Abstract: In order to explore the optimal diameter of metal rubber stainless steel microwires, the effect law and
mechanism of the diameter on the friction and wear behavior in small displacement oscillation under different loads and
speeds were studied. And the quantitative relationship between the wear depth and the microwire diameter was
established to evaluate the influence of the microwire diameter on the tribological behavior of the stainless steel
microwire. The results showed that, under the same load and speed conditions, the wear depth of stainless steel wire
decreased with the increase of wire diameter, which was due to the actual contact area of different wire diameters. The
wear depth as a function of wire diameter was polynomial. The friction coefficients of stainless steel micro-wire
increased with the increase of wire diameter, which was related to their actual contact morphology and wear debris
movement state. Meanwhile, the load and speed had no influence of the wire diameter on the friction coefficient and
wear depth of stainless steel wire. However, the stability of the actual contact area between the stainless wires with thick
wire diameter made the impact of the load and speed on their wear depth and friction coefficient significantly smaller
than that on the thin wire test pieces.
Key words: metal rubber; 316L stainless steel wire; wire diameters; frictional wear; wear morphology
