A rotary drive which is suitable in treatment of three-dimensional workpieces. In this rotary apparatus, only the removably mounted rotatable rods that serve as sample holders are connected to high voltage, which is delivered via a central high-voltage lead-in at the lower end of the rods, while the actual drive elements for rotating the rods are electrically insulated therefrom by suitable ceramic insulating elements.

Rotating device for plasma immersion supported treatment of substrates

A combination wear protection film for components made of substrates susceptible to wear is described. The film has a wear-resistant surface film that contains one or more of the elements carbon, nitrogen, or boron, the proportion of this element&mdash;or, if more than one of these elements is present, the sum of the proportions of the elements present&mdash;is at least 30% by atomic weight, preferably at least 40% by atomic weight; and a support film, located between a substrate and the surface film and made of a plasma polymer, that exhibits a quasi-continuous transition in modulus of elasticity and optionally in hardness from a value of a base film to a value of the surface film. A method for producing a wear protection film of this kind, and objects equipped with the wear protection film is also described.

Combination antiabrasion layer

In the process for coating the elastomeric rubber wiper a vaporous coating material is generated and activated by a plasma and/or laser; a protective coating is formed on a rubber wiper surface by exposing it to the vaporous coating material by CVD and/or PVD methods and process parameters for the coating process are controlled so that the protective coating includes at least three coating layers and has a total thickness of from 200 nm to 2 &mgr;m. The coating layers include at least one thicker softer elastic coating layer with elastomeric properties similar to those of the rubber wiper and other thinner harder coating layers having wear-resistant properties. The other thinner harder coating layers have respective hardness increasing from an inner most one to an outermost one of the other thinner harder coating layers.
