应用钛离子注入以改良铅和铅锑合金在5mol/L的H2SO4中的抗腐蚀能力。用阶跃电位法测定的腐蚀电流和电子显微镜观察的表面腐蚀形貌来描述腐蚀行为。讨论了钛离子注入时离子的加速能量对腐蚀行为的影响。认为钛离子注入对铅的氧化和氢气的析出这两个过程有不同的作用。钛在铅和铅锑合金表面层中存在的深度范围和分布情况决定子离子的加速能量,离子的加速能量直接影响着腐蚀性能的改良。
Titanium ion implantation is used to improve the corrosion resistance of lead and lead-antimony alloys in 5 mol / L H2SO4. Corrosion behavior is described by the corrosion current measured by the step potential method and the surface corrosion morphology observed by electron microscopy. The effect of ion acceleration energy on corrosion behavior is discussed. Titanium ion implantation that the oxidation of lead and hydrogen evolution of these two processes have different roles. The depth and distribution of titanium present in the surface layers of lead and lead-antimony alloys determine the accelerating energy of the daughter ions. The acceleration energy of the ions directly affects the improvement of the corrosion behavior.
