Study on the Corrosion of Cast Iron Material in Salt Lake Brine

The corrosion of four kinds of iron and steel in Qinghai salt lake brine is tested. The morphology and composition of covering and corrosion products formed on the gray cast iron surface are determined. The effects of salt lake brine and corrosion products on cast iron corrosive nature are analyzed. The corrosion of gray cast iron has the typical graphitization phenomenon and the reticular framework layer formed during the test can reduce...
