In this paper, the effect of heat treatment (760–1060 °C) on tribological behavior of selective laser melted Ti6Al4V alloy against Si 3 N 4 counter-ball under different applied loads was investigated. Results show the wear rate of as-built Ti6Al4V alloy increased firstly and then gradually decreased with increasing the heat-treatment temperature, which obtained the lowest value when the heat treatment temperature was 1060 °C, exhibiting the best wear resistance. The higher applied load led to larger wear rate and lower coefficient of friction. The wear mechanism was strongly dependent on the microstructure transformation, micro-hardness and applied load, which was discussed in detail. • Ti–6Al–4V alloys were fabricated by selective laser melting. • Friction coefficient and wear resistance were optimized by heat treatment. • Higher applied load led to larger wear rate and lower friction coefficient. • Wear mechanism was strongly dependent on the microstructure transformation, micro-hardness and applied load.
