Fe對金剛石刻蝕反應的相分析

Identification of Phases for Etching Interaction of Fe with Diamond

摘要: 研究了950 ℃保溫6 min時Fe對金剛石的刻蝕反應.用AES微區成分分析給出了金剛石晶格中的C原子，自金剛石與Fe的相界面溶入Fe中的分布，并通過AESCKLL譜確認了溶入Fe中C的存在狀態是石墨，而無碳化物相形成.

Abstract: The etching interaction of Fe with diamond was studied after sintering at 950 ℃ for 6 min. According to the result of AES C KLL line, the state of carbon near the diamond-iron interface was determined to be considered as graphite but not Fe₃C. Carbon atom is dissolved from diamond crystal lattice into iron.
