Abstract : The patent discloses a method for producing a machinable titanium piece having on its surface a thin layer of a noble metal selected from the group consisting of gold and silver and between said layer and titanium base a thicker alloy concentration gradient of titanium and said noble metal. The method comprises the steps of: electroplating the piece with noble metal, gradually and strongly heating the electroplated piece in vacuo from room temperature, holding the electroplated piece in vacuo in its strongly heated state, and allowing the piece to cool gradually in vacuo. This coating produces the lubricating action for antifriction and antiwear surfaces of titanium.
