温度的升高, 薄膜的硬度和结合力逐渐增大, 基体温度低于 300℃时, 增大幅度较明显, 基体温度高于 300℃时,
二者增加幅度趋于平缓, 薄膜表现出优异的耐腐蚀性能。
Abstract:TiAlN films were deposited on the surface of Q235 steel by unbalanced magnetron sputtering
technology. The effects of deposition parameters on the morphology, mechanical properties and corrosion
resistance of TiAlN films were studied. The microstructure and mechanical properties of the films were tested by
scanning electron microscope, nanomechanical probe and scratch tester. The corrosion behavior of TiAlN films in
the environment containing Cl- was investigated by salt spray test and electrochemical polarization test. The results
showed that with the increase of N2 flow rate the hardness and bonding force of TiAlN films first increased and
then decreased. When the N2 flow rate was 10 sccm, the film showed the highest hardness and bonding force, 30.7
GPa and 44.2 N, respectively, and exhibited the best corrosion resistance. With the increase of Al target power, the
hardness and bonding force of the film first increased and then decreased. When the Al target power was 90 W, the
hardness and bonding force of the film reached the maximum, that was 28.6 GPa and 38.4 N, respectively, which
exhibited best corrosion resistance. With the increase of the substrate temperature, the hardness and bonding force of the film gradually increased. When the substrate temperature was lower than 300℃ , the increase of the hardness
and bonding force was more obvious. When the substrate temperature was higher than 300℃ , the increase range of the
hardness and bonding force tended to be flat, and the film exhibited excellent corrosion resistance.
