Titanium has very good corrosion resistance in seawater. At present, there are two methods to make titanium used as anti-corrosion materials for marine structures. One is to make composite clad material with titanium thin plate and organic anti-corrosion material; the second method is to use titanium steel clad plate to clad and weld it to the newly built building. As far as the second method is concerned, there are still two problems, one of which is the joining problem of using titanium as a lining. It is not economically valid to use titanium alone as a structure. It is economical to make the main body of the structure with steel only when the corrosion resistance of titanium is fully utilized. However, brittle intermetallic compounds formed by welding titanium directly with iron are also not practical. Only the "titanium-steel clad plate" which uses the integrated hot-rolling process of titanium and steel, welds the steel part of the clad plate to the main body of the steel structure, and then utilizes the corrosion resistance of the composite material titanium. The second issue is the size of the titanium-steel clad plate. In the past, ultra-thin titanium clad steel plates could not be manufactured. When using this material as a lining material, the size and shape of the plate were too thick. Therefore, the continuous hot rolling mill is used when the thin steel plate manufacturing process is adopted, and the coil-shaped titanium composite thin steel plate with a thickness of only 5mm. The joint strength of the composite steel plate is about 150-200MPa, which is slightly higher than the value specified in the Japanese standard JIS-G3603 and is suitable for use as a corrosion-proof material lining material.
The advantages of ultra-thin titanium clad steel plate are:
(1) Titanium does not corrode basically in seawater, and titanium metal ions will not dissolve out.
(2) Titanium organisms are non-toxic and have no impact on the surrounding ecological environment.
(3) If titanium If corrosion does not occur for a long period of time, it will be an extremely friendly material to the environment.
Titanium-steel clad plate has experienced more than 40 years since its birth, and its main application area has used more than 1,000 condenser tube plates. On the other hand, marine civil engineering has also begun to be used, and there will be more opportunities. Titanium-steel clad plate is the effective use of the excellent corrosion resistance of titanium and the strength of steel, achieving the best combination of cost in terms of cost, and we look forward to further development in this area in the future.
