A novel method to fabricate AlN-Al2O3 multiphase ceramic layer on WCu alloy

摘要

A novel approach for the fabrication of α-Al2O3, mullite (Al6Si2O13) and AlN multiphase ceramic layer on WCu via sintering process accompanied with mixing PCS/AlN composite slurry by ball milling was described. The sintering process parameters such as water vapor content and raw material ratio were mainly studied in this paper which greatly affected the formation of ceramic layers. At last, the interfacial reaction was also discussed between ceramic layer and WCu substrate.
