C+Ti注入样品经过腐蚀和点蚀后用透射电子显微镜发现了抗腐蚀的丝状纳米相.多重电位扫描法研究表明这种相具有抗腐蚀和抗点蚀特性,其腐蚀电流密度下降10～26倍.X射线分析表明这种相为直径10～30nm的FeTi和FeTi2相,这种相密集的镶嵌在注入层中,其长度大约为150～320nm.腐蚀后用扫描电子显微镜观察到密集的丝状的抗腐蚀和抗点蚀的纳米结构.这种丝状纳米相是金属碳化物,这些相构成了具有优异抗腐蚀特性的钝化层.
Corrosion-resistant filamentous nanophases were observed by transmission electron microscopy after corroded and pitted samples were implanted with C + Ti.Multiple potential scanning studies show that this phase has anti-corrosion and anti-pitting properties and its corrosion current density is reduced by 10 ~ 26 times.X-ray analysis showed that this phase is 10 ~ 30nm in diameter FeTi and FeTi2 phase, this phase inlaid inlaid in the injection layer, the length of about 150 ~ 320nm.Ecrossed with a scanning electron microscope to observe the dense Filament-like corrosion and pitting resistant nanostructures. This filamentous nanophase is a metal carbide that forms the passivation layer with excellent corrosion resistance.
