Axial-piston machine having an antiwear layer

Abstract

An axial piston machine having a control plate and a cylinder drum rotating relative to the control plate. The control plate rubs or slides on a second sliding side of the cylinder drum via a first sliding side. One of the sliding sides has a carbon-containing layer.

1 - 8 . (canceled) 
   
   
       9 . An axial piston machine, comprising:
 a control plate; and   a cylinder drum which rotates relative to the control plate, the cylinder drum and the control plate rubbing or sliding against each other, the control plate rubbing or sliding on a second sliding side of the cylinder drum via a first sliding side of the cylinder drum, wherein one of the first sliding side and the second sliding side has a carbon-containing layer, and the other of the first sliding side and the second sliding side is made of metal.   
   
   
       10 . The axial piston machine as recited in  claim 9 , wherein the sliding side made of metal is made of steel hardened by nitration. 
   
   
       11 . The axial piston machine as recited in  claim 9 , wherein the layer is applied on the first sliding side. 
   
   
       12 . The axial piston machine as recited in  claim 9 , wherein at least one of the control plate and the cylinder drum is made of metal in a region of the first and second sliding sides, and the layer is applied directly on a metal surface of the one of the first or second sliding side. 
   
   
       13 . The axial piston machine as recited in  claim 9 , wherein the layer is a diamond-like amorphous carbon layer. 
   
   
       14 . The axial piston machine as recited in  claim 13 , wherein the layer is a tetrahedral, hydrogen-free amorphous carbon layer (ta-C). 
   
   
       15 . The axial piston machine as recited in  claim 9 , wherein the layer is a diamond layer, the diamond layer being one of a nanocrystalline, microcrystalline or doped CVD diamond layer. 
   
   
       16 . The axial piston machine as recited in  claim 9 , wherein one of the first and second sliding sides spherically projects into the other sliding side.
