| Abstract: |
| The protection technology and protection characteristics of current aircraft landing gear′ s high-strength steel were introduced. Traditional protection technology is mainly chrome and cadmium plating process. There are some new protection technology, such as no-cyanide cadmium-titanium plating, high velocity oxygen flame（HVOF）spraying coatings, and low-hydrogen embrittlement brush cadmium plating. By the contrast of the new protection technology and traditional technology's technological properties and corrosion resistance, it was found that the new protection technology can be used to replace the traditional protection technology. |
