A biocompatible surgical implant for use in human beings and animals. The implant has a titanium or titanium alloy substrate having a surface that has been treated with phosphates. The surface treatment on the implant includes low temperature anodic phosphation of the titanium or titanium alloy substrate. Anodic phosphation changes or modifies the substrate surface through electrochemical reactions between the substrate, acting as an anode, and phosphate ions contained in an electrolyte solution, such as provided by an aqueous solution of phosphoric acid, and water molecules. The surface treatment imparts no significant change in the dimensions of the implant, thereby allowing the surgical implant substrate to be constructed to exact dimensions without having to account for the thickness of additional coatings being applied to the implant.
