Study on the Thermal Oxidation Surface Modification and Deformation Behavior of NiTi Alloys
Published 2025-07-01“…In order to investigate the effects of thermal oxidation surface modification on the properties of NiTi alloys,the effect of preparing oxide films on NiTi alloys by thermal oxidation technique at different temperatures (300~700 ℃) in atmospheric environment was investigated.The research primarily focused on analyzing the morphology,composition,phase structure,phase transformation temperatures and mechanical properties of the Ti-O films formed at different thermal oxidation temperatures.The influence of thermal oxidation on the superelasticity and shape memory effect of NiTi alloys was investigated through tensile tests and water bath heating method.The surface morphology,phase structure,phase transformation temperatures and hardness of the thermally oxidized samples after plane stretching and water bath heating were characterized using scanning electron microscopy (SEM),X-ray diffractometer (XRD),differential scanning calorimetry (DSC) and hardness testing.Results showed that at lower thermal oxidation temperatures (300~400 ℃),the oxide layer formed on the NiTi alloy surface was very thin,and no titanium oxide coating was detected.When the thermal oxidation temperature reached 600 ℃,a dense rutile-TiO2 film formed on the surface,but it was prone to cracking and peeling after tensile deformation,exhibiting poor film-substrate adhesion,which was insufficient to meet practical application requirements.Tensile and water bath heating tests showed that when the thermal oxidation temperature exceeded 400 ℃,the reverse phase transformation of the NiTi alloy during unloading could not be completed,leading to a degradation of its superelastic properties.However,after water bath heating,the B19’→B2 martensitic reverse phase transformation was completed,indicating that high-temperature oxidation did not affect the shape memory effect of the NiTi substrate.These results provided important theoretical and experimental references for studying the film-substrate adhesion and coordination properties of thermally oxidized NiTi alloys.…”
