DEVELOPMENT OF TiB_2-BASED CERMETS WITH Fe-Mo BINDER

摘要

In this study, the wettability and interaction of TiB_2 with melted iron and iron-molybdenum alloys have been investigated. The wetting contact angles were determined, the structure and phase composition of the drops have been investigated by the methods of energy dispersive X-ray microanalysis. The results showed that TiB2-(Fe-13%Mo) system prove to be an optimum one for the new cermets production because of good wetting and minimal interaction between components. The TiB2-(Fe-13wt.%Mo) cermets were produced by sintering in vacuum. The influence of initial TiB_2 particles size on the structure formation of the cermets above has been established.
