摘要
在钢构件表面,利用热喷涂技术制备锌、铝和锌铝合金涂层可以对基体达到长效保护的目的。采用电弧喷涂装制成功制备出了锌铝伪合金镀层,通过中性盐雾试验、扫描电镜(SEM)等手段研究了其结合强度、耐蚀性能并与纯锌、铝涂层进行了比较分析。结果表明,锌铝伪合金涂层的结合强度和耐蚀性能均优于Zn-15%Al合金涂层。
A twin-wire arc-spraying system was performed to prepare pseudo Zn-Al alloy coating so as to improve the corrosion resistance and realize long-term protection of the steel substrate.The adhesion to substrate and corrosion resistance of the pseudo Zn-Al alloy coating were investigated using neutral salt-spraying test and scanning electron microscopy,using Zn and Al coating for a comparison.It was found that the arc sprayed pseudo Zn-Al alloy coating had better corrosion resistance and adhesion to substrate than the Zn-15%A1 alloy coating.
