摘要
本文通过研究喷射沉积6061A1／SiCp复合材料的超声衰减系数分析材料的阻尼性能。实验结果表明:随着超声频率逐渐增大,该材料对超声吸收和散射增强;在一定范围内, SiC体积分数的增大使吸收衰减系数增大,复合材料阻尼性能增强。
The damping properties of the 606lAl/SiCp metal matrix composite, which was fabricated by spray atomization and deposition, were studied by the sting of ultrasonic attenuation coefficients. The experimental results show that,is increasing frequency, the absorbing attenuation and scattering attenuation are both improved. The absorbing attenuation coefficients and damping capacity will also increase with the increase of volume fraction of SiC.
