Abstract

The invention discloses a preparation method of a tungsten-nickel alloy target for electrochromic glass coating, comprising the following steps: (1) weighing each component according to the following weight percentages: high-purity tungsten powder 25-55%, high-purity nickel 25-55% powder and 10-25% high-purity tungsten trioxide powder; (2) Put the above components in a V-shaped mixer and mix them evenly to obtain mixed powder; (3) Put the above mixed powder in a vacuum The hot-pressing sintering mold is then loaded into a vacuum hot-pressing sintering furnace to 1400-1500° C. for pressure-vacuum sintering for 100-150 minutes, and the tungsten-nickel alloy target is obtained by cooling with the furnace. The tungsten-nickel alloy target prepared by the invention has high density and high purity.

Description

technical field [0001] The invention belongs to the technical field of alloy target preparation, and in particular relates to a preparation method of a tungsten-nickel alloy target used for electrochromic glass coating. Background technique [0002] The electrochromic glass used in civil Boeing 787 aircraft windows or high-end residential windows can change the color of the windows only by changing the current, so as to realize whether the light can pass through the windows to reach the room or the aircraft. The above-mentioned electrochromic glass needs to be coated with a tungsten-nickel alloy target. The discoloration effect and coating quality of the above-mentioned tungsten-nickel alloy targets prepared by the prior art are still not stable enough, resulting in low yield and high cost of electrochromic glass. Moreover, the existing methods for preparing the above-mentioned target materials often produce pollutants such as waste materials and waste acids. Contents of ...
