Item Lead-free solders for high-temperature applications(Association of American Publishers, 2025) Satyanarayan, S.; Narayan Prabhu, K.Due to the toxicity of Pb, efforts to develop alternatives to Pb-based solders have been increased significantly. However, only a limited number of lead (Pb)-free solder systems exist for high-temperature applications. In the present paper, a review of the selection of Pb-free solder alloys for high-temperature (300°C–400°C) applications to replace traditional Pb-based alloys is carried out. A discussion on the research and development of high-temperature solder alloys is highlighted in the current review. The solder systems with alloying additions like Au, Sb, Ni and Zn must be investigated to be used as potential candidate materials for high-temperature applications © 2025 by authors.Item Thermal spray coatings in industrial boiler environments: A review.(Association of American Publishers, 2025) Anil Pinto, J.; Narayan Prabhu, K.Fired Boilers are integral parts of modern Petroleum Refineries and Thermal Power Plants where their reliability directly impacts both the productivity and financial performance. The pressurized components of these boilers are susceptible to various corrosion mechanisms, which can affect the reliability of the boilers. Over the years, a range of corrosion mitigation strategies have been explored and implemented across the industry, yielding varying levels of success. Based on extensive research and field trials, thermal spray coatings have emerged as a promising solution, offering cost-effective corrosion protection. This paper offers a comprehensive overview of thermal spray coatings as an effective strategy for corrosion prevention in industrial boiler environments. Thermal conductivity considerations in the selection of coating materials is highlighted. © 2025 by authors.
