采用0Cr18Ni9、10Cr12Mn16Ni和10Cr21Mn16Ni三种不锈钢丝制备了实心圆饼形金属橡胶,在质量分数为3.5%NaCl溶液中进行了336 h周浸腐蚀试验,研究了其耐腐蚀性能及腐蚀前后的静态压缩性能和阻尼性能.结果表明:10Cr21Mn16Ni不锈钢丝制金属橡胶的耐盐雾腐蚀性能最好,0Cr18Ni9不锈钢丝的次之,而10Cr12Mn16Ni不锈钢丝的最差;与腐蚀前相比,腐蚀后三种金属橡胶的静态压缩刚度均有所增加,阻尼损耗因子基本不变或下降,其中10Cr21Mn16Ni不锈钢丝制金属橡胶的静态压缩刚度增大幅度最小,仅4.5%,损耗因子基本不变,而10Cr12Mn16Ni不锈钢丝制金属橡胶的静态刚度增大幅度最大,达150.0%,阻尼损耗因子下降31.0%.
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%.
