Surface modification by Friction Stir Processing (FSP) has recently become an increasing research area. Researchers are developing hybrid Surface Composites (SC) with excellent mechanical and tribological properties, using hybrid reinforcement particles. This study investigates the effects of the hybrid mixing ratio of ZrB2 ceramic reinforcement particles added to the material surface to improve the mechanical and tribological properties of Al5083 Base Material (BM). Grooves corresponding to a Theoretical Volume Fraction (TVF) of 15 % were cut on the surface of the material. Particles with a mixture ratio of 1 % ZrB2 - 14 % SiC, 3 % ZrB2 - 12 % SiC, 5 % ZrB2 - 10 % SiC, 7 % ZrB2 - 8 % SiC, and 9 % ZrB2 - 6 % SiC were added to these grooves, and hybrid SCs were produced. The process parameters used in the study were 900 rpm tool rotation speed, 20 mm/min traverse speed, ⁓ 8000 N axial load, 3.5° tilt angle, and single pass. In the test and inspection results, it was determined that the hardness, wear, and tensile test results of the P2 sample with a 3 % ZrB2 - 12 % SiC hybrid mixing ratio exhibited ideal results compared to other hybrid SCs produced. It was determined that the addition of 5 % or more ZrB2 reinforcement particles caused agglomerations in the microstructure and negatively affected the mechanical and tribological properties. The highest hardness value was 112 HV; the lowest volume loss was 2.05 mm3; the highest tensile strength was 279.93 MPa, resulting in 47 % higher hardness, 276 % lower volume loss, and 6 % lower tensile strength compared to the BM.
