In this study, two high chromium cast irons
(HCCI) with different chromium content (15%Cr and
25%Cr), in as-cast and annealed conditions (heat-treated,
HT), were tested to determine the erosion wear behavior of
these alloys. Erosion tests were done using a gas blast sand
facility with high erodent particle velocity (90 m/s) and high
erodent feed rate, at an impact angle of 45°, which represents
conditions similar to service conditions of some components
of thermal power plants using pulverized high mineral content
coals. To identify erosion mechanisms, microstructural
characterization was done by a scanning electron microscope
on samples before and after erosion tests. Identification of
microstructural phases was done by X-ray diffraction analysis.
The main results of the tests shown in this paper indicate
that matrix plastic deformation and distribution of carbide
phase have a significant contribution to erosion resistance of
HCCI alloys in severe erosion service condi...tions.
