The invention discloses a method of improving moving iron receiver coil corrosion resistance performance in the technical field of moving iron receivers. The method particularly comprises steps: a vacuum evaporation method is adopted to deposit a protection material on the surface of the moving iron receiver coil, and a protection layer is formed, wherein the deposition temperature of the protection material on the surface of the moving iron receiver coil is firstly increased and then decreased. Compared with the prior art, the method of the invention has the beneficial effects that the density distribution of the protection material on the surface of the moving iron receiver coil is adjusted, layered distribution of density to looseness to density of the protection layer is finally realized, and the distribution structure can achieve excellent corrosion resistance effects; due to the density-looseness-density protection layer structure, the damage caused by the internal stress of the moving iron receiver coil can be reduced, an external force can be well buffered, and the scratch resistance effects are good; and falling of the protection layer is prevented, enough aesthetic feeling is particularly realized, and the method is more applicable to an automatic process.
