Abstract: TiN/TiCN film was prepared on AZ31 alloy by reactive magnetron sputtering and the deposited film was subjected to vacuum stress relief annealing. X-ray fluorescence spectrometer (XRF), scanning electron microscope (SEM), grazing incidence X-ray diffraction(GIXRD) and electrochemical workstation were used to analyze the surface chemical composition, surface morphology, residual stress and corrosion resistance of all the films before and after annealing. The results show that the films are composed of TiCN and TiN with FCC structure. After annealing, the grain size and crystallinity of the films increase, the residual stress decreases significantly, the content of Ti, C and N elements in the electrochemical corrosion area decreases, the corrosion resistance of the film annealed at 250 ℃ is equivalent to that of the deposited film, and the corrosion resistance of the film annealed at 300 ℃ decreases.

Key words: annealing temperature, TiN/TiCN films, magnetron sputtering, residual stress, structure, corrosion resistance
