Formula of zinc-aluminum-magnesium alloy coating and application of zinc-aluminum-magnesium alloy coating on highway guardrail
The invention provides a formula of a zinc-aluminum-magnesium alloy coating and application of the zinc-aluminum-magnesium alloy coating on a highway guardrail. The zinc-aluminum-magnesium alloy coating comprises the following components in percentage by mass: 2-3% of Mg, 11.7-15% of Al, rare earth elements and the balance of zinc. According to the formula of the zinc-aluminum-magnesium alloy coating and the application of the zinc-aluminum-magnesium alloy coating on the highway guardrail, the formed coating is good in sealing performance, the finally formed alloy liquid coating is good in salt corrosion resistance and has a self-repairing function, coating components on the periphery of a cutting face are continuously dissolved out after cutting, a compact protective film mainly composed of zinc hydroxide, alkaline zinc chloride, magnesium hydroxide and the like is formed, and the protective film is low in conductivity and has an inhibiting effect on corrosion of the cutting face.
本发明提供一种锌铝镁合金镀层的配方及其在高速护栏上的应用，按质量百分比含量计：由Mg为2%‑3%、Al为11.7%‑15%、稀土元素，余量为锌的成分组成。本发明一种锌铝镁合金镀层的配方及其在高速护栏上的应用中，其中形成的镀层密合性好，最后形成合金液镀层对“盐”耐腐蚀性好，具有自修复功能，切割后切割面周边的镀层成分不断溶出,形成主要由氢氧化锌、碱性氯化锌及氢氧化镁等组成的致密保护膜,这种保护膜导电性较低,对切割面的腐蚀有抑制效果。
