Synthesis and characterization of metal-ceramic composite 316l/sycro

Abstract

The composite formed by 316L steel with 10% of Sr1,8Y0,2CrReO6 (SYCRO) double perovskite was successfully sintered using Top Down nanotechnology associated with powder metallurgy. SEM images showed that the SYCRO nanoparticles were deposited on the steel surface homogeneously. The scattering spectra of the images confirmed the presence of the Sr and Re elements scattered homogeneously on the surface of the composite, which corroborates the images observed by SEM. X-ray microtomography showed a solid build, with few pores and cracks, and a 3D distribution of the main components. X-ray diffraction measurements showed that SYCRO particles were embedded in the 316L steel matrix. Magnetic susceptibility a.c. showed that the composite has ferromagnetism and Tc close to that found in the literature for the ceramic composite Sr1,8Y0,2CrReO6, which certifies that the sintering of the composite was obtained successfully.
