摘要：

Thermal energy storage (TES) using metal alloys as phase change material (PCM) is a promising technology for generating cost-effective dispatchable power from concentrated solar power (CSP). However, the containment of a metal alloy PCM is challenging due to the corrosivity of molten metals to metallic containers at the high operating temperatures targeted in next-generation CSP plants. Ceramic based protective coatings could be used to extend the lifetime of metallic containment materials, such as stainless steels, in direct contact with molten metal alloy based PCM. This work investigates the corrosion prevention performance of a boron nitride-based coating on stainless steel exposed to molten Al-Si alloy. The coating was effective for corrosion prevention and stable after 720 successive melting and solidification cycles.
