  • Patent number: 8012333
    Abstract: There is disclosed a process for producing an aluminium alloy sheet, which comprises subjecting a surface of the sheet to anodising conditions to form on the surface an aluminium oxide barrier layer of thickness 10 to 50 nm and treating the oxide layer with an aqueous solution of alkali to remove the layer, thereby leaving a roughened surface on the alloy sheet.
    Type: Grant
    Filed: July 19, 2002
    Date of Patent: September 6, 2011
    Assignee: Novelis Inc.
    Inventors: John Andrew Ward, Jonathan Ball, Martin Philip Amor

  • Patent number: 6524768
    Abstract: Aluminium sheet suitable for use as a lithographic plate support has a surface that is uniformly rough by virtue of: a rippled topography having an aspect ratio of at least 1.3 on a sale of 5-200 &mgr;m; and a superimposed pitted structure on a scale of 1-20 &mgr;m. A method of making the aluminium sheet involves pack rolling two aluminium ribbons to generate facing surfaces having the transverse rippled structure; followed by a small amount of a conventional roughening or graining treatment to develop the pitted structure.

  • Patent number: 6267870
    Abstract: Surface defects on rolled alulminium alloy sheet, particularly that intended for use as lithographic plate substrate, are caused by copper-containing particles. The invention provides a method of improving the sheet by removing the particles by anodising in an aggressive electrolyte, particularly a.c. anodising at a current density of at least 2 kAm−2.

  • Patent number: 5998044
    Abstract: Aluminium sheet suitable for use as a lithographic plate support has a surface that is uniformly rough by virtue of a rippled topography having an aspect ratio of at least 1.3 on a ale of 5-200 .mu.m and a superimposed pitted surface on a scale of 1-20 .mu.m.

  • Patent number: 5755949
    Abstract: A plate-, foil- or web-shaped workpiece of aluminum or an alloy thereof is subjected, in an electrolyte bath, to an alternating current at a frequency of 0.1 to 25 Hz. During the AC treatment, an anodic potential is imposed on the workpiece, in the range of 0 to 5 Volts. The total charge input is 10 to 60 kC/m.sup.2. Prior to the electrochemical graining, the workpiece is mechanically grained. After the graining steps, an etching treatment as well as an anodical oxidation and, thereafter, a hydrophilization are performed.
