- 摘要:
- 针对电镀硬铬微裂纹多、耐蚀性差的特点,为了解决油缸活塞杆长效使用的问题,采用封闭技术对单层电镀硬铬、乳白铬 / 硬铬双层电镀铬进行后处理以提高镀铬层耐蚀性。采用 目视、扫描电镜、光学显微镜等方法观察 宏观腐蚀形貌、微观表面形貌、截面形貌,对比分析了封闭处理前后的单层和双层镀铬层户外暴露实验和盐雾实验的耐蚀性能。结果表明:相对于封闭处理前,封闭处理后的单层和双层镀铬的耐蚀性较好,封闭处理双层电镀铬耐蚀性远优于封闭处理单层电镀硬铬。经过封闭处理双层电镀铬层能够显著阻碍腐蚀向 点蚀孔 四周扩展,其耐蚀性得到了显著改善,能够满足在热带海洋大气环境中长期使用的要求。
- Abstract:
- : In view of abundant micro-crack and low corrosion resistance of chromium-electroplating coating , a method was introduced to solve the long service of the cylinder piston rod. The post-treatment of sealing technique was employed to improve the corrosion resistance of the single and double layer of chromium-electroplating coating. The corrosion resistance of the single layer and double laye of Cr coatings with and without the sealing treatment after outdoor exposure test and salt spray test was compared and analyzed by macro , micro-morphology and section morphology , using visual observation , scanning electron microscope ( SEM ) and optical microscope ( OM ) . It showed that the corrosion resistance of the single and double layer of Cr coatings was improved after the sealing treatment , and the corrosion resistance of the double layer of Cr duplex coating was much better than that of the single layer after the treatment. The double layer of Cr coating after sealing treatment can restrain the corrosion diffusion around the pitting hole. The corrosion resistance of the double layer of Cr coating after sealing treatment was improved remarkably , which can survive a long term in the tropical marine environment.
