Cool-drawn 1Cr18Ni9 stainless steel wires of φ 0.1~0.5 mm can be woven and punched to prepare transformable
component which has loose, reticulate structures. When it is uploaded with vibrating force, the displacement will cause
intense frictions between wires' surfaces which will dissipate abundant energy and thus it can serve as dampers like
natural rubbers. Since such new type of material has double characteristics of both rubbers and metals, it is commonly
called "Metal Rubber".
There is certain amount of contact point/surface on wires in the transformable component and the displacements between
wires are at micron levels. Experiments showed that wear course of 'fretting cell' could be plotted as four phases: polish,
adherence, forming of the third bed and stabilization. The stabilization phase, in which the friction coefficients are
comparatively stable, dominates the whole course. Based on data of Metal Rubber vibration fatigue experiment, φ 0.3
mm cool-drawn 1Cr18Ni9 stainless steel wires' dry fretting experiments at 10 N load are made on SRV high temperature
wear tester, friction coefficients are collected and fret traces are studied by laser scanning confocal microscope (LSCM).
Results indicate that wire's stabilization wear phase is the circulation process of grindings' forming, concentrating to
blocks of φ 20 μm, busting and discharging. Deformation induced martensite transit in wire's cool drawing has
significant effects on grinding blocks' bursting performances.
