P=100---300MPa
T=1500---2500℃
大気圧と比較して、飽和雰囲気の圧力の増大が、処理下にある製品表面上の吸収過程の強化を促進し、その際、より強力に含浸剤濃度を増加させる。このことは、濃度勾配の増大を導き、したがって拡散過程の促進を導く。それに加えて(Sivertの法則)、飽和環境の圧力が増大すると、金属中の窒素の溶解性が高まり、それが、硬化させる製品表面上の脆い窒化物相の発達を抑制する。
- 最小のイオン半径(容易に拡散する)、
- 水素様スペクトルを得ることが可能、
- 近い量子数が、所要の磁気及び軌道モーメントをもたらす、
- 所要の核構造が、ポジトロニウムを作り出ことを助長する、
- 所要のエネルギーレベル距離、その間に対応するガンマ-量子エネルギー(2m0c2、式中m0---電子質量、c---真空における光の速度)。
