titleOfInvention | A kind of method for preparing tungsten alloy composite powder |
abstract | The invention relates to the technical field of nanoscale materials, in particular to a method for preparing tungsten alloy composite powder. The method includes: using dehydrated ammonium paratungstate, an erbium element compound and a zirconium element compound as raw materials, and using a co-deposition method to mix under an acidic condition to obtain a precursor of a tungsten alloy composite material; the erbium element compound and the zirconium element compound in the erbium salt are in the erbium element compound and the zirconium element compound. The molar ratio of zirconium element is 1:(0.5-5). The invention uses ammonium paratungstate, erbium element compound and zirconium element compound as raw materials to prepare tungsten alloy composite powder. The doping of zirconium element can hinder the growth of W particles and absorb free oxygen, and the particle size of the prepared tungsten alloy composite powder is reduced to 100-200 nm. The preparation method provided by the invention is simple and has strong operability, has excellent performance in the field of preparing oxide dispersion reinforced tungsten alloy powder, and is expected to be widely used in the high temperature application field as a plasma surface material in fusion reactors. |
