This study involved the preparation of TiO2 layers enhanced with Ti3SiC2 phase. was achieved by incorporating particles (2-8 g/L) into an Na2WO4+Na2SiO3+Na3PO4 electrolyte system, utilizing micro-arc oxidation (MAO) technique. The phase composition MAO layer analyzed X-ray diffractometer, surface porosity and elemental distribution were assessed via scanning electron microscopy energy dispersive spectroscopy; cross-sectional thickness measured metallurgical microscope; flatness confocal microscope. friction behavior different contents compared sliding wear tests; anti-oxidation tests used to evaluate resistance layers. results show: 1) addition higher concentrations can increase layer, improve existence numerous “volcanoes” large-sized pores in play a certain “pore sealing” effect. 2) When concentration is greater than 4g/L, enhanced; 3) After at 700℃ for 14 h, (6~8g/L) showed better resistance. would work together atoms Ti block entry external oxygen atoms.
