Tantalum, a rare metal, is characterized by high melting point, high strength, corrosion resistance, high thermal stability, high thermal conductivity, excellent bioinert and biocompatible, and no radioactivity. Its unique physical and chemical properties make it play a unique application value in aerospace, aviation, electronics industry, medical implant and other fields.
For example, in aviation applications, tantalum materials can be formed to adapt to extremely high temperature working conditions, auxiliary engines, combustion chamber to improve combustion efficiency, and produce a greater thrust-to-weight ratio;
Porous tantalum in medical implants, high volume, low elastic modulus and high porosity on the surface of the typical characteristics of the coefficient of friction and good biocompatibility, and can relieve the stress shelter effect (that is, the implant high hardness in the adjacent bone does not have enough mechanical stimulation caused by osteoporosis), in favor of the postoperative recovery of the patients, And give the implant a longer life.
Tantalum is a refractory metal with a melting point close to 3000℃. Forming of this material requires high spot quality of equipment and requires stable energy output. In the process of tantalum forming, because of the forming stress, the parts are easy to crack, so it is necessary to optimize the forming process to avoid such problems.
