; Abstract: Golden yellow rare earths chemical conversion coating was obtained on the surface of magnesium alloy by immersing in cerium sulfate solution. The corrosion... Analysis and discussion In cerium sulfate solution, many micro-batteries form on the surface of magnesium alloy sample because of its electrochemical unevenness. The anode reaction is the dissolution......
. The results show that corrosion of magnesium alloy in the bath with nickel sulfate is suffered more seriously than that in the bath with basic nickel carbonate. At low temperature, MgF2 film on the surface of magnesium alloy in the bath with nickel sulfate is not compact and the coupons of magnesium alloy have a big corrosion rate, but at high temperature, the reactive of Mg2+ and F- increases......

materials (with or without mineral admixture) plus 30% mass of limestone filler. After 28 days of curing in water at room temperature, the mortars were submerged in 2% magnesium sulfate solution... significantly improved resistances to sulfate attack. After 1 year of exposure to magnesium sulfate solutions, the formation of thaumasite was checked in the OPC mortars at both 5℃and 20......
