采用辉光放电法在Ti-6Al-4V合金基体上制备了平均晶粒尺寸为8 nm的（Mo（x）Cr（1-x））（5）Si（3）纳米晶薄膜。采用纳米压痕法研究了Cr替代Mo对纳米晶（Mo（x）Cr（1-x））（5）Si（3）薄膜硬度、弹性模量和塑性变形能力的影响。结果表明，随着Cr含量的增加，纳米晶（Mo（x）Cr（1-x））（5）Si（3）薄膜的硬度略有下降。与此相反，塑性变形能力显着增加与Cr含量。
A series of nanocrystalline (Mo(x)Cr(1-x))(5)Si(3) films with an average grain size of 8 nm has been prepared on Ti-6A1-4V alloy substrates by glow discharge. The effect of substitution of Cr for Mo on the hardness, elastic modulus and plastic deformability of the nanocrystalline (Mo(x)Cr(1-x))(5)Si(3) film was investigated using the nanoindentation method. The results reveal that the hardness of nanocrystalline (Mo(x)Cr(1-x))(5)Si(3) films slightly decreases with increasing Cr content. In contrast, the plastic deformability significantly increases with increasing Cr content.
