Increasing corrosion-resistance of thermally sprayed metal coating on steel-reinforced cement concrete

摘要

The invention relates to a method for improving the corrosion resistance of reinforced concrete coated with a thermal spray coating made of metal, especially zinc or zinc alloys. The spray coating is electrically interconnected to the reinforcement and additionally coated with a polyurethane resin which is applied as a low viscosity solution in the organic solvents.
