Definitions
- Electrolytically galvanized steel sheet which is manufactured on continuously working finishing plants, is increasingly used for the manufacture of household and electrical appliances and in the automotive industry.
- the steel sheet pre-finished on two sides or only on one side is given an active corrosion protection by the zinc coating and, together with a corresponding chemical pretreatment, offers an excellent base for subsequent painting or coating.
- electrolytically galvanized steel sheets with increased zinc coating are often used.
- thinner coatings can be deposited during electrolytic deposition and tighter layer thickness tolerances can be maintained.
- the electrolytically deposited coatings are even and fine-grained; the mechanical-technological characteristics of the steel carrier material are not changed during electrolysis.
- the possibility of one-sided electrolytic refinement is simple from the principle of the process; the raw side of such electrolytically galvanized steel sheet meets the requirements such. B. the automotive industry.
- a reduced layer thickness not only saves coating metal and the electrical energy required for deposition, but also increases the throughput speed in existing finishing plants.
- the method according to DE-OS 30 31 501 is characterized by a coating of a zinc-nickel alloy with a nickel content of 10 to 15% by weight, which is applied directly to steel or to a thin nickel primer, i.e. H. as a two-layer structure.
- the further known method according to DE-OS 30 05 159 is also characterized by a zinc-nickel deposition which is carried out under different process conditions.
- the method according to DE-OS 30 24 932 is characterized by a single-layer coating of a zinc-iron alloy with an iron content of 5 to 35% by weight or by a coating of a zinc-iron alloy with additions of nickel and / or chromium and / or copper, the content of the alloy metals nickel, chromium and / or copper being 0.01 to 10% by weight of the coating.
- the process according to DE-OS 29 46 668 is characterized by a coating of a zinc-iron alloy with an iron content of 1 to 60% by weight, in a two-layer structure on a coating of pure zinc or a zinc alloy with low cobalt and Chromium and / or indium and / or zirconium.
- the disadvantages which have been experienced in the processes which have become known to date, such as significant crack formation during forming, reduced so-called bare corrosion resistance and greatly reduced cathodic protective action, are to be avoided.
- the suitability of the material for resistance welding and phosphating should be preserved.
- the steel sheet with a continuous electrolytic deposition on one or two sides a coating of a zinc alloy is provided, which contains 1 to 20 wt .-% nickel and 0.1 to 5 wt .-% iron.
- the nickel content should preferably be kept below 10% by weight, the iron content preferably 3 to 5% by weight.
- This coating of the zinc alloy mentioned can be applied to the steel sheet either in one layer or in a two-layer process on or under an electrodeposited coating of pure zinc or another zinc alloy.
- the total thickness of the coating is in the monolayer or two-layer structure from 0.5 to 15 / um on each side, wherein the thickness of the coating of the said zinc alloy in a two-layer structure of at least 0.1, to lie to each side.
- the zinc alloy is preferably deposited from a sulfate-acidic electrolyte, preferably soluble anodes being used.
- the surface of a cold-rolled steel strip is first degreased electrolytically in an alkaline solution, rinsed and then electrolytically coated with a zinc alloy coating in the single-layer structure, rinsed and dried.
- the alloy coating according to the invention with a coating thickness of 5 ⁇ m after phosphating and chromate passivation is twice as corrosion-resistant as a zinc coating of the same thickness and aftertreatment.
- a test sample with an alloy coating after phosphating, cathodic electrodeposition coating and simulated stone impact loading behaves three times better than a test sheet with zinc coating.
