摘要:
为评估无氰镀锌工艺在航空零部件中的适用性，对无氰镀锌试样进行了中性盐雾试验、酸性盐雾试验、酸性大气试验、周浸腐蚀试验及湿热试验，并与传统氰化镀锌工艺进行对比。结果表明：无氰镀锌经钝化后处理的试样在中性盐雾试验720h内未出现红锈，在酸性盐雾试验480 h内未出现红锈。无氰镀锌经钝化后处理的试样在周浸腐蚀试验120 h后腐蚀等级为 3级，优于氰化镀锌经钝化后处理试样的7级。无氰镀锌试样在酸性大气试验4个循环后仅出现轻微变色，未出现白锈或红锈。无氰镀锌试样在湿热试验15个循环后仅出现少许点状白锈，未出现红锈。研究结果表明，无氰镀锌工艺在耐腐蚀性能方面优于或等同于传统氰化镀锌工艺，适用于航空零部件的表面防护处理。
Abstract:
To evaluate the applicability of cyanide-free zinc plating in aviation components, neutral salt spray tests, acid salt spray tests, acid atmosphere tests, periodic immersion corrosion tests, and damp heat tests were conducted on cyanide-free zinc-plated samples, with comparative analysis against traditional cyanide zinc plating processes. The results show that passivated cyanide-free zinc-plated samples exhibit no red rust within 720 h in neutral salt spray tests. Passivated cyanide-free samples show no red rust within 480 h in acid salt spray tests. In periodic immersion tests, passivated cyanide-free samples achieve a corrosion grade of 3 after 120 h, outperforming the grade 7 of passivated cyanide-plated samples. Cyanide-free samples display only slight discoloration without white/red rust after four acid atmosphere test cycles. After 15 damp heat test cycles, cyanide-free samples develop only minor spot-like white rust with no red rust. The study demonstrates that the cyanide-free zinc plating process exhibits equal or superior corrosion resistance compared to traditional cyanide processes, making it suitable for surface protection of aviation components
