摘要
文章采用磁控溅射法在15-15Ti钢表面沉积Ti/TiN/SiC功能梯度薄膜,并用X射线衍射仪(X-ray diffraction,XRD)、场发射扫描电子显微镜(field emission scanning electron microscope,FESEM)和原子力显微镜(atomic force microscope,AFM)表征薄膜的结构和形貌,并研究了镀膜15-15Ti钢在Pb-Bi合金溶液中的耐腐蚀性能。结果表明,镀膜后的15-15Ti钢在Pb-Bi合金溶液腐蚀后表面无Fe_3O_4氧化层出现,其耐腐蚀性能得到提高。
The Ti/TiN/SiC functionally gradient films were prepared on 15-15 Ti steel by magnetron sputtering. The structures and morphologies of the thin films were measured by X-ray diffraction(XRD), field emission scanning electron microscope(FESEM) and atomic force microscope(AFM). The corrosion resistance of the 15-15 Ti steel coated with SiC layer in Pb-Bi alloy solution was also studied. The results show that there are no Fe_3O_4 oxide products on 15-15 Ti steel coated with SiC layer after corrosion for 1 000 h in the Pb-Bi alloy solution, so the corrosion resistance of 15-15 Ti steel is improved.
