本文选用目前治理火电站受热面管道中常用的两种喷涂材料,结合高速电弧喷涂技术制备防腐涂层,利用扫描电镜、C-Ray衍射等试验手段对其腐蚀产物及腐蚀机理进行分析和探讨,为选材提供理论依据。研究结果表明,啧涂后形成的涂层具有典型的层状结构,较高的结合强度和硬度,涂层的耐高温冲蚀性能良好,同时常温和高温耐磨损性能也较高;适用于电站锅炉“四管”的防护。
In this paper, two kinds of spraying materials commonly used in the heating pipelines of thermal power plant are selected. Combined with high-speed arc spraying technology, anticorrosive coatings are prepared. The corrosion products and corrosion mechanism are analyzed and discussed by means of scanning electron microscopy and C-Ray diffraction. Provide a theoretical basis for material selection. The results show that the coating formed after the Tut coating has a typical layered structure, high bonding strength and hardness, good corrosion resistance of the coating at high temperature, high wear resistance at room temperature and high temperature; for Power station boiler “four tubes ” protection.
