Title:
CYLINDER LINERS WITH ADHESIVE METALLIC LAYERS AND METHODS OF FORMING THE CYLINDER LINERS
Document Type and Number:
WIPO Patent Application WO/2014/163911
Kind Code:
A3
Abstract:
A coated cylinder liner 20 comprises a wear resistant layer 22, such as a DLC coating, and a metallic adhesive layer 24, such as chromium or titanium, deposited on an inner surface 26 thereof. The layers 22, 24 each have a thickness tw, ta varying by not more than 5% along at least 70% of the length of the inner surface 26. The metallic adhesive layer 24 is deposited by sputtering a consumable metallic electrode 28 onto the inner surface 26. The sputtering can be magnetron sputtering. The consumable metallic electrode 28 can include a hollow opening 40 with orifices 50 for providing a carrier gas into the deposition chamber 52. In addition, the inner surface 26 of the cylinder liner 20 can provide the deposition chamber 52 by sealing a first opening 36 and second opening 38 of the cylinder liner 20.
