| 中文摘要: |
| 冲刷腐蚀广泛发生在石油、化工等领域，并致使设备材料发生损伤或失效。材料经激光熔覆后得到具有特殊化学、力学性能，并能与基体材料形成冶金结合的涂层。从激光熔覆层冲刷腐蚀行为研究方法出发，简要概括了现场测试法、数值模拟法以及通过模拟真实工况进行实验室研究的三大类实验装置的优缺点，并对目前用于激光熔覆层冲刷腐蚀行为的表征方法进行了总结。然后介绍了激光熔覆层冲刷腐蚀机理的研究现状：冲刷腐蚀机制由电化学腐蚀、机械力磨损及二者交互作用构成，其中冲刷主要通过正应力和切应力两种侵蚀机制对腐蚀产生促进作用，而腐蚀则通过弱化涂层表面促进冲刷。随后，总结了激光熔覆层冲刷腐蚀行为的影响因素，并对熔覆材料自身因素、流体因素（流速、冲蚀角、固体颗粒及pH值、温度等）对激光熔覆层冲刷腐蚀行为的影响规律进行了分析和归纳。最后，基于冲刷腐蚀机理研究现状，从研究方法及影响因素等方面总结了目前激光熔覆层冲刷腐蚀研究中存在的问题，同时对未来的研究趋势进行了展望。 |
| 英文摘要: |
| Erosion-corrosion occurs in petroleum, chemical engineering and other fields, and causes damage or failure of equipment materials. After laser cladding, the material has special chemical and mechanical properties and can form a metallurgical bond with the matrix material. Based on the research method of erosion-corrosion behavior of laser cladding layer, the advantages and disadvantages of field test method, numerical simulation method and three kinds of experimental devices by simulating real working conditions were briefly summarized, and the current characterization methods used for evaluating erosion-corrosion behavior were also concluded. Then, the research status of the erosion-corrosion mechanism of laser cladding layer was introduced. The erosion-corrosion mechanism was composed of electrochemical corrosion, mechanical force wear and the interaction of the two. The erosion mainly promoted corrosion through two erosion mechanisms of normal stress and shear stress, while corrosion promoted erosion by weakening the surface of the coating. Subsequently, the influencing factors of the erosion behavior of laser cladding layer were concluded and the effects of fluid factors such as flow rate, erosion angle, solid particles and pH value, temperature and other liquid phase factors on the erosion-corrosion behavior of laser cladding layer were analyzed and summarized. Finally, based on the research status of erosion-corrosion mechanism, the problems in the research of erosion-erosion of laser cladding layer are summarized from the research methods and influencing factors. At the same time, the future research trends are prospected. |
