    摘要:

    利用超声波振动仪研究形状记忆合金Fe-14Mn-6Si-9Cr-5Ni-Nb-Ce在 3.5%NaCl溶液中的空蚀行为,并探讨合金在3.5%NaCl溶液中处于静态和空蚀情形下的自腐蚀电位和极化曲线。结果表明,Fe-14Mn-6Si-9Cr-5Ni-Nb-Ce合金在3.5%NaCl溶液中呈现优异的抗空蚀性能,空蚀率为0.37 mg/h。空化能使Fe-14Mn-6Si-9Cr-5Ni-Nb-Ce合金的自腐蚀电位变负,变化量为–65 mV。在静态和空化两种条件下,Fe-14Mn-6Si-9Cr-5Ni-Nb-C

    Abstract:

    The cavitation erosion of shape memory alloy Fe-14Mn-6Si-9Cr-5Ni-Nb-Ce in 3.5% NaCl solution was investigated by using an ultrasonic vibratory apparatus. Free corrosion potential and polarisation curves of the alloy in 3.5% NaCl solution under quiescent and cavitating condition were studied. The results show that Fe-14Mn-6Si-9Cr-5Ni-Nb-Ce alloy has excellent cavitation erosion resistance in 3.5% NaCl solution, cavitation erosion rate is 0.37 mg/h. Cavitation can shift free corrosion potential of the alloy in the active direction for about –65 mV. Corrosion current of Fe-14Mn-6Si-9Cr-5Ni-Nb-Ce alloy is very low in 3.5% NaCl solution under quiescent and cavitating condition, therefore, Fe-14Mn-6Si-9Cr-5Ni-Nb-Ce alloy shows high corrosion resistance. The relative contribution of electrochemical corrosion rate and pure mechanical erosion-induced corrosion rate to the overall cavitation eroson only amounts to 2.24%
