- 摘要:
- 选用Q345钢作基体制备SiC颗粒掺杂锌钙系磷化膜（DPF），研究其微观形貌、成分、厚度及耐腐蚀性能，并与普通锌钙系磷化膜（CPF）进行比较。结果表明：DPF和CPF都完全覆盖Q345钢表面，厚度比较接近，但DPF晶粒间的缝隙被SiC颗粒填充。CPF由Zn、O、P、Ca、Fe和C元素组成，而DPF由Zn、O、P、Ca、Fe、C和Si元素组成。DPF和CPF都能降低Q345钢的腐蚀倾向和腐蚀速率，明显提高Q345钢的耐腐蚀性能。与CPF相比，DPF具有更好的耐腐蚀性能，其腐蚀电流密度较Q345钢降低了近一个数量级，极化电阻最高，接近于8.30 kΩ·cm2，对Q345钢的保护效率达到92.5%且腐蚀后表面仍然较为平整，主要归因于DPF晶粒间的缝隙被SiC颗粒填充，对腐蚀溶液具有较强的阻挡能力，从而抑制腐蚀的发展。
- Abstract:
- The zinc-calcium phosphate film doped with SiC particles （DPF） on Q345 steel was prepared, and its microstructure, composition, thickness and corrosion resistance were investigated and compared with that of ordinary zinc-calcium phosphate film （CPF）. The results showed that DPF and CPF with approximate thickness and were completely cover the surface of Q345 steel, but the holes and gaps between the grains of DPF were filled with SiC particles. CPF was composed of Zn, O, P, Ca, Fe and C, while DPF was composed of elements Zn, O, P, Ca, Fe, C and Si. Both DPF and CPF can reduce the corrosion tendency and corrosion rate of Q345 steel, and obviously improve the corrosion resistance of Q345 steel. The corrosion current density of DPF decreased nearly one order of magnitude compared with that of Q345 steel , the polarization resistance nearly 8.30 kΩ·cm2, the protection efficiency to Q345 steel reached 92.5% and the surface was relatively flat after corrosion. DPF exhibited better corrosion resistance than that of CPF, which was attributed to that the holes and gaps between the grains of DPF were filled with SiC particles, the penetration of corrosion solution was hindered, thus inhibiting the development of corrosion.
