Embodiment 1
[0031] like figure 1 As shown, this embodiment includes the following steps:
[0032] Step 1. Mixing: According to the nominal composition of the target product 90WNiCu alloy, tungsten powder, cobalt powder, nickel powder and copper powder are selected as raw materials to weigh and put into an inclined mixer for dry grinding and mixing to obtain mixed powder; the The ratio of ball to material mixed by dry grinding is 4:1, and the time is 7h;
[0033]Step 2, granulation: adding polyethylene glycol to the mixed powder obtained in step 1, then wet grinding and mixing, and then using a spray drying tower for spray drying granulation to obtain 40-120 mesh granules; The added mass of ethylene glycol is 2.0% of the mass of the mixed powder; the wet grinding and mixing are carried out in a ball mill, the medium used is ethanol solution, the ratio of ball to material is 3:1, and the time of wet grinding and mixing is 12h;
[0034] Step 3, pressing and forming: the granulated material...
