摘要/Abstract

摘要： 以Ni60为基础材料,La₂O₃为添加物质,通过热喷涂、重熔和冷却复合技术制备了不同La₂O₃含量的Ni60/La₂O₃定向结构复合涂层.研究了复合涂层在3.5 wt.% NaCl溶液中的电化学腐蚀性能和浸泡腐蚀性能,探讨了涂层在3.5 wt.% NaCl溶液中的腐蚀行为.结果表明:涂层在3.5 wt.% NaCl溶液中的腐蚀均表现为活化-钝化-过钝化的过程,随着La₂O₃含量的变化,电荷转移电阻和腐蚀电流密度均先减小后增大.其中La₂O₃为1%的涂层腐蚀电位为－0.543 V,电荷转移电阻为11 791.2 Ω·cm²,腐蚀电流密度为3.775×10^－6A/cm²,涂层表现出最佳的耐腐蚀性能.EDS分析表明,Ni60/1%La₂O₃涂层表面生成由NiO、Cr₂O₃以及La₂O₃等组成的致密均匀钝化膜,有效阻止了NaCl溶液的进一步渗透,使得涂层在3.5 wt.% NaCl溶液中表现出良好的耐蚀性能.

Abstract: A series of Ni60/La₂O₃ directional structural composite coatings with different contents of La₂O₃ were prepared by a combination of thermal spraying, remelting, and cooling techniques, with Ni60 as the base material and La₂O₃ as the additive. The electrochemical corrosion characteristics and immersion corrosion performance of the composite coating in 3.5 wt.% NaCl solution were studied. The corrosion behavior of the coating in 3.5 wt.% NaCl solution was discussed. The results showed that the corrosion of coatings in 3.5 wt.% NaCl solution is an activation-passivation-hyperpassivation process. With the change of La₂O₃ content, both the charge transfer resistance and corrosion current density decrease first and then increase. Notably, the coating containing 1% La₂O₃ demonstrated the most favorable corrosion resistance, with a corrosion potential of －0.543 V, a maximum charge transfer resistance of 11 791.2 Ω·cm², and a minimum corrosion current density is 3.775 × 10^－6 A/cm². EDS analysis showed that the surface of Ni60/1%La₂O₃ coating forms a dense uniform passivation film composed of NiO,Cr₂O₃, and La₂O₃, which effectively prevents the further penetration of NaCl solution. This passivation layer significantly enhanced the corrosion resistance of the coating in 3.5 wt.% NaCl solution.
