researches and applications, the highefficiency and widescale industry study of thermal spraying and the related thermal spray remanufacturing standards or process criterions. |
