Ti(C,N)基金属陶瓷超微粉在不同液体介质中的分散性研究

Dispersion Behavior of Ti(C,N)-Based Cermet Hard Phase Powders

对Ti(C,N)基金属陶瓷硬质相粉末TiC,TiN和WC的分散行为进行了研究。探讨了不同液体介质和不同表面活性剂对硬质相粉末分散的影响,结果表明:以蒸馏水作液体介质优于以无水乙醇作液体介质;对TiC,TiN粉末,选用聚氧乙烯十二烷基醚作为分散剂具有较好分散效果,而对WC粉末,聚乙二醇是较好的分散剂。

Using two kinds of liquid medium and two dispersants, we investigated the dispersed characteristic of Ti(C,N)-based cermet hard phase powders TiC, TiN and WC. It is concluded that: for TiC. TiN, WC powder, aqua is more suitable than ethanol as a kind of liquid medium. For TiC and TiN, aether is an appropriate dispersant but for WC, polyglycol is considered.
