Enhanced corrosion resistance properties of 15Al-85Zn coating by post-treatment with sodium hexa-meta phosphate in saline solution
Source abstract
Abstract
Different amounts of sodium hexametaphosphate (SHMP: Na 6[(PO 3) 6]) has been used to fill the defects and pores of arc thermal sprayed 15Al-85Zn coating. 73.39% porosity is reduced by 0.1 M SHMP post-treated coating due to formation of hydrogen zinc phosphate hydrate (HZP: HZn 4(PO 4) 3H 2 O). The corrosion resistance of post-treated coating is increased in 3.5 wt% NaCl solution with immersion periods attributed to the transformation of HZP into zinc phosphate (Zn 3(PO 4) 2) as well as active Zn react with Cl - and form simonkolleite (Zn 5(OH) 8Cl 2·H 2 O). Simonkolleite and zinc phosphate are sparingly soluble, therefore, post-treated coating provides two folds’ protection by HZP and corrosion products.
