摘　　要：To improve the corrosion resistance of key components and ensure the service safety of marine equipment,here we combined femtosecond(fs)laser fabrication and magnetron sputtering deposition to develop micro/nanostructured amorphous TiNbZr films.Analysis of the compositional,microstructural,corrosion,and mechanical properties was conducted.The results showed that the TiNbZr films were amorphous,and spherical TiNbZr nanoparticles uniformly covered the fs laser-induced periodic fringe structure.A complex hierarchical micro/nanostructure was formed that was hydrophobic and showed enhanced adhesion strength.The TiNbZr films deposited on fs laser-treated substrates provided the best corrosion resistance,showing a self-corrosion current density of 116 nA/cm^(2),excellent passive ability,and pitting resistance.The microscratch test revealed that the micro/nanostructures doubled the binding strength of the TiNbZr/316L interface due to the compositional and structural gradients induced by an approximately 20 nm transition layer formed during fs laser processing.This work provides a new method for obtaining anti-corrosion films with a high adhesion strength for marine applications.
