- 研究了磷化时间对建筑结构钢表面锌钙系磷化膜的厚度、化学成分和耐蚀性的影响，并对锌钙系磷化膜的物相结构进行了分析。结果表明：随着磷化时间延长，磷化膜厚度逐渐增加，但达到一定限度后基本不变。在不同磷化时间下获得的 6 种磷化膜的化学成分均为 Zn 、 Ca 、 P 、 O 和 Fe 元素， Zn 、 Ca 和 P 的质量分数随着磷化时间延长均呈现先升高后下降的趋势，而 Fe 的质量分数显著下降后基本不变。 6 种磷化膜的耐蚀性存在一定差异。磷化 24 min 获得的磷化膜厚度达到 8.1 μ m ， Zn 、 Ca 和 P 的质量分数均达到最高，分别为 34.78 % 、 7.74 % 、 17.15 % ，电荷转移电阻和低频区的阻抗值分别达到 1937 Ω ·cm 2 、 1157 Ω ·cm 2 。该磷化膜的主要物相为 CaZn 2 （ PO 4 ） 2 ·2H 2 O ，耐蚀性相对较好。
- Abstract:
- ： The effect of phosphating time on the thickness ， chemical components and corrosion r esistance of zinc-calcium phosphating films on the surface of building steel was studied ， and the phase structure of zinc-calcium phosphating film was also analyzed. The results showed that with the extension of phosphating time ， the thickness of phosphating films increased gradually ， but it remained nearly unchanged after reaching a certain limit. The chemical components of six phosphating films obtained at different phosphating time were all composed of Zn ， Ca ， P ， O and Fe. The mass fraction of Zn ， Ca and P all showed a trend of first increasing and then decreasing with the extension of phosphating time ， while the mass fraction of Fe remained nearly unchanged after a significant decrease. There was a significant difference between the corrosion resistance of six phosphating films. The thickness of phosphating film obtained by phosphating for 24 min reached 8.1 μ m ， and the mass fraction of Zn ， Ca and P reached 34.78 % ， 7.74 % and 17.15 % respectively. The charge transfer resistance and low f requency area impedance value reached 1937 Ω ·cm 2 and 1157 Ω ·cm 2 ， respectively. The main phase of the phosphating film was CaZn 2 （ PO 4 ） 2 ·2H 2 O ， and its corrosion resistance was relatively good.
