| 摘要: |
| 利用表面工程技术对失效零部件进行恢复性维修是对机械产品进行维修和再制造的重要手段。通常，恢复性维修在零件表面增加了一个表面涂（覆）层，因此，检测零件维修与再制造过程中增加的表面涂（覆）层质量，评价零件表面性能是否达到使用需求，对确保机械零部件维修与再制造的质量具有重要的意义。文中从表面成分与结构分析、表面形貌与组织分析、表面残余应力检测、表面力学性能检测和表面耐腐蚀性能检测等五个方面阐述了机械零件维修与再制造表面质量分析与检测的内容，介绍了常用的测试方法、设备及其特点，重点介绍了表面质量分析和检测技术在利用真空镀膜、电刷镀、激光熔覆以及超音速等离子喷涂等先进表面工程技术制备涂层质量检测中的应用，并给出了具体的应用实例。 |

| Abstract: |
| The restorative maintenance of failure parts by surface engineering technologies is an important means of repair and remanufacturing of mechanical products. Usually, a new surface coating is obtained on the surface of repaired parts, so it is of great significance to ensure the quality of repaired and remanufactured parts by identifying the surface quality of the coating and assessing the surface properties of the parts. In this paper, surface quality analysis and measurement of the repaired and remanufactured parts were presented from different aspects of the surface composition and structure analysis, surface morphology and structure analysis, surface residual stress testing, surface mechanical properties testing and surface corrosion resistance testing. The test methods and equipment commonly used and their characteristics were introduced. It is focused that the surface quality analysis and measurement of coatings prepared by vacuum coating, brush plating, laser cladding and the supersonic plasma spraying and other advanced surface engineering technology. And several application examples were given. |
