Iron -based Alloy Plating Remanufacturing Technology is developed from Dong's Iron Plating without Etching Technology, which was invented by the Senior Engineer, Mr. Dong Yuhua of Dalian Maritime University. This technology owned two national patents, and got a lot of awards domestic and overseas. This technology is different than the other iron plating technique. The plated layer shows a kind of micro column crystal construction by microscope, and combines the matrix metal to a whole completely. The plated layer has capability of low residual stress, high hardness, excellent wear prevention and corrosion prevention. By this technology, any thickness could be gain.

At the bonding interface, magnify with scanning electron microscope By 5000 times, it presents a status that the plated layer bonding the metal matrix completely to a whole.
