| 摘 要： | 以TiAl金属间化合物为烧结助剂对B4c陶瓷进行活化强化烧结，制备出B。c陶瓷基复合材料，通过电化学阻抗、扫描电镜等手段对其耐海水腐蚀性能进行了研究，并由此对其腐蚀机理进行了探索。在60d的浸泡过程中，海水对B4c复合材料的腐蚀主要表现为对材料中TiB2相的腐蚀，腐蚀过程可分为海水中有害粒子对材料表面氧化膜的穿透、海水对TiB2相腐蚀及TiB2相表面氧化膜重新生成3个阶段，材料的耐海水腐蚀能力呈先下降后上升的趋势。

| Abstract: | B4C matrix composite material was prepared through sintering using TiAl intermetallic compound as sintering additive.The marine corrosion behavior of the material was studied with electrochemical impedance spectroscopy,SEM,and sea water immersion methods.The results indicated that the corrosion process of the material can be mainly attributed to the corrosion process of TiB2 phase.The corrosion process included three stages:the harmful particles in seawater penetrate the oxide film on material surface;seawa... |
