摘要

The tribological behaviors of the high-performance Cu(36)Zr(48)Ag(8)A(18) bulk metallic glass (BMG) under dry-sliding, deionized water and NaOH solution conditions were systematically investigated and the corresponding wear mechanisms were revealed via analyzing the chemical composition and topography of wear track. The results illustrate that the Cu(36)Zr(48)Ag(8)A(18) BMG exhibits tribological properties superior to those of 316 stainless steel under different friction conditions, especially in a NaOH solution. During friction sliding, the formation of uniform and continuous metal-oxide layers on the surface can enhance its wear resistance and protect it from further corrosion by OH-. Furthermore, the NaOH solution and the dissolved products on the frictional surface form fluid-lubricating films, which may also reduce the friction coefficient and wear rate of the material.
