Abstract
This paper is a study of the influence of fluidized bed carburizing of sintered steels on the mechanical properties and the abrasive wear behavior for two different types of powder. Carburizing was carried out at a temperature of 900 °C and maintained for 20 minutes and 40 minutes, respectively. It was found that the best values for Vickers microhardness and abrasive wear were recorded when the carburizing time is 40 minutes for powder P2.
