看着大街上带着镀金饰品的人群越来越多，镀金的花样和式样的装饰品不断更新，为单调的生活平添了许多亮丽的颜色。

那么，镀金是一种什么的技术呢?在生活中用到的镀金技术与我们经常带的镀金饰品采用的技术是一样的吗?带着这些疑问，我还开始关注起了有关镀金、镀银以及镀钛技术的一些报道。发现镀金、镀银、镀钛采用的技术大体是一样的，总的来说都是一种电镀技术，利用专门的化学方式，像电解等方法，把一中比如金、银或者钛安在其他的不是同一种金属上面，通过电形成一层薄薄的膜层。

具体说来，镀金就是先把金汞弄成薄薄的一层先镀上去，然后利用电进行加热让汞挥发后，把金子放在金属或者是其他想要镀金的物体的表面，这样就可以镀上了一层金。

而镀钛呢，技术虽然与镀金、镀银有着相同之处，但是由于钛的本身特质决定，镀钛实际上是在物体的表面利用电的化学办法镀上了一层钛膜，它与我们常说的水镀差不多。听说镀钛采用的水镀工艺就是我们比较熟知的电镀工艺。据说，电镀工艺霸占了很长时间的镀膜工艺市场，主要因为它本身具有的毒性大，因此市场才逐渐缩小。现在使用的镀钛工艺，都是继承了原有电镀工艺比较好的优点，像耐磨性、外表光亮等，与此同时也改变了电镀工艺自身的有毒特性。所以镀钛工艺目前很受欢迎，都在于它的无毒性，还有它的环保特性。

Looking at the streets with gold-plated ornaments of the crowd more and more, gold-plated patterns and style of decoration update, for the monotonous life added a lot of bright color.

So, what kind of technology is gold plating? Is the gold-plating technology used in life the same as the gold-plating jewelry we often wear? With these questions in mind, I also began to pay attention to some reports about gold, silver and titanium plating technology. Found that gold plating, silver plating, titanium plating technology is generally the same, in general is a kind of electroplating technology, the use of special chemical methods, such as electrolysis and other methods, such as a gold, silver or titanium in the other is not the same metal above, through electricity to form a thin film layer.

To be specific, gold plating is to make a thin layer of mercury gold and then coat it, and then heat it electrically to evaporate the mercury, and then put the gold on the surface of the metal or other object that you want to gilt, so that you can coat it with gold.

And titanium plating, although the technology and gold plating, silver plating has the same place, but because of the characteristics of titanium itself, titanium plating is actually on the surface of the object using electric chemical method on a layer of titanium film, it and we often say water plating. I heard that titanium plating using water plating process is we are more familiar with the plating process. It is said that the plating process has occupied the film plating process market for a long time, mainly because of its own toxicity, so the market is gradually shrinking. The titanium plating process used now inherits the advantages of the original plating process, such as wear resistance, bright appearance, etc., but also changes the toxic characteristics of the plating process itself. So titanium plating process is very popular, all lies in its non-toxic, and its environmental characteristics.
