| titleOfInvention | A kind of high temeperature chemistry container tantalum material and preparation method thereof |
| abstract | The invention discloses a kind of high temeperature chemistry container tantalum materials of high temeperature chemistry technical field and preparation method thereof.In the tantalum material, tantalum matrix is grouped as by the group of following mass percentage：99.84% 99.90%Ta, 0.04% 0.06%Hf, 0.06% 0.07%Zr, 0% 0.03%C；It is tantalum carbon-coating in the outer layer of tantalum matrix, thickness is 20 80 μm, and specific preparation method is：It adds the elements such as hafnium, zirconium and carbon and carries out tantalum microalloying, through carburizing pre-treatment, exemplar is subjected to vacuum carburization processing, vacuum level requirements<10 ‑3 Pa, carburizing temperature are 1000~1600 DEG C, keep the temperature 1 10h, 4000 6000Pa of furnace pressure, and carry out surface grinding to exemplar.The present invention adds hafnium, zirconium in pure tantalum, can reduce the wetting property of tantalum matrix, while reducing the solubility of oxygen in alloy, improves the thermal stability of alloy；By Carburization Treatment, alloy surface forms the tantalum carbon-coating of excellent anti-corrosion performance, wetting property difference；Tantalum carbon-coating is combined closely with matrix, solves the problems, such as that tantalum carbon-coating is easily rupturable and falls；It is processed into easily separated with metal target after high temeperature chemistry container, service life is longer. |
