Abstract: The silicon alloy of aluminum is the outstanding energy storage metal material,but it has stronger corrosion of container materials used for putting the alloy.0Cr25Ni20 stainless steel was used as the sill of container materials under the circular conditions of 620 ℃ and 520 ℃ for a long time.In order to further slow down corrosion,the graphite powder,TiB2,the organic resin were used as 3 kinds of heat coatings of main composition.The experimental result indicates that the coating can inhibit th...
