Application of Arc-Sprayed Nickel-Chromium-Molybdenum Alloy Coatings for Corrosion Protection in Flue Gas Desulfurization Systems of Thermal Power Plants

Flue gas desulfurization (FGD) is the process of removing sulfur oxides from the gaseous byproducts generated during the combustion of fossil fuels. Traditional combustion technologies cause most of the sulfur contained in fuels to be oxidized and released into flue gases, contributing to the formation of "acid rain." Acid rain refers generally to the deposition of various acids in the atmosphere, which can harm both the environment and human health. Acid rain has become a major concern for governments worldwide. While energy conservation and the substitution of low-sulfur fuels for high-sulfur fuels have played a role in reducing overall pollution, it remains necessary to adopt technologies for removing sulfur oxides. Currently, the wet-process method, which uses alkaline slurries such as lime/limestone slurry, is the primary approach employed.

Application scope of supersonic cold spraying

Used for coating amorphous materials and multilayer coatings, particularly on surfaces of materials that are either non-heat-resistant or have limited heat resistance—for example, in preparing insulating coatings for plastic materials or ultrafine metal powder coatings.
