Den foreliggende opfindelse angår en fremgangsmåde til fremstilling af mørkegrå til sorte dæklag med ensartet farvetone pa formlegemer bestående af zink-kobber-titan-legeringer, især plader og bånd fremstillet til valsning.BACKGROUND OF THE INVENTION The present invention relates to a process for producing dark gray to black cover layers of uniform tint on moldings consisting of zinc-copper-titanium alloys, in particular sheets and strips made for rolling.
5 Under normale atmosfæriske betingelser danner der sig på overfladerne af formlegemer bestående af zink eller zinklegeringer beskyttende dæklag af basisk zinkcarbonat. Dannelsen af disse dæklag varer oa. tre dage i en atmosfære med en relativ luftfugtighed på 75%. Disse dæklag har af-10 hængigt af den legeringsmæssige sammensætning, den stedlige beliggenhed samt atmosfæren og tiden en lysegrå til mørkegrå farvetone. Dannelsen af sådanne dæklag hæmmes eller forhindres imidlertid af indholdet af forureninger i luften, f.eks. af svovldioxid.5 Under normal atmospheric conditions, protective surfaces of basic zinc carbonate zinc or zinc alloys form on the surfaces of mold bodies. The formation of these cover layers lasts, among others. three days in an atmosphere with a relative humidity of 75%. These coatings depend on the alloy composition, the location and the atmosphere and the time a light gray to dark gray hue. However, the formation of such cover layers is inhibited or prevented by the content of air pollutants, e.g. of sulfur dioxide.
15 Af æstetiske grunde er det derfor i mange tilfælde nødvendigt med en overfladebehandling. De tekniske fordele ved en sådan behandling består i , at dæklagsdannelsen gøres ensartet. Ved overfladebehandling kan der opnås en ensartet farvevirkning, der af æstetiske grunde ofte er sær-20 deles ønskelig.15 For aesthetic reasons, therefore, in many cases a surface treatment is necessary. The technical advantages of such a treatment consist in the uniformity of the tire layer formation. In surface treatment, a uniform color effect can be obtained, which is often very desirable for aesthetic reasons.
Som fremgangsmåde til kemisk passivering af overflader bestående af zink eller zinklegeringer anvendes der foruden den galvaniske overfladebehandling i relativt stort omfang chromatering og phosphatering. Ved chromatering 25 behandles de rensede og forbehandlede overflader med fortyndet chromsyre eller chromatopløsninger. Til disse opløsninger sættes der bestemte mængder uorganiske syrer eller salte til opnåelse af bestemte farvetoner og lagtykkelser. De således behandlede overflader udviser farve-30 toner fra svagt gul til olivenbrun. Dæklagene bestående af chromhydroxyd og basisk chrom-(III)-chromat har en tykkelse på <1 pm til ca. 5 pm.As a method of chemical passivation of surfaces consisting of zinc or zinc alloys, in addition to the galvanic surface treatment, chromating and phosphating are used to a relatively large extent. In chromation 25, the cleaned and pretreated surfaces are treated with dilute chromic acid or chromate solutions. To these solutions, certain amounts of inorganic acids or salts are added to obtain certain color tones and layer thicknesses. The surfaces thus treated exhibit color tones from pale yellow to olive brown. The layers of chromium hydroxide and basic chromium (III) chromate have a thickness of <1 µm to approx. 5 pm.
Phosphateringen kan efter tilsvarende forbehandling gennemføres ved en phosphorsyrebejdse- eller -lagdannende 35 phosphateringsmetode. Phosphatovertrækkenes lagtykkelse varierer sædvanligvis mellem 2 og 15 pm. De førnævnteAfter similar pretreatment, the phosphating can be carried out by a phosphoric acid working or layer forming phosphating method. The layer thickness of the phosphate coatings usually varies between 2 and 15 µm. The aforementioned

fremgangsmåder er, betinget af de forholdsvis talrige fremgangsmådetrin, forbundet med betydelige omkostninger.methods are, subject to the relatively numerous process steps, associated with significant costs.
En yderligere ulempe består deri, at de chromaterede eller phosphaterede halvfabrikata ikke kan loddes uden en tilsva-5 rende forbehandling, således at f.eks. forarbejdningen af zinkplader inden for byggeindustrien er betydeligt vanskeliggjort.A further disadvantage is that the chromated or phosphated semi-finished products cannot be soldered without a corresponding pretreatment, so that e.g. The processing of zinc sheets in the construction industry is considerably difficult.
Ifølge den foreliggende opfindelse er der tilvejebragt en fremgangsmåde af den i indledningen nævnte art, 10 hvilken fremgangsmåde er ejendommelig ved, at formlegemerne behandles i en opløsning bestående af 60-90 volumenprocent vand, 10-40 volumenprocent salpetersyre og 5-10 volumenprocent svovlsyre.According to the present invention there is provided a process of the kind mentioned in the preamble, characterized by treating the molding bodies in a solution consisting of 60-90% by volume water, 10-40% by volume nitric acid and 5-10% by volume sulfuric acid.
Afhængigt af den ønskede farvetoning er formlegemernes 15 gennemløbshastighed gennem behandlingsbadet 0,5-50 m/min., fortrinsvis 0,5-30 m/min.Depending on the color tint desired, the flow rate of the molding bodies 15 through the treatment bath is 0.5-50 m / min, preferably 0.5-30 m / min.
Hvis de formlegemer, der skal behandles, endnu udviser urenheder, er det nødvendigt at affedte dem før bejdsningen og eventuelt skylle og børste dem.If the moldings to be treated still exhibit impurities, it is necessary to degrease them before pickling and possibly rinse and brush them.
20 Ved den praktiske gennemførelse af fremgangsmåden ifølge opfindelsen trækkes f.eks. et valset bånd af en zink-kobber-titan-legering med sammensætningen 0,14 vægt-% kobber, 0,13 vægt-% titan, 0,01 vægt-% aluminium og resten finzink, med en tykkelse på 0,72 mm med en hastighed på 8 m/min. gen-25 nem et behandlingsbad bestående af 85 volumenprocent vand, 10 volumenprocent salpetersyre og 5 volumenprocent svovlsyre, hvorefter det skylles, børstes og tørres. Efter denne behandling er båndets overflade farvet mørkegrå til sort.In the practical implementation of the method according to the invention, e.g. a rolled strip of a zinc-copper-titanium alloy of the composition 0.14 wt% copper, 0.13 wt% titanium, 0.01 wt% aluminum and the balance fine zinc, having a thickness of 0.72 mm with a speed of 8 m / min. through a treatment bath consisting of 85% by volume water, 10% by volume nitric acid and 5% by volume sulfuric acid, after which it is rinsed, brushed and dried. After this treatment, the surface of the ribbon is colored dark gray to black.
De ved den foreliggende opfindelse opnåede fordele 30 består deri, at det med relativt enkle midler lykkes at overfladebehandle formlegemer bestående af zink eller zinklegeringer, uden at man behøver at vente på den ved langtidsindvirkning af atmosfæriske påvirkninger forårsagede lysegrå til mørkegrå farvning af overfladen. Denne fordel imø-35 dekommer især den af æstetiske grunde forårsagede stræben efter en ensartet farvning, f.eks. af plader, der anvendes indenThe advantages of the present invention consist in the fact that, with relatively simple means, they succeed in coating surface bodies of zinc or zinc alloys, without having to wait for the light gray to dark gray staining of the surface caused by long-term effects of atmospheric influences. This advantage in particular accommodates the pursuit of uniform coloration caused by aesthetic reasons, e.g. of sheets used within
