Abstract

En 中文

• In situ Ti3SiC2 markedly regulated vibration-noise behavior of C/C-SiC. • A favorable Ti3SiC2 content range was identified, with 6.1% most effective. • The 6.1% sample cut mean vibration amplitude from 14.55 to 0.17 m s−2. • Its raw equivalent sound pressure level dropped from 82.66 to 60.05 dB. • A balanced tribofilm state weakened dynamic amplification of periodic shear.
