  • Method for the manufacture of an article and an article
    Patent number: 6767617
    Abstract: A method for the manufacture of an article having first and second surface regions of different coefficients of friction in a treatment chamber with a rotary support for the articles and capable of simultaneously carrying out at least two PVD coating processes. The first PVD coating process is carried out with a comparatively directed vapor flux from one or more targets which can compose one or more of the elements B, Si, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta and W, carbides of these elements and carbon. A second PVD coating process is carried out with a comparatively less directed or non-directed vapor flux of carbon.
    Type: Grant
    Filed: February 7, 2001
    Date of Patent: July 27, 2004
    Assignee: Hauzer Techno Coating Europe BV
    Inventors: Gerrit Jan van der Kolk, Antonius P.A. Hurkmans, Christian G.C. Strondl
  • Method for the manufacture of coatings and an article
    Patent number: 6599400
    Abstract: The invention relates to a method for the manufacture of coatings having a low coefficient of friction on articles such as mechanical components and tools, with a layer sequence of carbon and a carbide of at least one element in the form of a metal and/or silicon and/or boron being deposited on the article by means of a PVD process. Articles which have such a layer sequence are also claimed. The coating has a low coefficient of friction, is wear-resistant and has a relatively high hardness and also relatively high elasticity.
