| 摘要 |
The present invention relates to the development of variants of multilayer structural materials with enhanced corrosion resistance, including successively connected outer main layers which directly contact corrosive operating environments on one or both sides of the multilayer material and, disposed there between, alternating internal main and internal sacrificial layers. The main layers are made of metallic materials which are characterized by a state of passivity over a prolonged period with subsequent development therein of pitting-type corrosion, while the internal sacrificial layers, which contact the corrosive operating environment as deep foci of pitting corrosion develop in the preceding outer and internal main layers, arc characterized by the development of general corrosion and have a protective action in relation to the outer and internal main layers. Methods for preparing such materials are proposed. |
