Title:
HARD MATERIAL LAYER
Document Type and Number:
WIPO Patent Application WO2003031685
Kind Code:
A3
Abstract:
The invention relates to a hard material layer having a relatively low frictional resistance. Such hard material layers can, for example, be produced by impregnating said layers with a lubricant. According to the present invention, a zirconium oxynitride layer, which has a zirconium-, nitrogen- and oxygen-containing phase, is used as a hard material layer. It has been surprisingly shown that the presence of said phase in the zirconium oxynitride layer leads to a perceptible reduction of the layer frictional resistance, such that further processing steps can advantageously be saved on coating of substrates, such as impregnation. The aforementioned coating (26) can, for example, be applied on a tool (27), which is appropriate for metal-cutting machining a work piece (28). With said low frictional resistance, a dry machining of said work piece (28) can be executed by means of said tool. Another application is the coating of highly stressed components of a fuel injection valve.
