方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a magnetron anode structure in which the anode cylinder, the vane, and the strap ring that electrically connects the vane's equipotential point are both made of aluminum or an aluminum-based alloy. Regarding the manufacturing method.
現在、最も多く用いられているマグネトロンの
陽極構体は、陽極円筒も、ベインも、ストラツプ

熱し、銀ろう付けするのが一般である。 In the anode structure of the magnetron that is most commonly used today, the anode cylinder, vane, and strap ring are all made of copper.The connection between the vane and the strap is made by first silver-plating the strap ring, or by silver-plating the strap ring in advance. Alternatively, it is common to supply silver paste to the joint and heat it in a hydrogen or inert atmosphere to perform silver brazing.

するような粉末ろう材は、開発されていない。 Although the above-described anode structure has no particular disadvantages in terms of characteristics, it is heavy and the material cost is high. In order to solve these problems, aluminum or an aluminum-based alloy is the most suitable material to replace copper with a light weight, relatively high conductivity, and low cost. However, aluminum easily forms an oxide film, is difficult to form a solid solution with heavy metals, and when heated together with copper will form a brittle intermetallic compound at the joint, and if even some moisture remains during brazing, it may cause local corrosion. It was a difficult metal to braze, as it caused a lot of damage. In recent years, aluminum-silicon based alloy solders have been developed and reliable brazing has become possible. However, a powder brazing material equivalent to the above-mentioned silver soldering paste has not been developed for use in brazing aluminum.

Both sides or one side of an aluminum or aluminum-based alloy plate material is coated with an aluminum-silicon alloy brazing material in advance by a specialized company. The vane and the strap ring are brazed by placing the ring in a predetermined position within the groove of a vane made of aluminum or an alloy mainly composed of aluminum, and heating the joint in a vacuum or by applying flux to the joint. .
