Abstract

The corrosion is one of the prime factors responsible for losses/degradations occurring in the materials. The zirconium-based amorphous alloys were investigated for assessing their robustness against corrosion. Corrosion behavior under pristine and oxygen-implanted conditions was compared in three acidic media. To study the effect of fluence on corrosion resistance, implantation was performed at three fluence rates, with the highest fluence (3 × 10¹⁷ ions/cm²) showing the best corrosion resistance. The appearance of crystalline phases subjected to the oxygen ion implantation was identified and verified using grazing incidence X-ray diffraction (GIXRD), field-emission scanning electron microscopy (FESEM) micrographs, and X-ray photoelectron spectroscopy (XPS). Quantitative EDS analysis indicated a systematic increase in surface oxygen concentration from 0 at.% to 31.18 at.% with increasing fluence. Oxygen implantation at 3 × 10¹⁷ ions/cm² resulted in a significant reduction in corrosion current density (I_corr). It is believed that the study paves the way towards improving the corrosion resistance of amorphous alloys by means of the implantation method.

氧离子注入提高锆基非晶合金耐腐蚀性能

腐蚀是造成材料损耗/退化的主要因素之一。研究了锆基非晶合金的抗腐蚀性能。比较了三种酸性介质中原始和注入氧条件下的腐蚀行为。为了研究离子注入对耐蚀性的影响，在3种离子注入速率下进行注入，最高离子注入量（3 × 1017离子/cm2）表现出最好的耐蚀性。利用掠射x射线衍射（GIXRD）、场发射扫描电镜（FESEM）和x射线光电子能谱（XPS）对氧离子注入后结晶相的形貌进行了鉴定和验证。定量能谱分析表明，表面氧浓度从0 at开始系统增加。至31.18%。%，影响力越来越大。在3 × 1017离子/cm2的氧注入下，腐蚀电流密度（Icorr）显著降低。相信本研究为采用注入法提高非晶合金的耐蚀性铺平了道路。
