6.根据权利要求1所述的水龙头表面处理方法，其特征在于，所述PVD镀色步骤包括：
a.将待镀产品传入装有金属靶材的镀膜腔室，开启泵抽真空及加热装置进行基底-3加热，使得本底真空达到1×10Pa及达到80-150℃工艺温度后，向腔室通入10-1000sccm的氩气，启动溅射电源，设置溅射功率1-15KW，镀膜时间10-300S，得到厚度为1-100nm的金属膜层；
b.将镀完金属膜层的产品传入装有可形成低折射率膜层的靶材镀膜腔室，加热达到80-150℃的工艺温度，向腔室通入工艺气体，设置溅射功率1-15KW，镀膜时间1-300S，得到厚度为1-100nm的低折射率膜层；
c.将镀完低折射率膜层的产品传入装有可形成高折射率膜层的靶材镀膜腔室，加热达到80-150℃的工艺温度，向腔室通入工艺气体，设置溅射功率1-15KW，镀膜时间1-300S，得到厚度为1-100nm的高折射率膜层；
交替进行步骤b及步骤c，以交替镀上所述低折射率膜层及所述高折射率膜层。
7.根据权利要求1所述的水龙头表面处理方法，其特征在于，所述封釉步骤包括为：
a.清洗：将水龙头放入清洗烘干机进行清洗，并快速烘干；
b.釉料涂布：将水龙头进行釉料涂布和常温流平，釉料涂布使用的釉料含有助剂水性耐磨剂和氧化硅；
c.釉料烘干：将水龙头送入烘干炉进行烘烤，使釉料固化；
d.冷却：将水龙头静置、冷却。
