    摘要:

    介紹了鋼中稀土對離子氮化、離子硫氮碳共滲及氣體滲碳的影響，提出了鋼中稀土促滲的“氣團－通道”模型。指出稀土是通過直接和間接作用來加速氮、碳的擴散與氮、碳化物的形成。因此，鋼中稀土具有顯著的促滲作用，并提高滲層硬度。

    Abstract:

    The effects of the rare earths in steels on the plasma nitriding, plasma sulphur-carbonitriding and gas carburising have been studied. An atomistic model based on electron affinities is proposed for the catalytic effect of the rare earths. It is pointed out that the rare earths accelerate the diffusion of carbon and nitrogen atoms, and the formation of nitride, carbide and carbonitride through direct and indirect actions. Therefore, the rare earths in steels have a significant catalytic effect during those treatments, and make the treated cases harder.
