Protectivity and Adhesive Strength of Zinclipscombite Coating on 316L Stainless Steel
Zinclipscombite (ZnFe3+2(PO4)2(OH)2) coating layer was prepared on 316L SS. The 316L SS plates were treated using hydrothermal treatment at 200°C for 2, 6 and 24 h. The ZnFe3+2(PO4)2(OH)2 layer strongly attached to the 316L SS surface. The adhesive strength of the coating layer was measured higher than 65.7 ± 3 MPa. The surface observation and element analysis indicated that the 316L SS plates were covered with ZnFe3+2(PO4)2(OH)2 coating layer after hydrothermal treatment. Linear voltammograms for treated sample at 200°C for 24 h showed higher corrosion resistance. The ICP results proved protective property for the zinclipscombite coating agains PBS solution.
