J. Cent. South Univ. (2021) 28: 648-656 DOI: https://doi.org/10.1007/s11771-021-4634-9 Influence of B4C particle size on microstructure and damping capacities of (B4C+Ti)/Mg composites YAO Yan-tao... GmbH Germany, part of Springer Nature 2021 Abstract: To study the influence of B4C particle size on the microstructure and damping capacities of (B4C+Ti)/Mg composites, in situ reactive infiltration......
was prepared through sol-gel technique. Tetramethoxysilane and 3-glycidoxypropyltrimethoxysilane were used as precursors for the self-assembled sol-gel coatings. The silane colloidal particle size was analyzed by laser particle size measurement. The results indicate that the particle size is in nano-scale and the diameter of particles deceases with increasing dilution times. Gel permeation......
