COBALT CHROME COATED TITANIUM IMPLANT |
| 摘要 |
An orthopedic implant has a prosthetic joint component made, for example, of polyethylene and another component made of a titanium or titanium alloy substrate. The substrate has a first bearing surface coated with a coating made of a cobalt-chromium molybdenum alloy. The bearing surface slidably receives a second bearing surface of the prosthetic joint component. The cobalt-chromium molybdenum alloy coating forming the first bearing surface is made up of hexagonal close packed (HCP) grains having a columnar structure with a length of about 1 μm and a width of about 0.1 μm with the length of each HCP grains being oriented generally perpendicular to the titanium substrate bearing surface. |

1. A method for manufacturing a prosthetic implant comprising:
providing a substrate comprising titanium; coating a surface of the substrate with a cobalt chromium molybdenum alloy by multi-arc physical vapor deposition to produce a majority of grains having a hexagonal close pack (HCP) phase; polishing the cobalt chromium molybdenum HCP coating. |
