ADHESION OF METALLIZED ZINC COATINGS ON CONCRETE: "PART 2"

Corrosion of the steel reinforcement in bridges is being increasingly mitigated by the technique called cathodic protection. One cathodic protection system which has recently gained a lot of attention uses thermally sprayed zinc as the anode. The present paper discusses factors which have been found to affect the adhesion of metallized zinc on concrete. The cohesive strength of the concrete, its moisture content and surface temperature during the metallizing, and the way it was grit blasted all affect the adhesion of arc sprayed zinc on concrete. Minimizing the spray thickness per pass also improves the adhesion of the arc sprayed zinc coating.
