Interference fit assembly, a thermal compensation arrangment of an injection valve and method for producing an interference fit assembly

摘要

Interference fit assembly (10) of a first metal part (12) and a second metal part (18), wherein the first metal part (12) has a recess (14) with an inner contact surface (16), and the second metal part (18) has an outer contact surface (20) being coupled to the inner contact surface (16) by an interference fit. At least one of the contact surfaces (16, 20) has a surface layer (22) comprises a diamond-like carbon layer (24). Method for producing an interference fit assembly (10) by applying the surface layer (22) on at least one of the contact surfaces (16, 20) by a Physical Vapor Deposition (PVD) or a Chemical Vapor Deposition (CVD) process with the surface layer (22) having the diamond-like carbon layer (24).
