Guest guest Posted November 15, 2001 Report Share Posted November 15, 2001 C+ is sintered. There was once the belief that that heating of the metal during the sintering decreased the wear resistance compared to unsintered. But then someone repeated the experiment and found the result was due to the relative machining precision between the units originally checked. When the units had similar machining accuracy to being with, the wear rates were the same. - Conserve Plus Anyone familiar with properties of Acetabular side of C+? I know the BHR has cast the texture in the rough side of Cobalt Chrome. I also read somewhere about C2K has Titanium Plasma spray on for rough surface. What about C+?

Guest guest Posted November 16, 2001 Report Share Posted November 16, 2001 I believe it is Cobalt-Chrome, they don't use hydroxyapatite (HA). I held one in my hand, apparently the sintering puts beads on the surface with a size and spacing give a good " grip " to ingrowing bone. They seemed more like dimples in a solid surface. - Re: Conserve Plus > C+ is sintered.

Guest guest Posted November 16, 2001 Report Share Posted November 16, 2001 Thanks again, . My concern was about Titanium. An OS told me that he liked to avoid it because where it comes in contact with bone, it turns the bone black. He told me it wasn't a good attribute, indicating reaction. > > C+ is sintered.
