Medical titanium material The main manufacturing processes of PZT include powder metallurgy, melting metallurgy and electrochemical deposition. These three processes have different characteristics and application scope in the manufacturing process of medical titanium materials.

Powder metallurgy is a method to prepare metal powder into materials. First, titanium powder is mixed with other metal powders, and then through cold pressing, sintering, heat treatment and other steps, titanium powder is formed into a material with certain shape and mechanical properties. The medical titanium materials made by powder metallurgy can have high mechanical properties and good biocompatibility. In addition, the method can also produce medical devices and implants with specific shapes and sizes, such as artificial hip joints and bone plates.

Melt metallurgy is a method of manufacturing materials by casting, extrusion, forging, etc. after the metal is heated to the molten state. In the manufacturing process of medical titanium materials, melting metallurgy is often used to prepare large, complex shaped medical devices and implants. Medical titanium materials with different properties can be obtained by adjusting the temperature and speed during melting and solidification. Compared with powder metallurgy, melting metallurgy can produce medical titanium materials with higher mechanical properties and excellent corrosion resistance.

Electrochemical deposition is a method of depositing metal on electrode by electrolytic reaction. The electrochemical deposition of medical titanium materials can be based on two different mechanisms, namely, anodic oxidation and electrodeposition. Anodic oxidation method is suitable for preparing medical titanium materials with ceramic coating, which has good biocompatibility and wear resistance. The electrodeposition method is suitable for preparing the surface of medical titanium materials with nano and micro structures. This structure can increase the interface contact area between medical titanium materials and biological tissues, improve biocompatibility and promote bone tissue repair.

In addition to these traditional manufacturing processes, some new manufacturing processes have emerged in recent years, such as 3D printing technology. 3D printing technology can produce medical titanium materials with complex shapes and fine structures by melting titanium powder layer by layer. Compared with the traditional manufacturing process, 3D printing technology has the advantages of short manufacturing cycle, low production cost and strong customization. Therefore, 3D printing technology has broad application prospects in the manufacturing field of medical devices and implants.
