【Abstract】 The performance of galvanic corrosion resistance of several new grounding materials widely used in China were studied by comparison of solution accelerated corrosion test and accelerated galvanic corrosion test. The solution accelerated corrosion rates and the galvanic accelerated corrosion rates of these grounding materials were compared in acid-base property environment. The results show that stainless steel, high-silicon ferrochrome and carbon nano modified materials had good corrosion resistance in acidic environment, and the galvanic accelerated corrosion rate of high-silicon ferrochrome was the least. In alkaline environment, stainless steel, high silicon ferrochrome and graphene composite had good corrosion resistance, and the galvanic accelerated corrosion rate of graphene composite was the least. In neutral environment, both stainless steel and high silicon ferrochrome had good corrosion resistance, and the stainless steel had better galvanic corrosion resistance.更多还原
