Corrosion Behaviour and Damping Characteristics of a Metal Rubber Material in Simulated Marine Environments

A kind of clamped-edge disk typed metal rubber was designed using 304 stainless steel wires and corrosion experiments for 1 152 h were performed in four kinds of simulated marine environment (full-immersion, cycle-immersion, full-salt-spray and cycle-salt-spray). The marine corrosive resistance and damping characteristics of the metal rubber were studied. The results show that the corrosive rates of the metal rubber in the corrosion environments above-mentioned were 0.033 8, 0.036 0, 0.025 8 and 0.030 8 mm·a-1. After corrosion for 1 152 h, the dynamic average rigidity and dissipated energy of the metal rubber increased and their magnitudes were related to the corrosion rate, and the bigger the corrosion rate, the more obvious the magnitude. The loss factor of the metal rubber was relatively stable and the metal rubber had some ability of marine corrosion resistance.
