... When reactive gases are passed through the discharge atmosphere surrounding the material to be treated, they react with the base material and create a layer of nitrides or carbides on the surface. This is generally called ion treatment, and depending on the purpose, it is called ion nitriding, ion carburizing, etc. In the discharge atmosphere, the oxide film on the surface of the material to be treated is removed by ion bombardment (sputtering effect), which has the advantage that it can be applied to materials that are difficult to treat using conventional methods, such as high-chromium steel. ... *Some of the terminology that refers to "ion treatment" is listed below.

… 被処理材をとりまく放電雰囲気の中に反応性ガスのみを通過させると,これが母材と反応して,表面に窒化物や炭化物の層をつくることができる。これを一般にイオン処理と呼び,目的に応じてイオン窒化,イオン浸炭などという。放電雰囲気内ではイオン衝撃により被処理材表面の酸化物皮膜が除去される(スパッタリング作用)ので,高クロム鋼のように従来の方法では処理困難な材料にも適用できる利点がある。… ※「イオン処理」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
