Description
Technical field
The present invention relates in technical field of metal material manufacture, specifically a kind of thorium tungsten-rhenium wire and manufacture method thereof that is specially adapted to the coiling microwave oven magnetic.
Background technology
In the prior art, the magnetron that microwave oven is used adopts the thoriatde-tungsten wire coiling to form.For improving the stability of magnetron, require the magnetron with the thoriatde-tungsten wire coiled is carried out carbonizing treatment.Carbonization is that the magnetron that formalizes and assemble is placed in the steam of hydrocarbon polymer, be heated to 2200-2500 ℃, when the tungsten of hydrocarbon vapor and high temperature contacts, decomposite carbon and hydrogen, carbon is attached to the surface of thoriatde-tungsten wire, with tungsten formation wolfram varbide and to the tungsten internal divergence.Because the thorium atom is larger than tungsten with the bonding force of wolfram varbide, the thoriatde-tungsten wire of carbonization is under working temperature, and wolfram varbide is reduced into the thorium atom with Thorotrast, thereby makes the thoriatde-tungsten wire surface form a stable monatomic tectum, makes it to produce stable electron emission.
But, adopt the microwave oven magnetic of traditional thoriatde-tungsten wire preparation in the process of carbonization, because carbonization temperature is higher than the recrystallization temperature (approximately 2000 ℃) of thoriatde-tungsten wire, the tungsten grain coarsening rate is fast, cause the fragility of thoriatde-tungsten wire to increase, so that brittle failure easily occurs, reduce the yield rate in the microwave oven magnetic production process in the assembling of microwave oven magnetic and transportation.In addition, because traditional thoriatde-tungsten wire creep resisting ability is low, adopt the microwave oven magnetic of traditional thoriatde-tungsten wire preparation in use can deform, shorten its work-ing life.
