Resumo
Industrial components in gas turbine engines, fluidized bed combustors and catalytic
converters are often subject to the conjoint effect of erosion and high temperature oxidation
processes. Adequate characterization of high temperature erosion-oxidation behavior of
materials involves the reproduction of process conditions such as temperature, impacting
particle parameters such as size, shape, hardness, velocity, impact angle and mechanical as
well as physical properties of the target material. An apparatus to conduct high temperature
erosion-oxidation studies up to 850°C and with particle impact velocities of up to 15 m.s -Iwas
designed and constructed in the Corrosion Laboratories of IPEN. The erosion-oxidation
behavior of high velocity oxy fuel (HVOF) sprayed alloy and cermet coatings of Ni20Cr,
WC-20Cr7Ni and Cr3C2-Ni20Cr on a steel substrate has been studied. Details of this
apparatus and the erosion-oxidation behavior of these coatings are presented and discussed.
