| description |
High chromium white cast iron alloy used in coal grinding components is amaterial that may present different wear resistance depending on the thermal treatmentused in its manufacturing. In this context, the properties of this alloy, containing 22%chromium and 3% carbon, were investigated after applying different heat treatments andtheir infl uence on the abrasion wear resistance was evaluated. For the characterizationof the alloy, several experimental tests were performed using the following laboratoryequipment: durometer, microdurometer, optical microscope, scanning electron microscope(SEM), X-ray diffraction, emission spectral photometry and equipment for wear testingaccording to the ASTM G65-04 (2010) standard. The results obtained reveal that the wearresistance of the selected alloy increases when a lower amount of austenite is retainedin the matrix and high precipitation of secondary chromium carbides occurs. They alsosuggest that it is not necessary to use long times for the alloy destabilization in orderto obtain higher hardness values and good wear resistance when the alloy is previouslyannealed, in contrast to what is practiced in the industry.
