Introduction: Hand Polish “gold Pen” With Only a Polish Stick 通过打磨获得金色签字笔
You can make a golden pen with only a polish stick and a normal plastic pen with a silver electro plating penhead.Everyone can make it.
Description：This tutorial was written in Chinese and English.If there is conflicts between English and Chinese.English subject to chinese..
仅仅需要一根抛光条和一只普通的塑料中性笔。每个人都可以做到。

Step 1: What You Need 材料清单
What you need：some signing pens、a two-side polishing block
The white side of the two-side polishing stick is very smooth,it is used for polishing.The green side is the rough side,it is used for bruthing
所需材料：签字笔若干、双面抛光块一个
双面抛光条两面都可以用，其中白色面光滑，用于抛光。绿色面粗糙，用来打磨。

Step 2: Remove the Silver Layer 除去银色镀层
step one：Remove the silver layer，and you will get a golden layer.It is copper matiarial.
第一步：除去银色电镀层，得到金色外观说明：使用绿色粗糙面纵向打磨笔头部位，得到金色的镀铜层。横行打磨效率很高，但是容易把镀铜层磨去，需谨慎使用。
Step 3: Polish the Copper Layer 抛光镀铜层
The second step：Use the smooth side to polish the copoer layer，and you can get a golden mirror face.
第二步：使用白色光滑面抛光镀铜层，可以得到金色镜面效果
Step 4: Remove the Copper Layer 除掉镀铜层
step three：Use the rough side to remove the copoer layer，you will found that it is plastic.
第三步：使用绿色粗糙面打磨掉镀铜层，你会发现笔头其实是塑料材质
Step 5: Polish the Plastic 抛光塑料
The fourth step：use the smooth side to polish the plastic
第四步：使用白色面来抛光塑料
Step 6: Extend 延伸
Principle：the pen head is plastic，the golden layer is copper，the silver layer maybe silver、chrome 、nickel or other metal.
In order to get better quality of electroplating a layer，some（not all）matiarial should electroplate a copoer layer first.then electroplating a chrome 、nickel or other metal layer onto the copoer layer.
Corrosion and rust：As copper is eazy to corrosion，the golden pen head will change color.This is a normal phenomenon.But you can patina it to get a special color.There are many tutorials on the internet.Maybe I'll make a tutorial later.
原理：笔头材质是塑料，金色和银色的金属都是电镀上去的。金色镀层是铜，银色镀层可能是银、铬、镍或其他金属。
为了提高镀层的结合力，使镀层更牢固，有些（不是全部）工件在电镀前需要先镀一层铜，再在镀铜层上镀其他金属
腐蚀与生锈：由于铜容易腐蚀，金色笔头一段时间后容易变色发黑，这属于正常现象。不过也可以使用一些人工做旧工艺来得到一些特殊颜色的氧化层。以后有机会再介绍吧
