镀铬的

The traditional chromium plating has carried through according to the technology of Sargent.

由于Sargent电镀铬工艺存在阴极电流效率低，分散能力和深镀能力差，以及六价铬离子带来的对操作工人身体的危害和严重的环境污染等问题，近年来发展了三价铬电镀工作。

It was recognized that a simple chromate treatment of galvanized products results in the production of a passive film on the surface of zinc coating which inhibits white rust formation.

热浸镀锌镀件上为了防止白锈，一般以铬酸盐处理在表面形成保护膜来抑制白锈的生成。

X-ray photoelectron spectroscopy was used to investigate the content and chemical valence of chromium element,and the content of compounds in chromate passive film formed on commercial tinplate via a cathodic electrolytical treatment.

用X射线光电子能谱(X-ray photoelectron spectroscopy，XPS)分析的方法，对铬酸盐钝化镀锡钢板的正常表面及缺陷点处铬元素的含量、价态以及由铬元素组成的化合物进行了研究。

From the phenylethylene additives'sulfur are chrome-plated wave of chromium hardness likely higher than normal.

从含不无机添增剂的铬镀波洋获得的铬软度有不定比别致的更矮。

While chromium may stably exist in either the passive or active state, small amoullt additioll of palladium significantly increases the corrosion resistance of chromium plating in deaerated 5% and 20% sulfuric acid solutions in consequence of spontaneous passivation.

极化曲线和阻抗频谱测定表明，在相应铬镀层处于活化－钝化过渡的电位区间，含钯镀层都表现出净阴极电流；活化溶解与钝化过程随电位的相对发展变化可由低频段容抗圈的演变来推定。

The only difference was that the total content of Cr in passivated film on electrodeposited zinc alloys was higher.

它们的区别在于：合金镀层钝化膜中总铬量较高，膜层完整、致密，镀层/钝化膜界面存在铁系金属的富集层，这是锌基合金镀层钝化膜具有高耐蚀性的主要原因。

First increased the built-up welding internal mixer special-purpose flinty antifriction metal in Gao Moqu, and in plates the 0.20mm thick hard chromium level with the sizing material contact active face, compared to domestic other company product coating accumulation one time, thus the service life obtains the big extension.

首先在高磨区增加了堆焊密炼机专用硬质耐磨合金，并在与胶料接触的工作表面均镀0.20mm厚硬铬层，比国内其他公司产品镀层增厚一倍，从而使用寿命得到大大延长。

It also was studied to increase the corrosion resistance of blue-white passivation film of zinc plating on the premise of not improving the chromium content in plating.

介绍了如何提高镀锌低铬蓝白钝化的耐蚀性能，探讨了在不提高钝化膜含铬量的前提下，增加镀锌层蓝白钝化的耐蚀性能。

This paper mainly introduced present situation of study zinc chrome coat, the composition of coat liquid, technological characterstics and advntages to be compared with conventional plating and hot plating technics.

锌铬膜涂层的优良耐蚀性能、环境友好、无氢脆性、涂层均匀等特点得到了广泛的应用。介绍了锌铬膜的研究现状、涂液组成、工艺特点及与传统电镀、热镀工艺相比的先进性等

Strong in its fashion appeal, this two-toned necklace with pale gold and ruthenium plating sparkles with an array of multi-coloured bezel set crystals.

引人瞩目的时尚造型，灵感源自立体派装饰艺术，镀淡金色和镀黑铬色项链搭配含多种颜色的包边镶嵌水晶。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
