摘要

这项工作是通过多靶材交替溅射沉积（CrNbTiAlV）CN/MoN 涂层。随着调制周期从 420 纳米减小到 110 纳米，(CrNbTiAlV)CN/MoN 多层涂层的硬度和弹性模量逐渐增加；然而，调制周期为 50 纳米的多层涂层的硬度和弹性模量值却有所下降。随着调制周期的减小，MoO3 碎片的特征从大片状变为平滑转移摩擦层，然后再变为小颗粒。调制周期为 110 nm 的涂层在 500°C 时的最小摩擦系数和磨损率分别约为 0.11 和 4.4 × 10-6 mm3/(N m)。这可归因于它具有最佳的抗塑性变形能力，并倾向于形成光滑的转移摩擦涂层。

Effect of modulation period on the mechanical and tribological behavior of (CrNbTiAlV)CN/MoN coatings

This work is to deposit (CrNbTiAlV)CN/MoN coatings by alternating sputtering with multiple targets. The hardness and elastic modulus of the (CrNbTiAlV)CN/MoN multilayer coatings gradually increase with the decreasing of the modulation period from 420 to 110 nm; however, the values decrease on the multilayer coating with a modulation period of 50 nm. As the modulation period decreases, the characteristic of MoO₃ debris changes from large flakes to smooth transfer tribolayers and then to small particles. The coating with a modulation period of 110 nm has a minimum friction coefficient and wear rate of about 0.11 and 4.4 × 10^–6 mm³/(N m) at 500°C, respectively. This can be attributed to the fact that it has the best resistance to plastic deformation and tends to form smooth transfer tribolayers.
