    采用X射線衍射儀、掃描電子顯微鏡等分析手段，對(duì)比研究了四種典型鎳基耐蝕合金在450 ℃/23 MPa下Na3PO4、Na2SO4、NaCl超臨界水溶液中的腐蝕行為。50 h后，合金表層均勻分布著短棒狀、針狀的腐蝕產(chǎn)物，主要組成為NiCr2O4，Cr2O3，NiO，Ni3(PO4)2，CrPO4和Na3PO4等。500 h后，腐蝕層的厚度明顯增大，依據(jù)腐蝕層厚度的增大速度，四種合金的耐蝕性順序?yàn)椋篨-1#>X-2#>625>C-276

    Abstract:

    The corrosion behavior of four typical Ni-based corrosion-resistant alloys in supercritical aqueous solution of Na3PO4, Na2SO4 and NaCl at 450 ℃/23 MPa was studied by using XRD, SEM, etc. After corrosion for 50 h, the surface of the alloys was covered with short rod-shaped and needle-shaped products mainly consisting of NiCr2O4，Cr2O3，NiO，Ni3(PO4)2，CrPO4 and Na3PO4. With the prolong of time, the thickness of the corrosion layers increased and the corrosion resistance was ranked as X-1#>X-2#>625>C-276
