【摘要】 通过对Ｃｏ扩散阻挡层在ＣＶＤ过程中冶金行为的理论分析，建立了计算Ｃｏ扩散阻挡层临界厚度δ临的数学模型。指出：阻挡层厚度δ≥δ临是抑制Ｃｏ对金刚石沉积不良影响的必要条件。更多还原

【Abstract】 Some considerations of selecting Co diffusion barriers in synthesis of diamond on cemented carbide substrate containing Co are given.Based on the analysis of metallurgical behavior of the barrier in CVD process,a mathematical model for calculating the critical thickness δCr of Co diffusion barrier has been established.更多还原
