摘　　要：连续热镀锌生产线锌锅部件受到锌液腐蚀、磨蚀、锌渣粘附等影响,提高锌锅部件的使用寿命既能提高镀锌板产品质量,又能降低成本,提高效率。本文介绍了热喷涂技术在制备锌锅辊涂层、轴承/轴瓦涂层中的研究和发展状况,分析了各种热喷涂方法的技术和工艺要点,综述了锌锅部件涂层材料的发展过程,展望了热喷涂技术制备锌锅部件涂层的应用和发展趋势。The failure forms of zinc pot hardware in continuous hot-dip galvanizing lines （CGLs） are Zn corrosion, abrasion and doss build-up. Enhancing the life of the pot hardware will not only upgrade the quality of sheet plate product but also increase the efficiency of CGLs with cost decreasing and energy saving. The paper introduces the current research and development of thermal spray coating in pot rolls, sleeves ＆ bushings, and analyses the characteristics of various thermal spraying technologies, and overviews the developing process of coating materials. At last, it gives the prospect of application and developing trend of thermal spray coating technology in pot hardware.
