| 中文摘要 | HAYNES® 282®是一種透過形成𝛾/ 𝛾'超晶格強化之鎳基超合金,高溫下擁有卓越的機械性能與抗腐蝕性,使其成為先進超超臨界(A-USC)燃煤發電系統中的候選結構材料。相較傳統熱處理法,毫秒級脈衝雷射可在極短時間內產生高能量光子束對材料進行高效且精確的加工。本研究利用熱重分析儀(TGA)對不同功率脈衝雷射加工後之HAYNES® 282®進行750 ℃下48小時的質量變化行為分析,其質量變化結果符合拋物線曲線。此外,使用X光繞射儀(XRD)、帶有能量色散X射線分析儀(EDS)的高解析度場發射式電子顯微鏡(HRFEG-SEM)探討HAYNES® 282®氧化層結晶結構、成分分析與表面、橫截面形貌以了解其潛在機制。本研究結果有助於了解HAYNES® 282®在不同雷射功率加工下的氧化性能和動力學,為先進發電技術高溫材料的設計和開發提供突破的線索。 |
| 英文摘要 | HAYNES® 282® is a nickel-based superalloy that is strengthened by forming a γ/γ' superlattice, providing excellent mechanical properties and corrosion resistance in high-temperature environments, thereby serving as a candidate structural material for advanced ultra-supercritical (A-USC) coal-fired power generation systems. Compared with traditional heat treatment methods, millisecond pulsed laser can generate high-energy photon beams in brief duration for efficient and precise material processing. This work employed a thermogravimetric analyzer (TGA) to examine the mass gain characteristics of HAYNES® 282® subjected to various pulsed laser powers at 750 ℃ for 48 hours, with the mass gain results fitting to a parabolic curve. Moreover, X-ray diffraction (XRD), high-resolution field emission electron microscopy (HRFEG-SEM), and energy-dispersive X-ray spectroscopy (EDS) were employed to analyze the crystal structure, composition, and morphology of the surface and cross-section of the oxide layer of HAYNES® 282®to clarify the potential mechanisms. The results of this study help to understand the oxidation performance and kinetics of HAYNES® 282®under different laser power processing, providing clues for breakthroughs in the design and development of high-temperature materials for advanced power generation technology. |
