| 摘要: |
| 综述了纳米复合薄膜的硬度增强特性和热稳定性、在高温条件下(≥1 000 ℃)的抗氧化性和热稳定性、在X射线下呈非晶态的薄膜在高温条件下的热稳定性、以及具有高韧性新型硬质纳米复合薄膜的相关性能。这些新型高韧性硬质纳米复合薄膜具有较低的等效弹性模量E*（H/ E*>0.1），高弹性恢复系数(We≥60%)，优异的摩擦学性能，以及良好的抗断裂能力。等效弹性模量E*=E(1-ν2)，E为弹性模量，ν为泊松比。 |

| Abstract: |
| The paper reports the enhanced hardness of nanocomposite coatings, their thermal stability, protection of the substrate against oxidation at temperatures above 1 000 ℃, Xray amorphous coatings thermally stable above 1 000 ℃ and new advanced hard nanocomposite coatings with enhanced toughness, which exhibit low values of the effective Young's modulus (E*) satisfying the condition H/E*>0.1, high elastic recovery We≥60%, strongly improved tribological properties, and enhanced resistance to cracking. The trends of next development of hard nanocomposite coatings are briefly outlined. |
