Definitions
- the present invention relates to wire based on Zinc and aluminum, which can be used in thermal Spraying as protection against corrosion, in particular as protection against corrosion against high air humidity and high chloride ion concentrations e.g. in marine environment, road salt etc.
- DE 30 07 850 C2 describes the use of a zinc alloy as a powder for mechanical plating, one Alloy to be used, zinc and one or more Alloy additives, such as 0.1 to 60% aluminum, up to 5% Nickel, up to 3% magnesium, up to 3% copper, up to 2% silicon, up to 1.5% titanium, up to 1% antimony, up to 1% silver, up to 0.5% Chromium, 0.5% beryllium, up to 0.1% calcium, up to 0.1% cobalt, up to 0.1% sodium, up to 0.1% potassium, 0.1% indium, up to 0.05% Lithium, 0.05 strontium, each based on the total weight of the alloy, except for the weight of the impurity mechanical plating with a metal powder will do this Powder mechanically applied to the substrate, whereby a Forms layer of 10 microns.
- Roll cladding, also under Use of aluminum powder is described for example in the aluminum paperback, 13th edition, 1974, page 927, paragraph 1 and 2.
- DD-PS 4,822 describes that it is possible to use zinc-aluminum alloys in the area of eutectoid decay due to annealing and then quenching into objects with high shape changing capacity to process.
- zinc-aluminum alloys Made of this material an alloy wire with 80 % Zinc and 20% aluminum.
- wires for thermal spraying either consist of Fine zinc, made from a pure zinc / aluminum alloy with 15% by weight Aluminum or aluminum with 5% by weight magnesium.
- the invention has therefore set itself the task of zinc wire based on zinc and aluminum, which is both in the condensed water test and in the salt spray test has good corrosion resistance according to DIN 50021 and thus if possible the corrosion resistance of aluminum with 5% magnesium also against high air humidity and high chloride ion content, i.e. the salt spray test according to DIN 50021 or is even more corrosion resistant.
- This task has now been solved using zinc-based wire and aluminum, which in addition to zinc and the usual impurities 8 to 33% by weight aluminum and up to 500 ppm indium contains.
- This wire preferably contains 10 to 24% by weight.
- Wire with a content of 15 to is very particularly preferred 22% by weight aluminum and 20 to 200 ppm indium.
- the wire according to the invention can be produced by conventional methods be, namely by casting the liquid alloy as Cast strand with subsequent rolling and drawing. For this Processes are again alloys with only 10 to 24% by weight Aluminum preferred as alloys with a higher aluminum content are more difficult to process.
- the wire according to the invention can in the usual way thermal spraying can be used, for example by Wire flame spraying or wire arc spraying. This procedure differ mainly by different process temperatures and therefore also through different order efficiencies.
- Figure 1 shows that the condensation test the worst according to DIN 50018-KFW 0.2 s pure zinc Has values, but also aluminum with 5% by weight of magnesium corroded.
- the previously common zinc wire with 15% by weight Aluminum has good values here.
- Zinc wires with 22, 33 and 55 wt .-% aluminum already have worse values.
- Zinc alloys with more than 25% by weight Aluminum is becoming increasingly difficult to process into wire.
- Example 2 The same wires as in Example 1 were subjected to the salt spray test subject to DIN 50021 - SS. The results are in the Figure 2 reproduced. It follows that again Feinzink delivers the worst results and on top of that in shows considerable red rust formation. In contrast shows that previously chosen aluminum for such conditions with 5% Magnesium significantly better values and no red rust formation.
- Zinc and aluminum wires containing 22% by weight Aluminum and increasing amounts of indium were subjected to the salt spray test exposed to DIN 50021 - ss. The results are in the Figure 3 compiled, again for comparison Fine zinc and zinc with 15% aluminum are also shown. From this it follows that already 20 ppm indium to a considerable Carry out and improve the corrosion behavior increasing amounts of indium further corrosion behavior can be improved. Amounts greater than 500 ppm are indium neither responsible for price, nor lead to one further improvement of properties. On top of that is too note that by adding large amounts of indium the Processability of the alloy to wire deteriorates.
