Abstract

Abstract

The wear resistance of TIC-Fe cermet coating prepaid by reactive flame spray of ferrotitanimu, graphic and iron powders was sutdied. It was revealed that the microhardness of TiC-rich and TiC-poor layer within the TiC-Fe composite coatings is 11.9-13.7 GPa and 3.3-6.0 GPa, respectively. A dry wear test showed that their wear resistance is five times higher than WC-Ni45 cermet coatings obtained by traditional process. The major wear mechanisms are surface adhesion and a little stripping of TiC.
