- 摘要:
- 为了解决镁合金耐蚀性差的问题，通过向钙系磷化液中添加少量硝酸铈以获得高耐蚀的磷化层。采用 SEM 、 XRD 、 EDS 对磷化层进行形貌和成分的表征，采用极化曲线和浸泡析氢实验对磷化层的耐蚀性进行测定。结果显示，磷化层的主要组成为 CaHPO 4 ·2H 2 O ，硝酸铈的添加不影响磷化层的成分。当硝酸铈的加入量为 100 mg·L -1 时，所得的磷化层结晶细且致密，磷化层厚度均一（约 26 μ m ）。磷化层在 3.5 % 氯化钠溶液中的腐蚀电流密度为 1.4×10 -6 A·cm -2 ，浸泡 165 h 时，析氢量为 0.6 mL·cm -2 。与基底及未添加硝酸铈的磷化层相比，添加硝酸铈的磷化层耐蚀性有所提升。
- Abstract:
- ： To solve the problem of poor corrosion resistance of the phosphating layer on Mg alloy ， a small amount of cerium nitrate was added to the calcium-based phosphating solution to obtain a phosphating layer with high corrosion resistance. The morphology and composition of the phosphating layer were characterized by SEM ， XRD ， and EDS ， and the corrosion resistance of the phosphating layer was measured by polarization curve and immersion hydrogen evolution experiment. The test results showed that the main composition of the phosphating layer is CaHPO 4 ·2H 2 O ， and the addition of cerium nitrate does not affect the composition of the phosphating layer. When the addition amount of cerium nitrate is 100 mg·L -1 ， the obtained phosphating layer has fine and dense crystals ， and the thickness of the phosphating layer is uniform （ about 26 μ m ） . The corrosion current density of the phosphating layer in 3.5% NaCl solution is 1.4×10 -6 A·cm -2 ， and the hydrogen evolution amount is 0.6 mL·cm -2 when it is soaked in NaCl solution for 165 h. The corrosion resistance of the phosphating layer with cerium nitrate added is improved when compared with the substrate or the phosphating layer without cerium nitrate added.
