【摘要】 对H13钢（4Cr5MoSiV1）在不同温度下进行辉光离子渗氮试验,对渗氮后试样的硬度与渗氮前后试样的质量进行了测量。计算出氮在其中的扩散激活能为131.48 kJ/mol,793 K时氮在其中的扩散系数为2.34×10^-12m²/s。更多还原

【Abstract】 Specimens of H13 steel（4Cr5MoSiV1）were glow plasma nitrided at diferent temperature.The Microhardness of the nitrided layers was measured.The mass of non-nitrided and nitrided Specimens was also detected.The activation energy for nitriding is 131.48 kJ/mol for corresponding specimen on the basis of （?）ⁿ=K₀·e^-G/RTτ.The diffusion coefficient is 2.34×10^-2m²/s at 793 K by Fick’s first law.更多还原
