摘要 采用冷喷涂技术在高强钢(300M)表面制备铝锌复合涂层作为抗腐蚀涂层.利用扫描电镜(SEM)、能量色散谱(EDS)、显微硬度测试仪研究涂层的微观形貌结构及显微硬度;综合涂层中性盐雾加速实验及户外暴晒实验结果并与300M基材进行对比,对涂层的抗腐蚀性能开展全面评价;考核冷喷涂后对300M钢基材疲劳性能影响.结果表明:冷喷涂铝锌复合涂层结构致密,平均孔隙率为0.8%,显微硬度为59.8HV0.025,中性盐雾实验1000h时无腐蚀,即使涂层破损也可以达到770h,户外大气暴晒实验12个月后涂层表面无腐蚀发生,冷喷涂后对300M钢基材的疲劳性能没有影响.

Abstract:Al/Zn coatings could be deposited by cold gas dynamic spray on high-strength steel (300M) surface. The morphology and microstructure of coating were analyzed by scanning electronic microscope (SEM),energy dispersive spectroscopy (EDS) and microhardness tester. The corrosion resistance was investigated by neutral salt-spray accelerated test and atmospheric exposure test and fatigue test results of Al/Zn coatings were compared with 300M substrate. All the results indicate that Al/Zn coatings porosity is 0.8%, the microhardness is 59.8HV0.025, the salt spray resistance reaches 1000h and it can reach 770h even the coatings fails, the atmospheric exposure test achieves 12 months and no influence over 300M substrate fatigue.
