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.
