一种焚烧炉水冷壁防护兼抗结垢功能梯度涂层及制备方法
By employing a dual-layer gradient coating design on the water-cooled wall of the incinerator—combining supersonic arc spraying of metal ceramics and cold spraying of fluorine-modified organic composite materials—the high-temperature corrosion and scaling problems of the water-cooled wall were solved, resulting in improved corrosion resistance, anti-scaling properties, and heat transfer performance, while reducing construction and maintenance costs.
