    摘要:

    采用熱氧化技術(shù)對TC4合金進行表面處理,使用掃描電鏡,能譜儀,光學(xué)顯微鏡,輝光光譜分析儀和X射線衍射儀分析熱氧化層的特征,研究了熱氧化TC4合金在模擬油田介質(zhì)中的沖蝕磨損行為。結(jié)果表明:熱氧化層主要由金紅石相組成,熱氧化層具有更高的表面硬度,更低的沖蝕磨損失重。熱氧化處理顯著提高了TC4合金在模擬油田介質(zhì)中的抗沖蝕磨損性能。

    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.
