In order to resist the ultrahigh load in the taking-off and landing and turning processes of the airplane, the landing gear device is made of ultrahigh-strength steel commonly, and meanwhile, a combined damping structure of a landing gear piston rod and an outer landing gear barrel is adopted. Ultra-high strength steels tend to be very sensitive to corrosion fatigue and stress corrosion cracking. Therefore, when manufacturing landing gear parts, the surface needs to be protected by certain coating layers, such as a zinc metal coating.
