【摘要】：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336h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%。
[Abstract]:Solid round cake shaped metal rubber was prepared by three kinds of stainless steel silk with 0Cr18Ni9,10Cr12Mn16Ni and 10Cr21Mn16Ni. The corrosion resistance and static compression performance and damping property of 336h in 3.5%NaCl solution were studied. The results showed that the metal rubber of 10Cr21Mn16Ni stainless steel was made of stainless steel. The corrosion resistance of the salt spray is the best, the 0Cr18Ni9 stainless steel wire is the second, and the 10Cr12Mn16Ni stainless steel wire is the worst. Compared with the corrosion, the static compression stiffness of the three kinds of metal rubber increases, and the damping loss factor is basically unchanged or decreased. The static compression stiffness of the 10Cr21Mn16Ni stainless steel wire made of metal rubber increases most. Small, only 4.5%, the loss factor is basically the same, and the static stiffness of the 10Cr12Mn16Ni stainless steel is the largest, up to 150%, and the damping loss factor decreases by 31.0%.
