Abstract High-temperature corrosion of critical components such as water walls and superheater tubes in biomass/waste-fired boilers is a major challenge. A dense defect-free thermal spray coating has been shown to be promising achieve high electrical/thermal efficiency power plants. The field spraying quality coatings have progressively evolving; therefore, assessment our understanding the efficacy increasingly aggressive operating environments plants can highly educative. effects composition microstructure on high-temperature behavior were discussed first part review. present paper that second review covers emerging research performance harsh corrosion-prone provides comprehensive overview underlying mechanisms lead damage exposed coatings. application contemporary analytical methods for better corrosion-resistant also discussed. discussion based an exhaustive literature unbiased commentary advanced accomplishments some outstanding issues warrant further research. An current status field, gaps scientific understanding, needs expansion applications provided.
