AN IMPROVEMENT TO THE ANTICORROSIVE PROPERTIES OF EPOXY POWDER COATING BY ZINC PHOSPHATE AND ZINC ALUMINUM PHOSPHATE PIGMENTS
Epoxy powder coatings containing zinc aluminum phosphate (ZAP) and zinc phosphate (ZP), which are the 2nd and 1st generation of phosphate-based pigments respectively, were applied to the surface of mild steel sheets. The anticorrosive performances of the coated samples were studied using electrochemical impedance spectroscopy (EIS). Cathodic disbonding resistance and the adhesion performance of...
متن کاملEffect of Zinc Phosphate on the Corrosion Behavior of Waterborne Acrylic Coating/Metal Interface
Waterborne coating has recently been paid much attention. However, it cannot be used widely due to its performance limitations. Under the specified conditions of the selected resin, selecting the function pigment is key to improving the anticorrosive properties of the coating. Zinc phosphate is an environmentally protective and efficient anticorrosion pigment. In this work, zinc phosphate was u...

متن کاملHydroxyapatite coating on - - zlrconlausing glass coating technique
The aim of this study was to deyelop a noyel hydroxyapatite (HA) coating method on zirconia using glass coating technique. A borosi)icate glass, the mixture of the glass ttnd HA (3e, 50, 70, and 90 mass%), and the 100% HA were coated on two kinds of zirconia discs and fired at 900-950'C. After the final coating, the surface of the sample was etched for 3 min in an acid-mixture of 3% HF and 5%HN...
