Abstract:
Solid circular pie-like metal rubbers were made of three stainless steel wires, namely 0Cr18Ni9,10Cr12Mn16Ni and 10Cr21Mn16Ni, and then cycle soak corrosion tests were carried out on these metal rubbers in 3.5wt% NaCl solution for 336 h. The corrosion resistance of the metal rubbers and their static compression and damping characteristics before and after corrosion were studied. The results show that the salt corrosion resistance of the metal rubber made of 10Cr21Mn16Ni stainless steel wire was the strongest, followed by that of 0Cr18Ni9 stainless steel, and that of 10Cr12Mn16Ni stainless steel wire was the worst. Comparing with those before corrosion, the static compression stiffness of three metal rubbers after corrosion all increased while the loss factor kept unchanged or went down. The static compression stiffness of the metal rubber made of 10Cr21Mn16Ni stainless steel wire had the smallest increase range of 4.5% and the loss factor kept unchanged. Meanwhile the stiffness of the metal rubber made of 10Cr12Mn16Ni stainless steel wire had the largest increase range of 150.0% and the loss factor decreased by 31.0%.
