Description
Technical field
The present invention relates to a kind of coloring apparatus, especially relate to a kind of titanium alloy anodic oxidation and coloring device.
Background technology
Because titanium has that density is little, intensity is high, stable chemical performance and advantage such as corrosion-resistant, therefore since the eighties in 20th century, the titanium material begins to be applied to removable partial denture to be made, and is gradually improved in clinical application.Titanium or titanium alloy is used to medical field because of having good biocompatibility again, and its good biocompatibility is the dense oxidation film that comes from the surface.In a single day titanium is exposed to the oxide film protection layer that just can form one deck densification in the air rapidly, and its thickness is 2～60nm.Oxide film has two big functions: 1) stop titanium matrix metal to body fluid environment release metal ions; 2) structure of zone of oxidation and hydration characteristics make it to be exposed to body fluid generation aquation, promote specific protein in surface adsorption, integrate thereby form bone.Yet the oxide film that forms naturally in air can not meet the demands because rete is unstable and thickness is too thin.In order to improve the performance of rete, carry out surface modification to titanium alloy.The method of surface modification is a lot, and anodic oxidation is the most frequently used a kind of method.
