Li2CO3 Surface Pre-Treatment for Improved Corrosion Control of Mg Alloy Sheet Metal

The objective of this work was to determine the extent to which a Li2CO3 surface-pretreatment can control corrosion of ZEK100 Mg alloy sheet metal product for automotive applications. The Li2CO3 surface treatment was applied through a dip coating processing using an alkaline Li salt aqueous solution. The structure and composition of the coating was determined using XRD and electron microscopy and associated techniques. The extent of corrosion …
