Abstract:
The wear
resistance of 28Cr cast iron having different matrices was
studied by pin-disk abrasion test using two kinds of abrasives
(green SiC and garnet). It was shown that 28Cr white cast iron
can be successfully used in the as-cast condition. Furthermore,
the abrasion-corrosion wear resistance of as-cast 28Cr iron and
martensitic 15Cr1MolCu cast iron were compared in media with
different pH values. Results showed that copper alloyed 28Cr
cast iron is more competitive than 15CrMo1Cu cast iron in
certain environments. In addition, the mechanical properties of
28Cr cast iron with different pH matrices and different carbon
contents were measured in order to provide a basis for
engineering applications.
