Heavy-duty anticorrosive coated steel material with excellent resistance against separation and corrosion |
摘要 |
<p>An inexpensive method with good productivity, without coating of titanium metal, is necessary for satisfying the requirement for a long life of a heavy-duty anticorrosive steel material and in order to provide a heavy-duty anticorrosive coated steel material with excellent resistance against separation and corrosion. To respond to this demand, an oxygen-blocking layer is incorporated into the heavy-duty anticorrosive coating, for example, an organic resin sheet (film) capable of blocking the oxygen permeation is stacked or such an organic resin is painted on a conventional heavy-duty anticorrosive coating or a heavy-duty anticorrosive coating subjected to a chemical conversion treatment as the surface treatment. <IMAGE></p> |
