中文摘要:
      采用超声-电沉积法,在20# 钢上制备Ni-纳米Al2O3复合镀层。通过将试验样片恒温25℃静态全浸泡在PH=3.5、浓度5% 的NaCl溶液中浸泡210h的方法,研究脉冲电流密度、脉冲占空比、超声波功率、纳米Al2O3颗粒浓度等工艺参数对纳米复合镀层耐蚀性能的影响。利用扫描电镜(SEM)观察复合镀层表面形貌及测量复合镀层的断面厚度;利用理学D/ max 2400 型X 射线衍射仪(XRD)确定镀层中含有第二相纳米Al2O3粒子
英文摘要:
      Ni-nanoAl2O3 composite coatings were prepared on the 20 steel substrates by ultrasonic-electrodeposited technology. Through the method of the samples constant temperature 25℃ were statically and entirely dipped in the PH=3.5、5% NaCl solution lasting 210h, the effects of pulse current density, duty ratio of pulse, ultrasonic waves, and nanoAl2O3 concentration on the corrosion resistance of nano-composite coatings were deeply studied. Surface morphology and thickness of composite coating were observed and measured by SEM; nano-Al2O3 was ascertained by XRD.
