Abstract

The effect has been investigated of nitrogen ion implantation on the friction and wear behavior of Au26Ag3Ni, Au30Pd29.5Ag1.5Sn, and Au8Ag alloys and electroplated palladium. Rider-on-flat experiments were conducted using nitrogen-implanted (dosage of 2×10¹⁷ ions-cm^-2) and unimplanted specimens in order to make detailed comparison of the characteristics in reciprocating sliding. N ⁺₂ implantation of either the rider (Au8Ag) or the flat (Au26Ag3Ni, Au30Pd29.5Ag1.5Sn) produced a significant reduction in coefficient of friction and in the extent of surface wear sustained during sliding. Layers of electroplated palladium showed only minor change in friction and in sliding damage to the flat following N⁺₂ implantation of both specimen surfaces
