1. The anticathode of polarization curve of carbon steel with SAMs by changed- electrical voltage method suggested that carbon steel is passivation state in the rust medium.

2. The mechanism is made up of alloy, Anticathode surface treatment, easy installation and adjustment.

3. The surface is treated by anticathode oxidation which greatly improves the rigidity and anti - corrosion.

4. The influence of the distances between anticathode and cathode and electrolysis voltages on dimples was investigated.

5. Extruded aluminum alloy cylinder body or cast steel, The surface is treated by anticathode oxidation which greatly improves the rigidity and anti-corrosion.

6. By building the data ware house and using on line analysis process, engineer can analysis the cathode and anticathode from different view.
