Abstract：

In　this　study,　the　tribological　behavior　of　a　Ni-free　Zr53Al16Co23·25Ag7.75　bulk　metallic　glass　(BMG)　was　investigated　in　dry-sliding　and　simulated　physiological　media　using　ball-on-disk　reciprocating　friction.　The　effects　of　sliding　load,　speed,　media　and　counterpart　materials　on　the　wear　resistance　of　the　Zr-Al-Co-Ag　BMG　were　illustrated.　Under　dry-sliding　in　air,　wear　resistance　of　the　Zr-based　BMG　decreases　with　increasing　sliding　load,　and　wear　deterioration　is　controlled　by　oxidation　and　abrasive　wear.　With　increasing　sliding　velocity,　larger　plastic　deformation　occurs　on　the　surface　of　BMG　due　to　the　frictional　heat.　The　BMG　exhibits　decreased　wear　resistance　in　0.9%　NaCl　and　phosphate　buffer　saline　(PBS)　solutions　in　comparison　with　that　in　air　and　deionized　water,　which　is　probably　associated　with　tribocorrosion　controlled　by　synergistic　effects　of　abrasive　and　corrosive　wear.　The　wear　resistance　of　the　Zr-based　BMG　against　Si3N4　counterpart　material　is　inferior　to　that　against　ZrO2,　whereas　the　case　is　contrary　to　that　against　Al2O3.　The　effect　of　ceramic　counterpart　materials　on　the　wear　resistance　of　BMG　is　discussed　based　on　their　Young＇s　modulus　and　fracture　toughness.　©　2016　Elsevier　B.V.　All　rights　reserved.
