[0003] Using waste titanium Ti6Al4V as a soluble anode, it is produced by electrolysis in an alkali metaloxide salt system (Gao Yupu, Guo Naiming, Rare Metals, 1997). Besides being very low, the main disadvantage is that the aluminum content of different particle sizes is different, the smaller the particle size, the higher the Han Liangliang, and with the increase of the anode recovery rate, the aluminum content increases, resulting in unstable aluminum content in the alloy powder, and due to the Refine the grains, resulting in too fine grains and unqualified oxygen content, which cannot meet the requirements for manufacturing structural parts
However, this method adopts the method of separately refining and alloying titanium and aluminum to produce metalpowder, the alloying is not complete, the cathode product in the form of powder is not easy to separate, and it is easy to remain in the molten salt, and the salt inclusion rate of the product is extremely high

Abstract
The invention discloses a preparation method of a titanium-aluminum alloy. The preparation method of the titanium-aluminum alloy comprises the step that an anode is prepared from titanium, a cathode is prepared from molten aluminum, and the anode and the cathode are electrolyzed in a molten saltelectrolyte, so that the titanium-aluminum alloy is prepared. According to the preparation method of the titanium-aluminum alloy, molten aluminum is used for preparing the cathode and is alloyed in the molten state, and the titanium-aluminum alloy obtained after alloying deposits to the bottom of a crucible and thus can be easily separated; and the titanium-aluminum alloy has the advantages of being high in mechanical property, smooth in coarse alloy surface, easy to clean, low in impurity content,and beneficial to next processing.
Description
technical field [0001] The invention relates to a preparation method of titanium-aluminum alloy, which belongs to the technical field of alloy processing. Background technique [0002] Titanium alloy has low density, high specific strength, good corrosion resistance, high temperature creep resistance and welding performance, and excellent biocompatibility. It is widely used in aerospace, navigation, chemical industry, power generation, automobile, sports and leisure, medical treatment and other fields. There are several types of titanium alloys produced by molten saltelectrolysis: [0003] Using waste titanium Ti6Al4V as a soluble anode, it is produced by electrolysis in an alkali metaloxide salt system (Gao Yupu, Guo Naiming, Rare Metals, 1997). Besides being very low, the main disadvantage is that the aluminum content of different particle sizes is different, the smaller the particle size, the higher the Han Liangliang, and with the increase of the anode recovery rate,...
