中文摘要：
采用表面机械研磨处理（Surface Mechanical Attrition Treatment,SMAT）技术实现了Cu-10%Ni的表面纳米化。采用X射线衍射仪（XRD）、场发射扫描电镜（SEM）、能量色散谱（EDS）等研究了表面纳米化Cu-10%Ni合金在酸性硫酸钠溶液（0.05 mol/L Na2SO4＋0.05 mol/L H2SO4）的电化学腐蚀行为。结果表明：原始Cu-10%Ni合金和表面纳米化合金在腐蚀介质中的极化曲线均有钝化现象产生;但表面纳米化处理之后的合金的耐蚀性下降了,腐蚀速率加快了;且合金的腐蚀性能随着表面纳米化时间的延长逐渐降低。
英文摘要：
By means of surface mechanical attrition treatment （SMAT）,a nanostructured surface layer was formed on Cu-lOwt% Ni plate.XRD （X-ray diffraction）, SEM （scanning electron microscope ）, EDS （energy -dispersive spectroscopy）technique were used to experimentally investigate the electrochemical corrosion behavior of surface nanocrystallization Cu-10wt%Ni alloy in acid sodium sulfate solution （0.05 mol/L Na2SO4 ＋ 0.05 mol/L H2SO4）.The experiment results showed that the Cu-lOwt%Ni alloy with surface nanometer crystallization had lower corrosive resistance than the coarse Cu-10wt%Ni alloy.And the corrosion rate became faster than the original coarse sample.As the treatment time prolonged, the corrosion property of the Cu-10wt%Ni alloy decreased gradually.
