【摘要】 针对电站锅炉受热面管的防护,应用超音速活性喷涂系统研制镍基复合活性功能涂层。通过金相组织分析、扫描电镜检测以及X射线衍射分析,证明该涂层具有良好的组织形貌。高温腐蚀试验也说明了涂层能够耐受高温腐蚀。更多还原

【Abstract】 Aiming at the protection of heating surface tubes of utility boilers,Ni-based alloy coating has been developed by means of the technique of high velocity activated arc(HVAA) spraying.In order to test its technical quality,metallographic structure analysis,scanning electron microscopy (SEM) test,X-ray diffraction analysis as well as high-temperature erosion test were made.The results certify that the coat can be applied to the protection of heating surface tubes.更多还原
