Abstract

In mining industry and metallurgy, several wearing
parts are subjected to the combined effect of abrasive wear and mechanical shocks
that requires materials characterized by high hardness in surface and a better toughness
in volume. In this present study, martensitic steel reinforced Zirconium oxides
as ceramics inserts is manufactured and characterized. Using ASTM G65 abrasive
wear test apparatus, abrasive wear tests of the manufactured steel and of other
materials most currently used in mechanical industry for comparison were
conducted and wear surfaces were also characterized. It was shown that the
manufactured steel allows improving wear resistance by approximately 44 %.
