Study on Dry Tribological Property of Casting Copper Alloy Against Stainless Steel
The dry friction and wearproperties of copperalloy were studied by M-2000-type friction and weartester.The wearaccounts and friction coefficients of friction pairs with different composition of copper alloy against stainless steel under dry friction were measured.The wearing surface was observed using scanning electron microscopy(SEM),and its wear mechanism was analyzed.The results show that the wear mechanism of copper alloy is mainly adhesive wear and abrasive wear.ZQAl 9-4 tin-less bronze in three kinds of copperalloys has a good abrasion resistance and dry friction property.
