Abstract:
1. A method of producing ceramic layers on magnesium and its alloys, comprising the steps of: immersing an implant and a metal sheet into an aqueous electrolyte bath, said aqueous electrolyte bath consisting essentially of: ammoniac, diammonium hydrogen phosphate and urea, and wherein the implant is made of magnesium or its alloy; performing an anodic oxidation by passing a current between the implant, the metal sheet and through the aqueous electrolyte bath, wherein the implant is connected to a positive pole of a current source and the metal sheet is connected to a negative pole of the current source; applying a current density selected to form sparks on said implant, to thereby form a ceramic layer on said implant.
