可选的，上述颗粒溶液混合循环系统、旋转平台、电泳系统和温控装置均可以与集成控制柜14连接，以便集成控制柜14对上述装置的集成控制。
本发明提供的金属表面改性装置可以进行一种或者多种不同工艺复合的金属表面亲疏水改性处理，可以利用自然沉积法、旋涂法或者电泳沉积法辅助纳米颗粒，在任意平面、曲面、凸台、凹槽等不规则金属表面进行表面处理，使金属表面得到有序的微粒排列，进行表面改性，还可以通过加热设备改变工件表面温度，实现增强纳米级改性颗粒与工件6表面结合力。
在上述实施例的基础之上，上述颗粒溶液混合循环系统包括颗粒溶液混合容器以及振动装置、磁力搅拌装置、悬浮液吸引装置和溶液循环装置中的一个或多个。其中，颗粒溶液混合容器设有向工件提供纳米颗粒溶液的吸引管和吸引管夹具，吸引管用于将纳米颗粒溶液吸引至工件表面。
在上述实施例的基础之上，为了实现上述电泳作用，电泳系统具体包括电泳辅助阴极和电泳辅助系统。其中，电泳辅助阴极用于连接吸引管，电泳辅助阴极的电泳辅助阴极夹具连接机床主轴，机床主轴用于控制电泳 辅助阴极与工件的距离，电泳辅助系统的输出端分别连接电泳辅助阴极和工件。电泳辅助系统输出电压，并分别输送给电泳辅助阴极和工件6。需要说明的是，电泳辅助阴极与工件6之间具有电场，便于纳米级颗粒的沉积。本实施例中采用电泳辅助系统提供电场，能够保证安全和稳定的电场环境。

机床主轴4可以与颗粒溶液混合循环系统2组合，使溶液通过与主轴4连接的吸引管夹具把混合好的溶液从颗粒溶液混合循环系统2吸引至工件6表面，可以一次也可以多次把混合好溶液置于工件6表面。
可选的，可以使若干个工件6与电泳辅助阴极夹具5相组合搭配，并可在线切换不同阴极，也就是切换不同的工件6，从而与不同工件6组成电泳辅助电场，实现电泳辅助沉积。

用于固定工件6的加工槽7安装在微三维运动平台11上，其内安装有工件夹具8可以使待加工工件6安装在加工槽内，进行表面改性加工。微三维运动平台11可以使加工槽7进行准确定向运动，保证加工槽7与主轴4的相对位置，并使加工前溶液准确置于工件6上。

在上述任意一个实施例中，集成控制柜14可以放置在机床的工作台1右侧，集成控制柜14中集成了本发明所述所有系统的控制程序，可以保证本发明所述所有工艺的运行。
在上述任意一个实施例中，根据具体需要的加工工艺需要，先把需要的纳米颗粒置于颗粒溶液混合循环系统2里进行充分混合，然后把待加工金属工件6置于加工槽7内，并用工件夹具8夹紧，通过集成控制柜14控制微三维运动平台11和机床主轴4，把溶液置于工件6上，可以通过电 泳辅助系统12形成辅助电场，进行表面改性加工。同时可以控制活动掩膜与工件6的相对位置，并保证加工过程中，活动掩膜与工件6相互压紧，以加工工件局部区域表面不同形状，不同位置的表面改性效果。另外，还可以通过旋转控制系统10实现颗粒的旋涂沉积法。
加工过程中可以通过CCD在线监测系统3对其进行观测，然后把工件6置于真空及温度控制系统13，进行加热处理，控制加工条件，最终达到金属工件6的表面亲疏水改性。
除了上述各个实施例所提供的金属表面改性装置的主要结构，该金属表面改性装置的其他各部分的结构请参考现有技术，本文不再赘述。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
