| 中文摘要: |
| 目的 系统研究 CuNiIn 和 CuInO2 的晶体结构、体模量、剪切模量、杨氏模量、泊松系数、韧性、热膨胀系数、残余应力等物理参量，阐明 CuNiIn 涂层中生成的其他复合化合物—CuInO2 对 CuNiIn 机械性能的影响作用机制。 方法 采用基于密度泛函理论的第一原理，弹性常数采用应力-应变方案，体模量、剪切模量、杨氏模量采用 Voigt-Reuss-Hill 方法计算。 结果 CuNiIn 和 CuInO2均为机械稳定结构，CuNiIn 和 CuInO2的体模量、剪切模量、杨氏模量、泊松系数分别为 118.2 GPa， 13.7 GPa， 39.6 GPa，0.44 和 119.0 GPa， 36.8 GPa， 100.1 GPa， 0.36。化合物 CuInO2的机械模量较 CuNiIn 高，韧性较差，热膨胀系数较低，涂层的残余应力较高。 结论 喷涂工艺不适，或 CuNiIn 涂层服役过程中生成的 CuInO2对微动磨损 CuNiIn 涂层服役性能有不利影响。 |

| Objective In this investigation, the crystal structure, bulk modulus, shear modulus, Young modulus, Poisson ratio, toughness, thermal expansion coefficients and residual stress of CuNiIn and CuInO2 were inspected systematically, and the influencing mechanism of the material of CuInO2 in CuNiIn coatings on the mechanism performance of CuNiIn was elucidated. Methods Elastic constants were obtained with stress-strain method using the first principles density function theory. Bulk, shear and Young modulus were obtained using Voigt-Reuss-Hill methods. Results The study indicated that CuNiIn and CuInO2 were mechanically stable structures. The bulk modulus, shear modulus, Young modulus and poisson ratio for CuNiIn and CuInO2 were 118.2 GPa, 13.7 GPa, 39.6 GPa, 0.44, and 119.0 GPa, 36.8 GPa, 100.1 GPa, 0.36, respectively. The mechanical modulus of CuInO2 was higher than that of CuNiIn. The toughness of CuInO2 was poorer, the thermal expansion coeffieent was lower and the inner residual stress of CuInO2 was higher than those of CuNiIn. Conclusion Improper spray process parameters or the CuInO2 produced during the service process had negative effects on the service performance of CuNiIN fretting wear coatings. |
