Accordingly, the sample treated at 800°C for 40 h demonstrated optimal mechanical performance, achieving a compressive strength of 355 MPa, a Vickers hardness of approximately 8 GPa, and an elastic modulus of 84 GPa.

A nanometer-scale SiO<sub>2</sub> layer was first constructed on the surface of FeSiBC amorphous flakes via an optimized sol-gel route. The effects of reaction temperature and ammonia concentration on coating formation were investigated, and the results revealed that a uniform and dense amorphous SiO<sub>2</sub> layer with a thickness of ∼80 nm was obtained at 30°C and an ammonia concentration of 0.015 mL g<sup>-1</sup>. This coating effectively balanced magnetic dilution and electrical insulation, reducing the core loss from 191.1 to 159.6 mW cm<sup>-3</sup> at 100 kHz/50 mT. On this basis, a phosphate/SiO<sub>2</sub> bilayer coating was developed to further improve interfacial adhesion and magnetic performance. The Fe-O-P bonding enhanced interface stability, while the weak ferromagnetism and flexibility of the phosphate layer mitigated magnetic dilution and promoted particle compaction. The optimized FeSiBC@Phosphate@SiO<sub>2</sub> SMCs exhibited a low power loss of 143.6 mW cm⁻³ (100 kHz, 50 mT), an effective permeability of 74.28, and a DC bias of 57.89% under 100 Oe. Through the synergistic design of a transformational phosphate interface and a ceramic SiO<sub>2</sub> insulating layer, the composite coating strategy achieves reduced loss while simultaneously enhancing permeability.
