Abstract

Interference fit assembly of a first metal part and a second metal part, wherein the first metal part has a recess with an inner contact surface, and the second metal part has an outer contact surface being coupled to the inner contact surface by an interference fit. At least one of the contact surfaces includes a surface layer including a diamond-like carbon. In a method for producing an interference fit assembly the surface layer is applied on at least one of the contact surfaces by a Physical Vapor Deposition or a Chemical Vapor Deposition process with the surface layer having the diamond-like carbon.
