Definitions
- the present invention relates to a thermally sprayed corrosion layer for reinforced concrete based on zinc and methods for producing the same.
- Thermally sprayed layers of zinc have long been used as anodes to protect reinforced concrete structures.
- the thermally sprayed zinc anode which is applied to the outer surfaces of the structures using thermal spraying processes, takes on the function of protecting the steel reinforcement against corrosion.
- This anode can be used both as a galvanic sacrificial anode or as an anode in corrosion protection systems operated with external current.
- the service life of such zinc anodes is significantly influenced by the external corrosion and the erosion of the spray coating.
- EP 0 305 914 A2 describes a method for treating rolled steel to increase the corrosion resistance, a coating of zinc powder preferably being applied.
- This rolled steel is used in particular in reinforcing steel or prestressing steel.
- the rolled steel is coated with the metallic powder directly from the rolling heat at temperatures below 600 ° C.
- a coating of a synthetic resin, such as epoxy resin is applied.
- EP 0 668 364 AI describes aluminum-zinc alloys for the cathodic protection of reinforced concrete with zinc contents of 10% to 50%.
- a disadvantage of these aluminum-zinc alloys is their low resistance to higher pH values of the concrete between 11 and 14.
- severe under-corrosion of the coating sets in which can lead to the coating flaking off. Pure zinc layers do not show this behavior and are therefore more suitable for direct contact with the concrete surface.
- JP 0831159 A describes an aluminum alloy for corrosion protection of reinforced concrete with a zinc content of 2-7%.
- JP 08199279 A describes an alloy for the corrosion protection of reinforced concrete with a zinc content of 7-50%.
- EP 0 591 775 AI describes a method in which a rough epoxy-polyamide primer layer is first applied to the concrete surface. An aluminum alloy or a zinc-aluminum pseudo-alloy is then sprayed onto this primer layer, which is operated with external current.
- JP 6-2174 A describes a method in which a rough primer layer is also applied to the concrete surface. Then aluminum or an aluminum alloy is sprayed on. In addition, zinc, a zinc alloy or zinc pseudo alloy is applied to this layer.
- the primer layer is necessary in both processes because direct contact of aluminum or aluminum-zinc alloys with the concrete surface is to be avoided. It is thus known that the corrosion resistance of thermally sprayed zinc layers can be improved by alloying the zinc wire with aluminum, the aluminum content being between 2 and 33, preferably between 15 and 22%. This applies in particular when zinc layers are to be exposed to a chloride-containing or moist atmosphere, cf. DE 198 11 447 A1.
- These zinc / aluminum alloys can be applied thermally to reinforced concrete surfaces in the same way as layers of pure zinc. Due to the high pH value of the concrete between 11 and 14, the above-mentioned under-corrosion, in particular of the aluminum-rich zones, occurs with such layers of zinc / aluminum alloys. The resulting corrosion products tend to expand and form bubbles.
- the object of the invention is to utilize the better corrosion resistance of zinc / aluminum alloys on the one hand, and to avoid the disadvantages of undercorrosion observed on the other hand.
- the layer consists of at least two layers, of which the first layer sprayed directly onto the concrete consists of pure zinc and the second layer subsequently sprayed onto it consists of a zinc / aluminum alloy.
- This second layer contains 4 to 33% by weight, preferably 15 to 22% by weight, of aluminum.
- the properties can also be improved if 0.002 to 0.04% by weight indium is added to this zinc / aluminum alloy.
- Optimal results are achieved if a third layer based on polyurethane, which is able to at least close the pores of the second layer, is applied to the second layer.
- the first layer sprayed directly onto the concrete generally has a layer thickness of 100 to 400 ⁇ m.
- Wire suitable for applying the second layer is described, for example, in German patent application 198 11 447.8.
- a particularly suitable one-component, moisture-curing polyurethane resin and its use are described, for example, in EP-A-0 677 592.
