提供钨和镍混合粉末（质量比为9.95:1至10.05:1），对所述钨和镍混合粉末采用冷等静压工艺，对钨、镍混合粉末和不锈钢空心管进行首次致密化和预成型，形成半致密的钨、镍混合粉末和不锈钢初始坯料，使后续的热等静压工艺对钨、镍混合粉末和不锈钢初始坯料可以进行更好的致密，以较好的对靶材的部分表面进行喷砂处理，同时不影响到靶材的其他不需要喷砂的部分，获得镍钨合金靶材。

Provide tungsten and nickel mixed powder (the mass ratio is 9.95:1 to 10.05:1), the cold isostatic pressing process is adopted for the tungsten and nickel mixed powder, and the tungsten and nickel mixed powder and stainless steel hollow tube are densified and preformed for the first time to form semi dense tungsten and nickel mixed powder and stainless steel initial blank, so that the subsequent hot isostatic pressing process can better compact tungsten, nickel mixed powder and stainless steel initial blank, The nickel tungsten alloy target can be obtained by better sandblasting some surfaces of the target without affecting other parts of the target that do not need sandblasting.

The tungsten and nickel mixed powder (mass ratio is 9.95:1 to 10.05:1) is provided, the tungsten and nickel mixed powder is subjected to cold isostatic pressing process, and the tungsten and nickel mixed powder and stainless steel hollow tube are densified and preformed for the first time to form semi-dense tungsten and nickel mixed powder and stainless steel initial blank, so that the subsequent hot isostatic pressing process can better densify the tungsten and nickel mixed powder and stainless steel initial blank, so as to better target materials.
