摘　　要：垃圾焚烧电站水冷壁高温腐蚀是影响垃圾焚烧炉稳定运行的重要因素,为了提高垃圾焚烧炉运行的安全性,研究者大多从基材的选择、施加表面防护涂层、温度控制等方面进行了研究。本文则主要针对施加表面涂层方面,研究了锅炉水冷壁镍基涂层高温氯腐蚀性能,利用SEM、EDS、XRD和光学显微镜等对合金涂层进行表面形貌和组织结构分析,并沿涂层深度方向进行维氏硬度测试和组织成分检测,探究其抗氯腐蚀机理。结果表明,镍基涂层在高温下耐腐蚀能力强,组织致密,没有孔隙、裂纹等较大缺陷,能够较好地耐氯盐腐蚀,保护垃圾焚烧炉水冷壁。The high temperature corrosion of water-cooled wall of the municipal solid waste incineration power plant is an important factor affecting the stable operation of the incinerator.In order to improve the safe operation of the waste incinerator,the existing improvement measures mostly involve the steel pipe selection,surface coating,temperature control and so on.In this paper,aiming at the application of surface coating,the high temperature chlorine corrosion performance of the nickel-based coating on boiler pipe was studied.The surface morphology,microstructure and composition of the alloy coating were characterized by means of optical microscope,vicker's hardness tester,SEM,EDS and XRD.The results show that the nickel-based coating has strong corrosion resistance at high temperature,there are no pores,cracks and other major defects in the coating.The coating can better resist the chloride corrosion and protect the pipeline steels of waste incinerator.
