Abstract: The invention relates to the use of ceramic, plasma-deposited, layers for manufacturing plastic articles whose function requires low-friction surface. The invention further provides a process of manufacturing a polymer object having a low-friction surface, comprising i) providing a mold defining the shape of said object; ii) coating said mold that defines the shape of said low-friction surface with a ceramic layer, the layer being formed by plasma deposition; and iii) molding the polymer in said mold. The invention also provides a polymer article having a low-friction surface created by molding on a plasma-deposited ceramic surface.
