| 摘 要： | 采用浸涂及烧结工艺制备了达克罗防腐涂层,对其表面组织结构及其与镀锌、镀铝涂层的防腐蚀性能对比进行了研究.结果表明,锌、铝、铬等元素在达克罗涂层中分布均匀,片状的锌粉和铝粉层叠包埋在无定形的铬酸盐粘结物中,其耐腐蚀性能优于热镀锌层,略低于热浸铝镀层,与基体接合强度低于热浸铝.

| Abstract: | The Dacromet technology,which is a potential surface treatment method,has achieved extensive application in automobile industry.The Dacromet coating is prepared through dipping & curing process,and the microstructure and anticorrosion performance of zinc,aluminum galvanized specimens are comparatively investigated.The results shows that the zinc,aluminum,chromium distributed evenly and Zn/Al flakes overlapped and embedded in amorphous chromium binder in Dacromet coating which anticorrosion is superior to hot dip galvanized but slightly inferior to hot dip aluminum coating with lowered adhesion,its adhesive ability to matrix is weaker than that of aluminum coating. |
