活化：使金属表面钝化状态消失的作用。
Activation: the metal surface passivation state disappear role.
在表面上刷钝化剂15分钟，保持表面潮湿。
Brush passivating agent on surface very 15 minutes, maintain a wet surface.
这些气泡聚集在工件表面上阻碍了钝化作用。
These bubbles collect on the surface of the work piece and interfere with passivation.
此外，钝化剂减少燃料电池系统的表面腐蚀。
In addition, the passivator reduces the surface corrosion in the fuel cell system.
