Definitions
- the invention relates to a method and means for passivating iron and steel surfaces chemically with the aid of aqueous solutions which react weakly alkaline and contain a combination of certain corrosion-inhibiting substances.
- Passivation agents are also used as an additive to forcing baths, quenching water, such as for induction hardening, cooling circuits, such as in engine test benches, and also as hydraulic fluids.
- passivation A number of methods are known for passivation. For example, it can be carried out with oils or fats or also corresponding plastic emulsions, although undesirable layers often form. Therefore, it is often advisable to passivate the metal surfaces with aqueous solutions containing appropriate chemical additives. Such corrosion inhibiting passivation Examples of iron surfaces are alkali nitrites, alkali chromates, soaps, benzoates and alkanolamines. Maleic acid monois ⁇ alkylamides have also been used for the passivation of iron and steel surfaces.
- the new method is characterized in that the metal surfaces are treated with 0.5 to 5 weight-based solutions, the pH value of which is between 7.5 and 10.5 and which is a combination which is clearly soluble in water
- the weight ratio maleic monoalkylamide to alkanolamine 1: 0.3 to 1:10 and the weight ratio maleic monoalkylamide to phosphonic acid is 1: 0.01 to 1: 0.5.
- Suitable maleic acid monoalkylamides are both amides with straight-chain and branched alkyl radicals with 6 to 14 carbon atoms, preferably with 8 to 10 carbon atoms.
- Suitable alkanolamines are short-chain compounds such as mono-, di- and triisopropanolamine, n-propanolamine, N, N, N ', N' -tetrakis (2-hydroxyethyl) ethylenediamine and preferably mono-, di- and triethanolamine especially as a mixture.
- Suitable complexing phosphonic acids are: 1-hydroxyalkyl-1,1-diphosphonic acids, 1-amino alkyl-1,1-diphosphonic acid, phosphonocarboxylic acids, such as in particular 2-phosphono-1,2,4-tricarboxylic acid and / or phosphonic acids the general formula
- 1-hydroxyethane-1,1-diphosphonic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid and nitrilotrimethyleneph ⁇ sphonic acid have proven successful.
- the phosphonic acids can also be used as alkali salts or alkanolamine salts. Free phosphonic acids can also be added to the corresponding solutions. In such a case, then by an excess of alkanolamine in the solution these are adjusted to pH 7.5 to 10.5.
- An essential feature of the combination according to the invention is the weight ratio of maleic acid monoalkylamide to alkanolamine, which is 1: 0.3 to
- the weight ratio of maleic acid monoalkylamide to phosphonic acid in the process according to the invention is 1: 0.01bi ⁇ 1: 0.5 and preferably 1: 0.1 to 1: 0.5.
- a further increase in the phosphonic acid addition is possible, but does not bring any additional synergistic effects.
- the pH of the solution from 7.5 to 10.5 that is suitable for carrying out the process is not already achieved by the alkalinity of the substances used, it can be adjusted by adding a small amount of alkali.
- the metal surfaces made of iron or steel can be treated at elevated temperatures between 30 and 10 ° C., but preferably at room temperature.
- the agents can also contain further substances.
- surfactants preferably nonionic low-foaming surfactants.
- the following are low-foaming nonionic surfactants: the adducts of ethylene or propylene oxide with polypropylene glycol or polyethylene glycol and adducts of ethylene and / or propylene oxide with mono- or polyalcohols, mono- or polyamines, fatty acids, amides and alkylphenols with an alkyl radical of preferably 8 to 20, especially 12 to 18 carbon atoms.
- the concentration in the aqueous passivation solution is between 0.005 to 0.3 percent by weight.
- the agents according to the invention can also contain alkanolamine soaps of short-chain fatty acids - i.e. of fatty acids with 6 to 12 carbon atoms -, for example caprylic or isononanoic acid, which reinforce the corrosion protection effect in a manner known per se and act as a solubilizer and as a foam regulator.
- the solutions according to the invention can optionally also contain preservatives for preventing bacterial decomposition, such as, for example, chlorophenols, diphenyl derivatives, hexahydrotriazine derivatives and / or for non-ferrous metal inhibition, benztriazole, mercaptobenztriazole and lignin sulfonate in amounts of about 0.05 to 0.1 percent by weight.
- preservatives for preventing bacterial decomposition such as, for example, chlorophenols, diphenyl derivatives, hexahydrotriazine derivatives and / or for non-ferrous metal inhibition, benztriazole, mercaptobenztriazole and lignin sulfonate in amounts of about 0.05 to 0.1 percent by weight.
- the agents used contain the components mentioned in the stated amounts. Ge if desired, however, the corresponding agents can also be prepared in concentrated form in order to be diluted to the stated concentration immediately before use.
- the corrosion protection obtained with the solutions according to the invention is considerably higher than the sum of the properties of the individual substances and exceeds the passivating agents used to date.
- the outstanding corrosion-protecting properties of the process according to the invention were tested in the corrosion protection test according to DIN 51 360/2 with casting chips GG 30 at exposure times of 2 hours.
- the test solutions were prepared at room temperature with 20 hard water.
- the pH of all test solutions was between 8, 5 and 10.5; Test and comparison solution were adjusted to the same pH.
- the concentration of the respective combination was 1, 1.5 and 2% in the DIN tests.
- the comparative tests are listed in the table under a), and the solutions according to the invention are listed under b).
- non-ionic surfactant (adduct of ethylene oxide with polyethylene glycol)
