摘要：

With the National Double Carbon Strategic Goal,waste-to-energy has become a mainstream technology for municipal waste treatment‧ However,a safety problem is the high corrosion thinning in the boiler pipes of waste powerplants,which can result in leakage and bursting‧ In this paper,the characteristics of the base material and mainstream coating-protection technologies for pipes under high parameter conditions were reviewed based on the boiler corrosion law‧ In particular,this work focused on inconel overlay welding,induction fusion welding,high-velocity oxygen fuel,and other technologies and their performance‧ The existing design systems for coating systems match the pipe substrate,coating material,and coating process with the matching parameters as the main evaluation indices‧ Thus,different parameters,such as the thermal expansion coefficient,thermal conductivity,bond strength,porosity,service life,and economical feasibility,were systematically evaluated‧ Moreover, their role on the design of anticorrosion coatings,including the thickness,structure,and components,was elucidated‧ Considering the current problems in coating-protection technologies,an integrated research for powder synthesis and coating structure design,and service performance evaluation was proposed‧ Based on current system designs focused on FeCr and NiCr alloys with high Cr contents,the addition of W,Mo,and other elements as supplements to NiCr-based coating materials improved the corrosion and wear resistance‧ Finally,the future prospects for the development of coating-protection technologies are presented‧ © 2024 Cailiao Daobaoshe/ Materials Review.
