Definitions

  • This invention relates to a method for obtaining images ongenerally metal surfaces, and particularly on steel articles or panels by a panel glazing operation and an oxidation colouring process.
  • the invention also relates to the metal articles or panels having the images as provided by the claimed method.
  • This invention is proposed for providing novel decorative means to obtain on generally metal surfaces, and particularly steel panels, any images by taking advantage of the chemical and/or physicalproperties of the metals, allowing also the exploitation of the invention on an industrial scale, in addition to solving aesthetical problems by novel means.
  • the metal surface in the case subjected to oxidation precolouring by heat treatment when steel or iron material panels are concerned with, is given the reproduction by a silk-screen printing process for the desired image or images using a per se known protective ink capable of withstanding a mechanical abrasive actionfand-"acid resistant; the metal surface is mechanically and/or chemically processed so that its surface aspect will be altered, then removing the protective ink to cause the desired image or images to appear by contrast between the processed and unprocessed surfaces.
  • FIGS. 1 to show the sequence as followed for the several steps in the method for obtaining an image on a steel plate which has been coloured by oxidation through a heat treatment and then subjected to a mechanical glazing process to provide the panel with the desired aesthetical effect.
  • FIGS. 1 to show the sequence as followed for the several steps in the method for obtaining an image on a steel plate which has been coloured by oxidation through a heat treatment and then subjected to a mechanical glazing process to provide the panel with the desired aesthetical effect.
  • a general steel panel is shown therein, designated as a whole at 10 and obtained, for example, from a fiat steel plate or from roll steel cut and in the case preshaped to the desired flat or box-like form.
  • panel 10 has a quite smooth surface, as shown in the top half of FIG. 1, free of any oxidation or scratch trace.
  • the panel surface can be suitably protected by a selfadhering plastic sheet (not shown) to retain the panel surface at a completely unaltered condition.
  • this steel panel is subjected to a heat colouring process, so that the steel plates will oxidize with varying colourings, the strength of which being proportional both to the temperature attained. by the panel and the nature of the panel.
  • the method for colouring the steel panel by oxidation consists of evenly or unevenly heating the panel in induction furnaces or the like, or manually by torches, to that temperature to which a desired tempering colour will correspond and then allowing it to cool.
  • the colour corresponding to the attained temperature will indelibly remain on the surface, as schematically shown on the bottom half of FIG. 1.
  • the finishing of the metal panel surface may be whatever, such as semiglossy, opaque, bright, mirror-like as well as the nature of metals, particularly steel, may be whatever depending on the environment the panel is to be exposed to; for example, in particularly corrosive environments, such as in proximity to the sea and contaminating sources, it is possible and convenient to use special stainless steels, such as AISI 316 and A181 304 steels.
  • a white steel surface will be now provided, this surface having one or more image zones, one of which is shown in FIG. 3 at 11, covered and protected with said special silk-screening ink.
  • the following processing on the steel panel is optional, and is carried out by following the subtractive method, or better to say by material removal through a smooth abrasion throughout the entire unprotected plate surface.
  • This smooth abrasion or glazing is effected according to a preset direction and is carried out by using a glazing machine carrying special silicon carbide or aluminium oxide rollers which, by variable speed and such a glazing will modify the original finishing of the panel surface, at the portion obviously exposed from the protective ink (FIG.
  • said special rollers are commercially known as Scotch-Brite and are available and marketed by 3M-Minnesota, substantially comprising rollers having a partially resilient cellular structure, incorporating abrasive granules so that the abrasion action on the metal panel surface will not be deep and suitably endured by the protective ink layer at the image zones.
  • the protective ink is removed from the image zones by using a suitable cloth soaked in trichloroethylene or acetone to complete cleaning and clear appearance of the image or images, which will appear clear and rich in tones on a glazed surface background, as shown in FIG. 5.
  • the method just described could be carried out according to other many changes; for example, a plurality of silk-screening or countersilk-screening operations could be effected in different directions on the oxidized panel, or otherwise the oxidation could even be omitted and silk-screening be used alone to fix and form the image on the panel.
  • a plurality of silk-screening or countersilk-screening operations could be effected in different directions on the oxidized panel, or otherwise the oxidation could even be omitted and silk-screening be used alone to fix and form the image on the panel.
  • the panel may be of any metal.
  • the images so obtained have a very wide range of effects, it being possible to use the reflection, brightness or opacity of the metal surface separately of in combination with the numberless changes in oxidation colour making an extremely wide application field for the invention.
  • a method of applying a predetermined pattern of complex contrasting areas to a metal surface comprising the steps of 1 heating the metal surface to impart a nonuniform coloring thereto,
  • heating step comprises imparting a colored finish to the metal surface by heating at least a portion thereof to a preselected temperature.
  • treating step comprises removing the colored finish from the unprotected surface areas by exposing the same to an inorganic mineral acid solution.
