Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the drawings in the present invention, and the forms of the structures described in the following embodiments are merely examples, and the corrosion-resistant flat steel according to the present invention is not limited to the structures described in the following embodiments, and all other embodiments obtained by a person skilled in the art without creative work belong to the scope of the present invention.
The first embodiment is as follows:
referring to fig. 1 and 2, the present invention provides a corrosion-resistant flat steel, including: the flat steel body 100, the fixed welding in top of flat steel body 100 has magnesium alloy protective layer 110, and the fixed welding in bottom of flat steel body 100 has bottom aluminum alloy protective layer 113, and the both sides of flat steel body 100 all fixed welding have side aluminum alloy protective layer 112, and magnesium alloy protective layer 110, side aluminum alloy protective layer 112, bottom aluminum alloy protective layer 113 all fixed welding each other.
The working principle is as follows: it is to be noted that the flat steel body 100, the magnesium alloy protection layer 110, the side aluminum alloy protection layer 112, and the bottom aluminum alloy protection layer 113 are all fixedly welded, so that the flat steel body 100, the magnesium alloy protection layer 110, the side aluminum alloy protection layer 112, and the bottom aluminum alloy protection layer 113 are all in contact with each other, when electrochemical corrosion occurs, such as rain wash, an electrolyte solution in rainwater first contacts the flat steel body 100 and the magnesium alloy protection layer 110, and forms a primary battery, since the magnesium alloy protection layer 110 is mainly made of magnesium metal, the flat steel body 100 is mainly made of iron metal, and the metal activity of magnesium metal in a metal activity sequence table is higher than that of iron, so that magnesium metal in the primary battery is an anode, undergoes an oxidation-reduction reaction and is gradually consumed, and iron metal is a cathode, and is well protected, and similarly, when rainwater contacts the side aluminum alloy protection layer 112 and the bottom aluminum alloy protection layer 113, both of magnesium metal and aluminum alloy are also in contact with the flat steel body 100 to form a primary battery, the main component of the side aluminum alloy protection layer 112 and the bottom aluminum alloy protection layer 113 are aluminum alloy protection layer 113, and the metal activity of iron in a sequence table is greater than that of iron, and are consumed in the flat steel body 100, thereby protecting the primary battery, and are used as an anode.
Example two:
referring to fig. 3, the difference between the second embodiment and the first embodiment is: the combination block 117 is arranged on the flat steel body 100, the two flat steel bodies 100 can be connected through the combination block 117, and the connecting part of the two flat steel bodies 100 is connected with the limiting bolt 118 in a penetrating manner.
