中文摘要:
      研究了用电刷镀在Q235钢上制备出Ni-TiO2 纳米复合镀层复合镀液中,纳米颗粒的加入量及不同的表面活性剂对镀层性能的影响。采用SEM 对复合镀层的表面形貌进行分析,用极化曲线研究了纳米复合镀层在NaCl溶液中的腐蚀电化学行为,结果表明:与纯Ni镀层相比,Ni-TiO2 纳米复合镀层晶粒更加细小,空隙率更低,阳离子表面活性剂分散镀液所得镀层效果最为显著;复合镀液中纳米TiO2 质量浓度为10g/L时,复合镀层的耐腐蚀性能最优;纳米颗粒含量相等的情况下,阳离子表面活性剂分散镀液所得镀层具有最好的耐腐蚀性能。
英文摘要:
      It mainly investigated the impact of various contents of TiO2 nanoparticles and different surfactants in nanocomposite plating bath on the performance of Ni-TiO2 nanocomposite coating, which were prepared on Q235 lowcarbon steel by electro-brush plating. The surface microstructure of composite coatings was studied by SEM. Thecorrosion electrochemical behavior of Ni-TiO2 nanocomposite coating in NaCl solution was studied by polarization curve. The results show that Ni-TiO2 nanocomposite coatings have smaller grain and lower porosity compared to pure Ni coating. The best coating was made by cationic surfactant to disperse bath. While TiO2 nanoparticle content was 10g/L in plating bath, the coating had the best corrosion resistance. And the coating had the best corrosion resistance by cationic surfactant to disperse bath while plating bath have the same TiO2 nanoparticle content.
