Hybrid Zinc-Rich Paint Coatings: The Impact of Incorporation of Nano-Size Inhibitor and Electrical Conducting Particles

摘要: Abstract In this chapter, corrosion protection performance of hybrid zinc-rich paints (ZRPs) formulated with zinc at 70 and 80 wt.%, nano-size particulates 3.21 1.75 wt.% contents is analyzed. The filler phase was composed polypyrrole supported either alumina or alumina/multiwalled carbon nanotubes. Durability the coatings tested immersion salt-spray chamber propagations. Protection mechanism ZRPs discussed regarding structural electrical properties particles paint dispersions. Hybrid indicate firm barrier nature, moderate inhibition, restrained active galvanic function to steel substrates. Hindered mass transport limited water uptake through low porosity combined three-dimensional arrangement statistical kinetic percolation thresholds are key factors provide well-balanced highly efficient combined, complex Nevertheless, incorporation inhibitor results in completely different fundamental from those typical traditional ZRPs.
