摘要

The method for producing antimicrobial surface of an object, comprises producing a porous surface, storing an antimicrobial effective first and second metal in the resulting pore (3), where the second metal has a higher standard potential than the first metal within the electro-chemical voltage range, closing the pores, and removing parts of the surface for exposing the metals present in the pores. The porous surface is produced by means of an anodic oxidation. The storage of the first and second metal is carried out by means of an electrolytic deposition. The method for producing antimicrobial surface of an object, comprises producing a porous surface, storing an antimicrobial effective first and second metal in the resulting pore (3), where the second metal has a higher standard potential than the first metal within the electro chemical voltage range, closing the pores, and removing parts of the surface for exposing the metals present in the pores. The porous surface is produced by means of an anodic oxidation. The storage of the first and second metal is carried out by means of an electrolytic deposition, a precipitation under use of a chemical reducing agent or a sol-gel process. A blasting technique is used for removing the surface. A ball-blasting technique is applied with glass beads as the blasting technique. A layer of 1-5 mu m is removed from the surface. The pore has a depth of 5-30 mu m and a diameter of 15-30 nm. The surface consists of aluminum, magnesium and/or titanium. An independent claim is included for an object having a surface.
