Abstract
In this study, a wear test was carried out to clarify the effects of the experimental potentials on tribocharacteristics of metals against alumina(Al2O3) in 3% NaCl solution and under different potentials. We used an oscillatory type, and a cylinder-on-disk type test apparatus. As the results show [phosphor bronze(PBB2)] a generally higher wear resistance and lower coefficient of friction than with either carbon steel(S45C) or stainless steel(SUS304). But it does show a lower wear resistance under corrosion potential (COP(+250mV)) than with them. SUS304 shows a generally lower wear resistance and a higher coefficient of friction than with either S45C or PBB2, though it shows a higher wear resistance under corrosion potential (COP(+250mV)). The wear resistance of S45C is easier to receive the effect of the experimental potentials in PBB2 and over SUS304.
