Embodiment Construction

[0031] The following are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0032] A method for preparing a titanium-aluminum alloy target, comprising a powder mixing step, a filling step, a cold isostatic pressing step, a welding sheath degassing step, a hot isostatic pressing step, a cutting step, an alloying diffusion heat treatment step and a machine Machining and trimming steps.

[0033] Titanium aluminum targets are widely used in the fields of tools and decorative coatings. Titanium-aluminum alloy has low density, high strength and hardness, and has good wear resistance. Coating a layer of titanium-aluminum alloy on the surface of ordinary knives can enhance the surface hardness of the knives, make the knives sharper, and effectively extend the use time of the knives . Under different atmospheres, titanium-aluminum alloy targets can form decorative films of different colors such as yellow, b...

The preparation method comprises a powder mixing step, a filling step, a cold isostatic pressing step, a welding sheath degassing step, a hot isostatic pressing step, a slitting step, an alloying diffusion heat treatment step and a machining finishing step. The preparation method is simple in control, low inprocessing cost and high in processing efficiency.

Description

technical field [0001] The invention relates to the technical field of a titanium-aluminum alloy target, in particular to a preparation method of a titanium-aluminum alloy target. Background technique [0002] At present, the production process of titanium aluminum alloy target mainly includes smelting casting and powder alloying and sintering. [0003] When the smelting process is used to manufacture titanium-aluminum targets, air bubbles, porosity and segregation are prone to occur during the pouring process; titanium-aluminum alloys are difficult to heat process, casting defects are difficult to remove, density is difficult to increase, and the yield is low. At the same time, it is difficult to ensure the uniformity of the composition and structure in the titanium-aluminum alloy, which leads to the inability to guarantee the stability of the quality of the titanium-aluminum target. [0004] Powder alloying and then sintering, firstly mix aluminum powder and titanium powd...
