) Abstract: Self-propagating high-temperature synthesis(SHS) method was used to synthesize ZrB2/Al2O3 composite powders from B2O3-ZrO2-Al system. X-ray diffractometry(XRD) and scanning electron... any interfacial reaction products. It is proposed that the good interfacial bonding of composite powders results from the ZrB2 particles crystallizing and growing on the Al2O3 particles surface......
J. Cent. South Univ. (2019) 26: 88-97 DOI: https://doi.org/10.1007/s11771-019-3984-z Tribological and flame retardant modification of polyamide-6 composite YOU Yi-lan(游一兰)1, 2, LIU Chen-ming(刘晨明)2... retardant mechanism were investigated. The tests show that the formula of the wear resistant PA6 composite (WRPA 6) is PA6/GF/T/PTFE/Gr in the ratio of 100/15/5/10/5 by mass. Because this composite......
