研究了温度、时间、浓度等对 A3钢片上 Ni-P-Zn3(PO4)2、 Ni-P-ZnSnO3和 Ni-P-ZnSiO3纳米复合化学镀层外貌的影响。用扫描电子显微镜（ SEM）观察外貌；称重法测定厚度；通过 10％ NaCl溶液、 1％ H2S气体加速腐蚀试验、 10％ CuSO4溶液点滴试验等多种手段测定其耐腐蚀性能；用 X-射线光电子谱 (XPS)及俄歇电子能谱 (AES)测定其价态及组成。结果表明：在最佳施镀条件下，可得光亮、致密、耐腐蚀性强于 A3钢、磷化膜及 Ni-P镀层的纳米复合化学镀层。镀层的原子百分组成约为 (％ )： Ni-P-Zn3(PO4)2： Ni 70.00,P 12.47,Zn3(PO4)2 13.93,C 3.6； Ni-P-ZnSnO3： Ni 77.56,P 10.00,ZnSnO3 9.84,C 2.6； Ni-P-ZnSiO3： Ni 83.00,P 10.96,ZnSiO3 5.15,C 0.89。
The effects of temperature, time and concentration on the appearance of Ni-P-Zn3 (PO4) 2, Ni-P-ZnSnO3 and Ni-P-ZnSiO3 nanocomposite coatings on A3 steel were investigated. The appearance was observed with a scanning electron microscope (SEM); the thickness was measured by a weighing method; the corrosion resistance was measured by 10% NaCl solution, 1% H2S gas accelerated corrosion test and 10% CuSO4 solution drop test; Photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) determination of valence and composition. The results show that under the optimum conditions of plating, the nanocomposite coatings with bright, dense and corrosion resistant properties are better than those of A3 steel, phosphate coating and Ni-P coating. The atomic percent composition of the coating is about (%): Ni-P-Zn 3 (PO 4) 2: Ni 70.00, P 12.47, Zn 3 (PO 4) 2 13.93, C 3.6; Ni-P-ZnSnO 3: Ni 77.56, P 10.00, ZnSnO3 9.84, C 2.6; Ni-P-ZnSiO3: Ni 83.00, P 10.96, ZnSiO3 5.15, C 0.89.
