摘　　要：由于受到液态锌的腐蚀、磨蚀、锌块冲击以及锌渣附着等因素的影响,热镀锌技术设备的使用寿命十分短暂。热喷涂技术能改善镀锌设备的抗熔融液锌腐蚀并能降低成本,还能提高能源利用效率和生产效率。热喷涂技术包括超声速火焰喷涂、爆炸喷涂、等离子喷涂、激光熔覆和等离子喷涂-激光熔覆等技术,这些技术制备的覆盖层普遍存在气孔、微裂纹、与基体结合不牢固等缺陷,使用寿命大大减少。开发一种与基体结合强度高、致密性好和缺陷少的热喷涂技术,满足实际生产需要是今后技术发展的重点。The service life of zinc plating equipment is very short owing to the influence of liquid zinc corrosion,abrasion,block impact and slag adhesion.Thermal spraying can improve molten zinc corrosion resistance of galvanizing equipment,reduce cost,enhance energy and production efficiency.However,related technologies have many disadvantages,which will considerably shorten the operation life of composite material.The development of thermal spraying that can meet actual production requirements will become a definite research trend in future.
