- Title:
- Study on acid corrosion resistance of gray cast iron and carbon steel
- Keywords:
- In this paper; boronitriding; a method of chemical heat treatment; was used to change the chemical composition of the surface layer of carbon steel and cast iron; improve the structure of the surface layer and increase the electrode potential; so as to obtain the acid-resistant corrosion layer.Through a series of heat treatment process; acid corrosion resistance test and metallographic analysis; the best boronitriding agent formulation and treatment process were determined.When the flake graphite size of gray cast iron is less than grade 4; the acid corrosion resistance of gray cast iron can be significantly improved by boronitriding.Ordinary carbon steel after treatment; at room temperature; can withstand different concentrations of hydrochloric acid; sulfuric acid corrosion.Therefore; under appropriate conditions; it can be used to replace some stainless steel and save the rare nickel-chromium alloy.
