Abstract
In view of the problems of metal grounding material, including non-corrosion resistance, poor combination with soil, easy to steal and so on, a kind of composite grounding material with the modified silicate cladded carbon steel is developed, which takes the corrosion resistance of modified silicate material and the good conductivity of metal into account. By simulating the corrosion tests in the environments with different pH value, the results show that in the soil with different pH value, the modified silicate can protect the carbon steel well, and its anti-corrosion effect is better than that of the galvanized steel; in the soil with pH = 5, its anti-corrosion effect is better than that of copper; in the soil with pH = 9, its anti-corrosion effect is better than that of copper plated steel. The modified silicate composite grounding material has obvious corrosion resistance in both acid and alkaline soil.
