    Abstract:

    Thermal oxidation (TO) process was applied to treat TC4 alloy. Microstructural characteristics of the TO layer were analyzed using scanning electron microscope (SEM), energy dispersive spectrometer (EDS), optical microscope (OM), glow discharge optical emission spectrometer analysis (GDOES) and X-ray diffraction (XRD). Erosive wear behaviors of the TO treated TC4 alloy in CO2-saturated simulated oilfield medium were investigated. The results showed that the obtained TO layer was mainly composed of rutile TiO2 phase. The TO layer presented higher surface hardness and lower mass loss values. TO treatment had significantly improve the resistance to erosive wear of TC4 alloy.
