摘　　要： 　为了探讨纳米ZnO(n-ZnO)对火焰喷涂尼龙1010涂层力学及抗老化性能的影响,利用电子拉力机和紫外光辐照箱对火焰喷涂尼龙1010 n-ZnO复合涂层的力学性能及耐老化性能进行了测试。结果表明,当复合涂层配比为m(PA1010):m(n-ZnO)=100:1.5时,复合涂层综合性能较佳,涂层自拉伸强度为41.92MPa;涂层与基体结合强度为41.68MPa;涂层经10天紫外线老化后,强度保持率分别为97%和87.2%。纳米ZnO能够显著提高涂层力学性能和抗老化性能。 The mechanical properties and UV resistance of flame spraying Nylon1010/nanometer ZnO coatings were studied by universal testing instruments and radiation exposure unit. The results showed that when PA1010 was filled with 1.5% n-ZnO, the properties of the coating were the　best. The adhesion stress of coating and substrate was 41.68 MPa. The self-strength of the coating was 41.92 MPa. After 240 hours UV radiating, the adhesion stress of coating and substrate was 35.13 MPa, while the self-strength of the coating was 36.89 MPa.
