  • Tungsten disulfide surface treatment
    Patent number: 7232614
    Abstract: A tungsten disulfide metal surface treatment in which the substrate material is prepared through impingement of small blast media particle sizes to create formed pockets in the substrate material approximately matched to the size of the tungsten disulfide particles. A sand blast apparatus having a vibratory bowl with a throttled intake pipe enables small blast media particles to be used to prepare the substrate surface with the formed pockets. A method for forming the tungsten disulfide surface treatment through roughening the substrate surface in a controlled manner is disclosed.

  • Cutting tool body having tungsten disulfide coating and method for accomplishing same
    Publication number: 20040187979
    Abstract: A method of manufacturing a tool body of a cutting tool comprises mechanically shaping the tool body to provide a metal surface on the tool body having a first surface characteristic. Thereafter, the metal surface is chemically treated with a metal reactant to create a relatively soft metal film along the metal surface. This soft metal film is removed via burnishing or other appropriate action to smooth the metal surface. After the surface is smoothed, the metal surface is then roughened to prepare the surface for the receipt of tungsten disulfide. The roughened metal surface is coated with tungsten disulfide. A cutting tool is disclosed that comprises a tool body defining a substantially isotropic surface having pits formed therein, and tungsten disulfide particles filled into the pits.
