Moreover, the pre-treatment and post-treatment processes for the steel sheet subject to continuous zinc plating were also discussed. Results showed that the alkaline zincate plating process had many advantages over conventional alkaline cyanide zinc plating process, including high current efficiency, good throwing power, and strung adhesion strength of the coating.

结果表明，该工艺电流效率高（锌离子含量16~24g/L时，电流效率可提高约20%，镀液均镀能力好（宽度为1m的镀锌薄板，中心点厚度与边缘厚度差不大于10%，镀层结合力优良（将试片180°任意弯曲，镀层无起皮、剥落现象；在烘箱中加热至180-200℃，保温60min，冷水中急剧冷却，镀层无突起、鼓泡、剥落现象），所镀得的镀锌薄钢板适合于钝化和彩涂等后处理。

In addition, there are bond areas between the new and the primary coverage because of the growing up of the plating coat, which may lead to the emergence of micro crack on the coating owing to such causes as too big or uneven impact during plating process, little distortion of global granular zinc dust inside the plating coat, less tight coalescence of the zinc dust flecks.

由于形成镀层的过程处在酸性环境，在镀层增厚过程中不可避免把酸性溶液包裹在镀层里面，酸性溶液会与金属基体和镀层反应，产生氢气，必然会寻找通道选出，形成微气孔；镀层是逐渐形成的，新生镀层与原有镀层之间存在结合面；镀覆过程由于撞击力过大或者不均匀，镀层内部球形颗粒状锌粉变形较小，球形颗粒与球形颗粒的结合不严密等，这些原因会导致镀层产生微裂纹。

The results show that complexing agent greatly effects on film's density. For the double complexing agents solution system based on citric acid, the solution with lactic acid and citric acid produced most compact film with lowest porosity; and for the double complexing agents solution system based on butane diacid, the solution with butane diacid and malic acid made most compact film with lowest porosity.

研究结果表明：络合剂对镀层的致密度影响显著，对于以柠檬酸为基的双络合剂体系镀液来讲，乳酸-柠檬酸双络合剂体系镀液获得的镀层致密度最好，具有最低的气孔率；而对于以丁二酸为基的双络合剂体系镀液来讲，丁二酸-苹果酸双络合剂体系镀液获得的镀层致密度最好，具有最低的气孔率。

The pore distribution in the direction of coating thickness was self-existent and could not join to intercommunicating pore.The pore diameter was very tiny so that it could prevent hydrotropic solution entering into the pore.

机械镀锌的形层过程既没有热镀锌那样的高温冶金反应，也没有电镀锌那样的电沉积效应，镀层是常温常压下利用化学吸附沉积和机械碰撞使金属锌粉在工件表面镶嵌堆积而成[1]，所以人们认为机械镀锌镀层的致密性要低于电镀和热镀锌镀层，但机械镀锌镀层又表现出良好的耐腐蚀性能。

87款有了变化，首先占车体大半部分设计的机器从原来的黑色加以了镀铝和镀铬的设计，进气道、侧盖、后尾灯罩都涂以黑色，不过前避震部分却是银色的，还有注意看前轮毂；比之85、86款前轮毂由5根支撑形式改为了碟式支撑，并一直沿用至今，这样一来，87款最大的特色是车前部分显得更为强悍了。

It is found that the structure of the ternary electroless Ni-W-P coating is greatly influenced by W content in the deposit. It is also found that the requisite content of phosphorus for amorphous Ni-W-P structure is less than that of Ni-P binary alloy coating, and the more tungsten exists, the less phosphorus is required. The hardness of the deposits will be enhanced as the deposit structures are changed from amorphous to mix-or nanocrystalline structures. The corrosion resistance of Ni-W-P ternary alloy is improved as W content increased, and the passivation of amorphous deposits is formed more easily than that of mix-structure and nanocrystalline deposits.

研究发现，化学镀Ni-W-P三元合金镀层的结构受镀层中钨含量的影响较大，非晶态Ni-W-P三元合金镀层所需磷含量较非晶态Ni-P二元镀层所需磷含量要低，并且钨含量越高，所需磷含量越少；镀层硬度随镀层结构从非晶态→混晶态→纳米晶态转变而增加；镀层的耐蚀性随镀层中钨含量增加而变好，且非晶态镀层较混晶态和纳米晶态镀层更易形成钝化区。
