Implants with a calcium phosphate containing layer are disclosed. The implants, which can have a metallic character (e.g., made from a cobalt chromium alloy), can include a surface that is exposed to one or more formulations that results in a chemical and/or physical modification. In some instances, the modified surface is texturized so as to include a plurality of surface pits. The average pit size opening can range, for example, from 40 nm to about 10 &#x3bc;m, and can include a plurality of average pit sizes in some cases. The modified surfaces can promote growth of a calcium phosphate layer, which can be accelerated relative to conventional techniques. Other variations of such implant surfaces, and methods of producing similar implant surfaces, are also discussed.
