摘要： The present invention relates generally to a bio-degradable implant based on magnesium having a reduced corrosion rate and to a method for the production of such an implant. It is a a method for treating a surface of a bio-degradable metallic implant comprising the following steps: providing a dispersed system comprising a colloid-dispersed apatite and adding an apatite powder to the dispersed system, subjecting an implant to the dispersed system such that a surface of the implant which is to be treated is immersed in the dispersed system wherein the implant comprises a magnesium based alloy, applying an AC voltage difference between the implant as a first electrode and a second electrode positioned in the dispersed system for generating a plasma electrolytic oxidation on the immersed surface of the implant so that the immersed surface is converted to an oxide film which is at least partially covered by apatites formed by the colloid-dispersed apatite and the apatite powder. The evolution of corrosion induced hydrogen gas evolution is decreased and osseointegration is improved.

摘要： A method of manufacturing a metal material is provided. The method includes steps of manufacturing a metal material in which oxygen atoms are dispersed, and forming a protective coating on a surface of the metal material by using an anode oxidation treatment, wherein the oxygen atoms in the metal material are supplied to the surface of the metal material during the anode oxidation treatment, so that the metal material and the protective coating are interface-bonded to each other substantially without pores therebetween or without an interface layer in which pores are formed, thereby improving corrosion resistance, as compared to a protective coating formed on a surface of a metal material in which oxygen atoms are not dispersed.

摘要： The present invention relates to a process for producing a coating on the surface of a substrate by plasma-electrolytic oxidation. Improved corrosion protection for lightweight metals, in particular for magnesium or magnesium alloys, is achieved by the process. Furthermore, biocompatible protective layers can also be produced on these materials, with the option of controlling degradation of the substrate. The layers are amorphous. They are produced by plasma-electrolytic oxidation in which the substrate is dipped as electrode together with a counterelectrode into an electrolyte liquid and a sufficient electric potential for generating spark discharges at the surface of the substrate is applied, wherein the electrolyte comprises clay particles dispersed therein. Substrates can therefore be any machine components, automobile components, railroad components, aircraft components, ships' components, etc., or bioimplants such as bone replacement materials or medical bone screws made of a lightweight metal such as magnesium or a magnesium alloy.

摘要： A two-step process for the coating of magnesium and its alloys is disclosed. The first step comprises immersing the magnesium workpiece in an aqueous solution comprising about 0.2 to 5 molar ammonium fluoride having a pH of about 5 to 8 and a temperature of about 40.degree. to 100.degree. C. The second step is an electrochemical treatment of the pretreated article in an aqueous electrolytic solution having a pH of at least about 12.5 and which solution comprises about 2 to 12 g/L of a aqueous soluble hydroxide, about 2 to 15 g/L of a fluoride-containing composition selected from the group consisting of fluorides and fluorosilicates, and about 5 to 30 g/L of a silicate. This process results in a superior coating which has increased abrasion and corrosion resistance.
