Novel Insights into Lead Corrosion Control: Safely Changing Source Waters, Effective Use of Zinc Phosphate Inhibitors, Electrochemical Reversal of Solder, and Significance of Lead-Polyphosphate Complexation
… 2) demonstrate that in certain corrosive waters zinc orthophosphate can dramatically reduce lead contamination from solder at pHs around 7.5-9.5, but is ineffective in relatively non-corrosive waters or at pHs outside this range, 3) reveal that prolonged exposure to free chlorine can dramatically …

Phosphate stabilization by non-chromate post-rinse treatment
Zinc phosphate conversion coating has been applied to improve the corrosion resistance and paint adhesion. However, zinc phosphate crystals dissolve in a highly alkaline environment, which reduces the corrosion resistance of base metal. To improve the phosphate stability in a highly alkaline …

Development of Anti-corrosive Polyester Powder Coatings
… types of additives and functional filler, namely zinc phosphate with passivation effect, zinc powder with sacrificial anode effect, and two nanoclays with barrier effect were incorporated into the coatings to enhance the anti-corrosive performance. The anti-corrosive properties were evaluated by …

EXPERIMENTAL STUDIES OF THE CHEMICAL EFFECTS OF ZINC-BEARING MATERIALS FOLLOWING A LOSS-OF-COOLANT ACCIDENT IN A PRESSURIZED WATER REACTOR
… the potential debris loading contributions of zinc-bearing materials found in the containment building. Zinc-bearing materials in containment include galvanized steel and inorganic zinc-coated steel (IOZ). This research has shown that zinc interacts with post-LOCA containment chemistry to form …

Surface properties and the bioactivity of glass-ionomer dental cements and related materials
… indicated that a surface layer of calcium phosphate had formed and created a barrier around the cement preventing the loss of strengthening ions. An investigation was also made into formulating a novel hybrid cement. This process included the deployment of additives/co-reactants within the …

Perovskite interfaces with protective zinc compounds – DFT computation and related experiments
… nanocrystals and protective shells made of zinc compounds such as zinc sulfide and zinc phosphate. The results indicate that pure ZnS is unlikely to form stable bonds with the Pb-I terminated perovskite (100) surface at any orientation or termination. Therefore, the existence of the …

Phase selective flame-retardant laminates
… synergistic FR systems – Boehmite/Melamine poly(zinc phosphate) (AlOOH/MPZnP), Aluminium diethylphosphinate/Melamine cyanurate (AlPi/MC), and Expandable graphite/Melamine polyphosphate) (EG/MPP) – were selected to enhance fire performance. Concentrating FRs in the top layer offers fire protection …

Effect of zinc substitution on the structure of calcium Fluoro-Alumino-Silicate glasses and glass-ceramics
… and the glass ceramic. This work focuses on zinc substitution for calcium. Zinc compared to calcium is a smaller cation with an atomic radius of 1.34 Å against 1.97 Å for calcium. Zinc has been proven to be bactericidal and has shown ability to stimulate osteogenesis. A series of zinc …

An interdisciplinary study of cathodic debonding in elastomer/metal adhesive bonds
… when an imposed current was used. The use of zinc phosphate-coated steel substrates is shown to improve bond durability significantly at low voltages. Similar trends are observed when silane (γ-aminopropyltrimethoxy) modified primer were used in bonding. Two approaches are used in order to …
