Abstract

Nickel phosphorus alloy coatings were prepared by electrodeposition route from sulfate electrolyte bath at various current densities. SEM studies revealed that spherical grains covered the entire surface with uniform distribution. EDX results showed a linear increase of P content in the developed deposits with current density, causing an increase in the grains size and a drop in hardness values. XRD studies revealed monocrystalline orthorhombic alloys at low phosphorus content (10.88 wt. %). Corrosion test results showed that 1 A.dm-2 is the best applied current density providing the nobler Ecorr (-171.4 mV) and the lower icorr (4.64 μA/cm2).

不同电流密度下电沉积纳米晶NiP合金涂层的表征

以硫酸盐浴为原料，在不同的电流密度下，采用电沉积方法制备了镍磷合金镀层。SEM研究表明，球形晶粒以均匀分布的方式覆盖整个表面。EDX结果显示，随着电流密度的增加，已开发沉积物中的P含量呈线性增加，导致晶粒尺寸增加和硬度值下降。XRD研究揭示了低磷含量（10.88wt.%）的单晶正交合金。腐蚀试验结果表明，1A.dm-2是最佳的外加电流密度，可提供更高的Ecorr（-171.4 mV）和更低的icorr（4.64μA/cm2）。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
