Herein, the analytic hierarchy process (AHP) and central composite experimental design in response surface methodology (CCD-RSM) are used to evaluate and optimize the tribological parameters of bionic textured AISI 4140-SnAgCu self-lubricating composite under the conditions of load (L: 20-40 N), velocity (V: 16-32 mm/s), and distance (D: 40-80 m). AISI 4140 biomimetic composites exhibit excellent tribological properties under the conditions of L-27.15/V-16.43/D-40, L-27.05/V-17.08/D-60, and L-27.42/V-17.85/D-80, respectively. The sensitivities of influence factors on the tribological overall score are load, velocity, and distance, in order from high to low. The good antifriction properties of self-lubricating composites under conditions with the optimized tribological parameters benefit from the fact that the solid lubricants are uniformly spread at the contact interface.
