CERAMIC COMPONENT FOR MAGNETRON
To provide an alumina component for a magnetron that forms a uniform plating layer on a metallized layer formed on a terminal portion and a ring portion.SOLUTION: In a magnetron ceramic component in which a terminal portion metallized layer and a ring portion metallized layer are formed on a terminal portion and a ring portion formed on the surface of a ceramic component body, respectively, and a terminal portion nickel layer and a ring portion nickel layer are formed on the surfaces of the terminal portion metallized layer and the ring portion metallized layer, respectively, the thicknesses of the terminal portion nickel layer and the ring portion nickel layer are 1.0 μm or more, and the thickness of the nickel layer at a place which is half the distance from a terminal portion hole to a terminal portion end in a direction to another terminal portion hole has a ratio of 0.95 or more to the thickness of the nickel layer at a place which is half the distance from a terminal portion hole to a terminal portion end in an opposite direction to a direction to another terminal portion hole.SELECTED DRAWING: Figure 1
【課題】端子部およびリング部に形成したメタライズ層に均一なめっき層を形成するマグネトロン用アルミナ部品を提供する。【解決手段】セラミックス部品本体の表面に形成された端子部およびリング部にそれぞれ端子部メタライズ層およびリング部メタライズ層を形成し、この端子部メタライズ層およびリング部メタライズ層の表面にそれぞれ端子部ニッケル層およびリング部ニッケル層を形成したマグネトロン用セラミックス部品において、前記端子部ニッケル層およびリング部ニッケル層の厚さがそれぞれ１．０μｍ以上であり、端子部穴から他の端子部穴方向の端子部端までの距離の１／２にあたる箇所のニッケル層の厚さが、他の端子部穴方向との逆方向の端子部端までの距離の１／２にあたる箇所のニッケル層の厚さに対するに比が０．９５以上とする。【選択図】図１
