Effect of Fluidized-Bed Carburizing on Mechanical Properties and Abrasive Wear Behavior of Sintered Steels
Keywords:
powder metallurgy, fluidized bed carburizing, abrasive wear
Abstract
In this paper is studied the influence of fluidized bed carburizing of sintered steels, for three different types of powder. Carburization is one of the most popular variety of temochemical treatment. Usually, carburization occurs in the temperature range of 850-950 ºC. In powder metallurgy, the carburization had a great importance to establish the dependencies between porosity and their ability to take carbon.
